Belva Subwoofer Boxes with Polyfill and 3/4-inch MDF

Built for Bass

You've got an awesome subwoofer there, pal. But where's it gonna go? You can't just throw that thing in the trunk and call it a day. Don't worry, Belva's got your back. With superior construction, great features and everything you need for bass, you'll be ready to pass up that entry-level box you've been eyeballing.

Belva Subwoofer Boxes are CARB Phase 2 Compliant

You get quality boxes with solid 3/4" MDF because nothing else will do the job right. You want to flex your windshield, not your box's innards. You get polyfill built into the box, making sure your subs perform perfectly. On top of that, you get a box that's CARB Phase 2 Compliant, meaning your box won't emit as much nasty formaldehyde as the competition. Better for your bass and better for you.

Belva MDF 3/4-inch Thickness

Look, nobody buys a subwoofer and says, 'Aw man, I just want a teeny bit of thump.' Naw man, you want something that kicks you in the chest, but you need a box that's gonna put up with it. That's where Belva comes in. While other brands use less-than-optimal 1/2-inch MDF, we've got 3/4-inch MDF to make sure you get all the bass you can handle. Why risk a busted box? Belva's the obvious choice when it comes to giving your sub a good home and giving you the low end you're looking for.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Brutus (Hifonics)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
900 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
450 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
2.5"
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
84 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
11 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Polypropylene
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Butyl Rubber
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Single Stacked
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.25 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.5 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.5 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
5-9/16"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
10-15/16"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
30.91 Hz
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
45.59 liters
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
0.65
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.
0.76
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
7.704 ohms
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 – 10.

I would recommend this product for the guy's out there that are serious about their music. If you got good, high quality subs, then this box will make them perform to your sub's max output with out worry of blowing up your box.

I am on a budget, like most of us. I needed a nice looking box for a reasonable price. For $52.00 you can't beat it.
I loaded my 2 12" Alpine TypeS subwoofers in it. Mounted my amp to the back and they are still going strong.

I got my complete set up: 12" kicker subs box 1000watt Mbquart amp and amp kit. I have always installed my own equipment, I found it helpful that they have videos that covered some of the product they carry. There are a few shop's in Texas like Best buy and Custom Sounds that offer equipment. But the professionalism of the knowledgeable staff the price and the reliability made it clear that I wanted to do business with them.

The following review is for MDFD12, which is a part of the bundle you are viewing.

Appears to be fairly well built. Arrived with a little dent and a tear but its too little to bother with. Sounds nice but doesn't hit as deep as I would have liked. Small size however, leaves me some room for a couple of bags of groceries. Three stars for durability since I've only owned this for about a month.

October 4, 2013

The following review is for MDFD12, which is a part of the bundle you are viewing.

Solid sealed enclosure. Two of them barely fit in the back of my 02 Focus SVT 3 door. The binding posts are cheap, I tightened them as I would other posts but one out of eight wouldn't tighten because the thread tolerance is poor and it acts like its stripped, I can get some pressure on the wire but I worry it will come loose. Probably worth spending a little more money on a better enclosure but it works fine if you're on a budget.

This enclosure is a well built enclosure for sq applications. I purchaced to house 2 CV vmax 122 drivers and the sound quality was almost rubbery? not tinny, never a crackle....fluid almost..... call it a well dampened sound with minimal distortion. just clean bass all the way into the 20s. made sounds i diddnt know existed. if you dont care how your music sounds and just looking for loud, look elsewhere. my only complaint, 11" cutout is too small for the vmax and the black carpet is difficult to follow a line with the router.

The box is very good at 1.25 cubic feet. I'm running 2 12's with 800 watts rms and it hasn't shattered. Wish it was 1.35 cubic to accommodate for subwoofer basket displacement but it still makes makes subs hit ridiculously hard. Polyfill helps make the box seem bigger due to mechanics and the "Q" point. I really couldn't be happier!

Ok so I bought this box because I wanted a quick sealed enclosure for my 2 JL W3's. The box is made pretty solid, true 3/4 MDF but the caulk job on the inside was kind of off but that's nitpicking. Haha after 3 weeks though of pushing my W3s the top of the box is leaking air. So not the best made but definitely a good pre fab and pretty cheap. Can't really complain. It is nailed together tho so yea..

The following review is for MDFD12, which is a part of the bundle you are viewing.

i bought this box about a year ago for 2 of my infinity reference 1260w subwoofers. I have two more in a ported box. im pushing 350w to all 4 and I have to say I like this box more than the ported. you feel it more in the sealed box but lose a little on the db's but its worth it. the box is sturdy and hasn't showed wear a bit. its tuned in the lower 40's so you wont get stupid low with it but can get loud. I would recommend it to anyone on a budget or to lazy to build their own box. it comes with polyfill which is a bonus, the terminals on the back need calked but that's with about any box you buy. overall I like it and would buy again if I had to.

The following review is for MDFD12, which is a part of the bundle you are viewing.

This is a great box. I prefer ported but my trunk is too small for it so I had to go with sealed. I'm still happy though. This had the perfect size for my 12s. Also the measurements are a little off. The box is a little bigger that the description said.

February 20, 2012

The following review is for MDFD12, which is a part of the bundle you are viewing.

Installed this weekend, I did add a couple pounds of "pillow stuffing" since the box was a tad smaller then what I needed. I have noticed some flex already but im not suprised with the subs that are in it. I will add triangle shaped gussets and some "trim screw" to try and hold things together.

A sheet of real MDF (not the cheap underlayment) is $32, carpet and glue around $15 so for what they want for this its a good deal that just needs some minor tweaks.

Perfect size to fit my Infinity subs. Wish it came with mounting feet but can't ask for everything. Quality is legit for the price. Just your average rectangular box. Fit in the trunk of my 240sx which is pretty small.

The following review is for MDFD12, which is a part of the bundle you are viewing.

This box looked great and felt very durable. My subwoofers wouldnt fit at first so I had to do some shaving, NO PROB. It sounded good for awhile and I loved it. After about two weeks, it lost its sound, went to check out the problem the whole front of the box had almost came off, Box was sealed very well, too bad they used nails instead of screws, would have been a very good box.

I did have to spray a little adhesive inside for 1 part of the foam & terminals were screwed in & not exactly straight & I also had to poke holes in the foam for wires but these things are no problem. The box is awesome & I will by more in the future

Extremely well built

June 22, 2006

The following review is for MDFD12, which is a part of the bundle you are viewing.

Insanely well built box.

Carpet job is top notch, Good quality carpet stretched perfectly over the box. All joints are glued and caulked well. theres no need for extra bracing here but you may add some 2x4's to reduce the airspace if needed. The gold push terminals are well sealed in place.

Hits low and hard with all sub's I've thrown at it (JL Audio 12W04's, Rockford Fosgate P312D4's, Kicker CVX12's and finally Alpine SWX-1242D's)

Don't be afraid of the price. It's a perfect price for a box of this caliber. Would recommend it to anyone.

best box 4 the buck

April 24, 2006

The following review is for MDFD12, which is a part of the bundle you are viewing.

Don't let the skimpy price fool you. This box is made very well and it's ready to go. The joints are already caulked and glued - so there is nothing more to do than mount you speaker.

It's not MDF(medium density fiberboard) like all the others, it is made from HDF; high density fiberboard. HDF boxes are typically stronger, stiffer, and lighter than MDF enclosures. The box does not require any additional bracing because of its density. It has a high an undetectable high frequency resonance and doesn't color the sound of your bass with unwanted buzzing or flexing. The HDF box is lighter than MDF because it has smaller fibers that when pressed and heated require less glue and resin to bind the fibers together.

The speaker terminals are screw type gold plated binding posts that will hold 12 g speaker wire easily. They screw into the enclosure for added strength and a tighter seal.

Just make sure that you do your math and pick the right sub for the cubic feet and stuff with poly fiber fill.

Great box. Quality carpet job, all seams sealed correctly and well, and the terminals are strong and functional. Perfect basic box to make two twelve's hit perfectly. Just remember this is a sealed box, so it will have a differnet sound than that of a ported or bandpass box, but if u want a tighter hitting bass, this box if perfect.

Nice heavy, good sounding box. I would reccomend putting some polyfil to "cushion" the backfire of the subwoofer, really helps w/any sealed box and totally makes a valuable difference considering it only costs about 5-10$ more. The box itself is well sealed and well made, the connectors on the inside and out are really easy to use and once connected your wires will stay put.

Chose these for the rubber surrounds, non paper cones, and DVC power rating to match my Kenwood 2 channel 900 watt amp. Put them in a Ground shacker bandpass box and they sound pretty good. After break in the output is definately enough to keep me happy :) They are made in China unfortunately and I have not hooked up the led lights nor do I intend to at the moment. This is the first Hifonics products I have owned and must say am impressed by the performance. The trim ring is plastic so be careful when installing as I could see that getting cracked easily by torqueing down the screws to much all at once.

The following review is for MDFD12, which is a part of the bundle you are viewing.

Ordered my box and had it at my front door in 2 days! Great box. Its very well built and pure mdf and thick mdf wood. Nice carpeting. Only down fall i see is there was no poly fill and terminals are on sides instead of rear. I thought it was suppose to be this one pictured and both are the same numbers but different box but i am still very very pleased!

The following review is for MDFD12, which is a part of the bundle you are viewing.

This is a very well constructed box, well sealed and solid. However, mine arrived new in the box and every corner had the carpet worn off and bare wood showing. Also, mine was not lined with poly-fil and the terminal cups were on the sides rather than in the back as it appears in photos- no biggy but that did influence my decision as my install would have been a little "cleaner". All in all it sounds great and seems extremely durable.

I always try new subs in a sealed and then ported box. This Belva is a great value and a solid , sharp looking sub box.

I have to LMFAO at all those bad reviews bet they never realized 3 weeks. At lest before you go n turn up amp. Today is Aug 19. 3 weeks ago I bought n installed (DIY). My amp n remote were both turned to 2 gain will EVERYTHING ELSE was set 0. Yes at first could not hear it. But in long run worth it. By 5th day at 2 gain was raddling my mirrors. I only got one these bad boys. Due to out stock. I can't even fathom 2 these. Guys going.BTW I still haven't messed with amp or any settings. Pounder on that for awhile.....

I ordered this box for a pair of AudioFrog gb12d4-12, the box came with a couple of nicks from shipping. And didn't have the poly fill. Customer service was on point.

Best Value!

March 10, 2017

The following review is for MDFD12, which is a part of the bundle you are viewing.

This was already the best deal for a 3/4" MDF dual enclosure I could find, everything else in this range is 5/8".

For the price I wasn't expecting much.
However When it arrived found it is of good build quality, with decent carpet.

They already lined the inside with polyfil, more added value.

Then to top it off, found it has really nice gold plated screw type wire terminals. Better connection and added peace of mind that connections will not come undone.

This is probably the best deal/value on the internet for a dual 12 enclosure. Probably why it's backordered at time of this review.

Very Happy!

Killer Bass

January 29, 2017

The following review is for BRX12D4, which is a part of the bundle you are viewing.

Pushing these with an old school Rockford 500 watt RMS amplifier and the bass is deep and loud. The LED is just plain cool looks killer at night. Well made no short-cuts in manufacturing. Seriously Hifonics is making a great comeback.

The following review is for BRX12D4, which is a part of the bundle you are viewing.

purchased this sub to replace a former one. Has a rich solid sounding bass that is more than enough for my compact car. The blue LED lights were easily connected to the remote turn on and negative terminals on my amp for added appeal.

Awesome with my dual JL 12w6v2's

March 8, 2016

The following review is for MDFD12, which is a part of the bundle you are viewing.

Purchased because I needed a new box for my JL Audio W6v2's. Sounds great! Great solid construction, nice that it's already lined with polyfill, no air leaks and the black carpet looks great. Can't beat it for the price and sound quality with my subs in it is excellent. Guess it would be nice if the terminals were pre-wired but I soldered my own wires in. Love it, would buy again Box fits perfect in my '13 Accord trunk

Fantastic Sub Box

February 26, 2016

The following review is for MDFD12, which is a part of the bundle you are viewing.

A very well-built and nicely carpeted sub box, that looks great, and should prove to be very durable, as it is constructed with 3/4" MDF instead of thinner material of many other boxes costing more than this.

The black carpet makes more of an impact than the typical gray carpet, and the 5-way binding posts are much higher quality than the typical plastic spring connections normally found on sub boxes.

Very happy with this purchase, and would absolutely consider another should it fit my needs of enclosure volume. (It's not worth the extra time/effort to make a custom box, when this does the job just as well, and comes pre-lined with poly-filled and pre-carpeted)

Comes with literally everything you'd need, fits perfectly in my 2014 dodge charger rt. Only think I had to buy in addition was a gauge to be able to lower the volume on the bass. Other then that I love it!
