September 17, 2013

The following review is for MDFS12, which is a part of the bundle you are viewing.

After receiving the Box, I promptly installed it and began tuning my subwoofer and amp. Wow. Not only did the bass sound punchier, which was expected, it sounded much clearer and did not overlap my OEM speaker in my 02 Jetta.
The box is definitely a key component in my audio setup and I would recommend this product to any of my friends looking for this type of product.

Well Constructed, Nice Box

September 14, 2013

The following review is for MDFS12, which is a part of the bundle you are viewing.

I only give it 4 Stars because I purchased this originally because the specs listed this box as having a 1.25 cu. ft. internal volume. I ideally need 1.25 cu. ft. for my Kicker Comp12. However, this box is 1.0 cu. ft.. The webpage was updated after I received mine. Still I kept the box, put a little more stuffing in it than required to make the sub think the box is even larger.

Other than that the box is very well constructed. I you were using it for a high powered 600W RMS or greater sub I would reinforce of the corner joints with wedges or corner braces for added stability (remembering to subtract the volume of the wedge braces, especially, from the internal volume). Meaning This box would be good for high powered shallow mount subs with a Vas slightly under 1.0 cu. ft..

Great Enclosure For The Price!

August 21, 2014

The following review is for MDFS12, which is a part of the bundle you are viewing.

I received this enclosure via a package deal from Sonic Electronix with the Infinity Kappa 120.9w. They are a great match! The enclosure matches the subwoofer manufacturer's recommended sealed enclosure size.

This enclosure arrived in perfect condition, with no air leaks. I have tested out the Infinity 120.9w woofer with 600 wrms pounding to bass heavy music, and the enclosure held strong.

The terminals provide the option for banana plugs or direct wire from the amp using the screw down option (which I chose because I have no banana plugs on hand). I may be getting some banana plugs just for easier connect/disconnect.

The fact that the enclosure carpet (black) matches my Lexus trunk carpet perfectly is a nice bonus.

I did add some extra poly-fil - the amount that came with the enclosure was one thin layer around the interior of the box - not enough for my liking. I bought some poly-fill and packed the box half full.

This enclosure should last a long time - it is very solid and well made. I also like that the sides are inset about 1/4", allowing for easy grip when lifting the enclosure.

Pretty good for money but...

March 27, 2014

The following review is for MDFS12, which is a part of the bundle you are viewing.

Overall, this enclosure is fantastic and it is a great value if you didn't want to build a custom enclosure like myself, but there is one thing that is wrong in the description... on both sides of the box, the left and right when looking from the front, are recessed 3/4 of an inch, leaving a lip on both sides that is 3/4 of an inch tall, so it changes the internal volume of the box by a small amount, around 0.14 cubic feet. Not a big difference but for some that is a deal breaker. it does come with a small amount of polyfil, enough to cover all 4 solid sides. Otherwise, great buy! Still worth 5 stars in my opinion i just think they need to be more specific with the outside dimensions.

Side note: the lip on each side is a nice addition and it adds to the visual aesthetics of the box and also serves as a nice place to mount your amp so it sits a little recessed on the box like I did with my Alpine MRV-500 monoblock amp!

Belva 1CF 3/4" Sub Box

April 25, 2014

The following review is for MDFS12, which is a part of the bundle you are viewing.

I didn't expect much for the Price. I was Pleasantly Surprised. This Box is Well Made. Extremely Well Made for the Price. The Binding Posts are Gold with Decent Quality. The Box has some Batting inside, though I added about twice as much more to it. You could use Slip On Connectors on the Inside of the Binding Posts, but I chose to Solder. This Box is subjected to Lots of Vibration and I didn't want anything working Loose. The Speaker Opening is a Perfect fit for my Sub. I tried to add Sealing Tape to make it Tighter, but it was already so tight that the Sealing Tape wouldn't fit, so I left it Off. I've been driving around for several weeks now and not a rattle. I'm extremely Surprised and Satisfied with this Sub Box.

January 13, 2013

The following review is for MDFS12, which is a part of the bundle you are viewing.

I love the quality of the box itself. It has held up very well pushing my 12" VVME. I purchased this enclosure because it was the cheapest I could get at the time. However, I am upgrading now that I can afford a ported box. The carpet is a very deep black and the box itself is rather small, granted it is a sealed enclosure with only 1.2 ft of volume. Ultimately, I would recommend this subwoofer to anyone looking for an affordable sealed box that fits in their trunk and sounds great!

Switched to a sealed box for my Alpine Type-X. Much better SQ! Now I can push more power, and have more accurate bass. Box was well built, as described, but contained a minuscule amount of fiber. Not sure how well this affects the box, but I'm happy overall... so it's fairly a minute thing to worry about anyways.

July 13, 2007

The following review is for MDFS12, which is a part of the bundle you are viewing.

I use this sub for Alpine Type-X that has a huge magnet and runs at 1000W. I realized that this enclosure is not big enough for big-magnet subwoofer since the remaining space is less than 1 cubic ft. If you're gonna use it for Type-R, W6 and smaller sub, this enclosure is the one you're looking for.

overall box is build solid and has now sealing issues like some slighter cheaper ones found on amazon.com. I was a little disappointed in the foam packing, the picture on the ad looks like it has a decent amount in the box, in real life is was very thin just enough to line the inside walls. Overall sound out of it is very good, deep, clear bass.

The following review is for MDFS12, which is a part of the bundle you are viewing.

I recently upgraded my entire subwoofer system and this was the box I chose, for the price it is unbeatable. I have a Pioneer 12 inch champion series dual voice coil subwoofer in the box being powered by an Alpine MRP-M500 class d amp running at 500 watts at 2 ohms this combination sounds perfect. I have had many other setups before this. And I bought my current set up the be the end of my car audio line. I could not be happier with everything that I chose. The subwoofer sounds so good in this box being powered by the amp I have the lows are like butter and the highs are not unbearable. I highly recommend this box.

I recommend this box for anyone who wants a simple, clean, quality built box. It works well and has clean bass in my trunk. It has the bare minumum of poly fil for this box, it wouldn't hurt to add a little bit more since this is a smaller squared box for a 12' sub. Need something to mount it with also.

This box is awesome. I have a short extended cab truck, and it really produces some tight crisp bass for the amount of room that I have.

Even though this is only a 250 watt sub. If you hook up two of these, then you'll have a pretty good amount of bass. I defiantly wouldn't run these over 300 watts of constant power. Very good sound quality excellent. And my favorite part is that this sub isn't to particular with the size of the enclosure. As long as it's pretty close to what it's supposed to be. Unlike Alpine type r's where the box has to be perfect for the sub otherwise you wont get the best performance you can.

These things pound in a sealed enclosure with a little amp, with a big amp they pound with a ported enclosure. I used to own 2 p1s4-10. But then i decidedi needed to upgrade my system. i would highly recomend these if your looking for some hard hittin bass in the trunk.
(P.S.my friends are jealous of these)

not up 2 par

April 22, 2012

The following review is for P1S4-12, which is a part of the bundle you are viewing.

I have one of these in a ported box running off a p300-1, i have the 4ohm woofer. To start off with do not, i repeat do not over power this woofer it will fry it instantly. Hooked a t1000-1bd and it lasted 15 min. The woofer would get extremely hot just on the p300, and would distort after a good hard 20 min of playing, the woofer has great mid and low bass but the deep stuff is just out of its league. I know what your thinking well ya its going to fry on a t1000 but i put a sundown sa10 on it and it played for months.

Great Sub

December 11, 2011

The following review is for P1S4-12, which is a part of the bundle you are viewing.

This was my first sub woofer I have ever got for my truck and I was very pleased with its performance. I paired it with a kenwood 350watt amp. The sub was way underpowered. It was only getting 150rms. The sub woofer had a fairly good sized magnet considering its only a P1. However it is time to upgrade so i just ordered a Rockford Fosgate T0 2 Ohm 12" sub for Christmas. This product is recommended for beginner system.

The following review is for MDFS12, which is a part of the bundle you are viewing.

With my brother's help trimming the existing 12” hole (for the passive radiator), and cutting a new 10” hole (for the subwoofer)on the opposing side, I have one kick-butt sub-woofer in the back of my black 1999 Mazda Protégé ! There's plenty of clean, tight, low bass. It even blows-away my Infinity bass-link that I had for about 5 years.

What I have:
amplifier for sub-woofer (Precision Power i650.1)
subwoofer (Earthquake Sound DB10)
passive radiator (Earthquake Sound SLAPS-M12)
sealed sub-woofer enclosure (Belva MDFS12)
receiver (Kenwood KDC-X898)

P1's Bang!

May 16, 2013

The following review is for P1S4-12, which is a part of the bundle you are viewing.

I had a rockford 550 amp going to these and they were amazing. Given that I would blow them every year. I wanted to go P2's but skipped it and went to L7's. Great sub as long as you got the right power to it. I had too much, so that was my mistake. But compared to any other brands low wattage subs, these are by far the best. I could be wrong because I had to much watts rms going to them but still liked them. Remember when you purchase something and especially beat, you get what you pay for.

"Free Special" 12" box

December 28, 2015

The following review is for MDFS12, which is a part of the bundle you are viewing.

You will have to modify the box before use. It may have 1/2 lb of synthetic fiber. The caulking along the seams was poorly done and as a cost savings initiative it may have 6 finishing nails holding it together. I had to reinforce it, seal it, and add over a pound of fiber to quiet the gorilla inside the box. It sounded like he was going to bust out of the cage. But now the box sounds of good quality as it is 3/4" MDF and the cutout was perfect.

Box is good, terminals are garbage.

January 30, 2018

The following review is for MDFS12, which is a part of the bundle you are viewing.

I have a 4 ohm dual voice coil dc that I wanted to hook up in parallel to itself for a 2 ohm load(both positives and negatives hooked up on each coil) the inside connections being like a speaker plug does not allow for a dual voice coil connection and seems to thin for higher power. Trying to rig it I broke one and saw the center of the metal....it’s a sad sight, like breaking a cheap Walmart knife. Air pockets and not even brass or copper, clearly a cheap coated composite. I went and bought two solid brass machine screws with brass nuts and copper washers using rings on the ends on my wire to tighten everything down for a good solid connection inside and outside the sub box, then sealed with roof tar(don’t use roof tar, it’s nasty stuff) maynot be a plug and play set up but the sub sounds 100 times better then it did using the stock terminals. Better response and the box sounds like it has a better seal then the stock terminals. Short of it, if your an audiophile get better terminals or buy a better box if you want all your available power to make it to your subwoofer.

Great Entry Level Subs

September 23, 2017

The following review is for P1S4-12, which is a part of the bundle you are viewing.

I got these for my friend that wanted a budget system, i built a ported box to the reccomend volume tuned to 34 hertz and i hooked them on my jl 500 to test them out before he picked them up and they have great sq actually for entry level, very boomy and nice sounding and they werent even broke in, i played rap and some rock and metal threw them to test their range and i was impressed. When i hooked up his system it made me laugh because you could hear him cruising from a couple blocks away and it would shake the windows on my house alil bit when he drove by and all he had was a cheap hifonics amp. For entry level id say these subs are worth every penny and could probably be priced higher for the quality you get, i own the p3 model myself and you can tell the quality rockford puts in their product's is legit whether its their cheap stuff or higher end stuff.

September 2, 2017

The following review is for MDFS12, which is a part of the bundle you are viewing.

Received this box with the purchase of a sub. Box is made well, although I did add some silicone to the seams. Carpet seams are well concealed and feels of good quality. The edges that overhang make the box easy to pick up and move. Additionally, the box comes with polyfill already installed which is nice if needed.

The terminal plug that comes with it was not so good. The plastic is thin and the whole in the box was a bit larger than the terminal plug. Also, it had an odor to it but that was alleviated by letting it air out for a few days.

The box looks good, is compact for tight spaces, and has a good sound.
However, there is one major flaw. The box smells awful because of the glue or wood that was used to build it. I've had it for 3 months and wish I could return it because it makes my car smell so bad. I had hoped the odor would go away but it hasn't.

If you're on a budget but still want a good product, look no further. These retail for $120. That's how much they are on Rockfords website and at all the audio shops around me.

The following review is for MDFS12, which is a part of the bundle you are viewing.

For the price, this little box cannot be beat IMO. To buy the materials and make one yourself will cost about what this box costs already made and shipped. The box is very sturdy and the brass terminals are really nice. It is a little prefab that I used for a Boss Phantom 12" subwoofer and a Boss Riot 1100w amp attached on the side. It was sufficient for adding a little bump to a stock Honda Accord stereo. I tried to put a Rockford Fosgate 12" P3, but it would not fit without shaving some material around the opening. It is a nice little sealed box.

The following review is for P1S4-12, which is a part of the bundle you are viewing.

I got a pair of these to replace my old pair of kicker comp 12s and they've exceeded my expectations. Paired with the r500x1d amp they blow the kickers out the water. They're in my explorer in a ported box (1.6 cu ft/chamber). The bass makes my rear view mirror point down but that's one of those good problems. And, as always, great shipping/service from sonicelectronix.

Well built 3/4" MDF box. You'd be hard pressed to build one for $40. 1 cubic foot sealed 12 box, not a whole lot you could do to change it. I'm happy with it.

The following review is for MDFS12, which is a part of the bundle you are viewing.

I had received this item and the baffle was partially separated from the frame structure and one one side of the baffle was not nailed down completely and caused a crack in the baffle in that area, I WOULD make sure these are checked before shipping out to customers as the damage does not appear to be due to handling in the shipping process but actually damage from the manufacturer. I do like the style, look, and overall appearance in general :) I am very happy with Sonic electronix so do not let this scenario deter anyone.

The following review is for P1S4-12, which is a part of the bundle you are viewing.

These subs are very nice, and have a clean bass response. For the price, I was not expecting the quality and capability of the subs. I'm running two in parallel @ 2 ohms with a 500 watt RMS Kenwood amp and they are simply outrageous! I have been involved in electronics for over 20 years, and with proper air space in your enclosure, and electronic configuration, you will be amazed.

Perfect box for IDQ12

February 29, 2016

The following review is for MDFS12, which is a part of the bundle you are viewing.

I was told IDQ12s should be in 1 cu. ft. boxes so this is what I got it. Came with Polyfill already in there. My one gripe is that I couldn't use t-nuts on this as the lip is just too small for that. Also, having the Polyfill glued where it is made it difficult to solder the speaker wire and drill holes. Should have shipped the Polyfill but not glued it in.

The following review is for MDFS12, which is a part of the bundle you are viewing.

I ordered this box for my Rockford Fosgate P3D2-12. It is well built and makes my sub sound great. Bass is deep and tight. The sub dropped right in, hole was perfect. The Rockford trim ring is kind of oversized, but fits this box front baffle with room to spare. The black carpet is ok, it's more like fabric or felt. The only thing I didn't like was that the picture on Sonic's website did not show a big ugly oval BELVA logo on the left hand top corner. they should update their picture. For $39.99 it's a good deal.

Love this sub

January 18, 2016

The following review is for P1S4-12, which is a part of the bundle you are viewing.

It took a while to get it set to the levels I wanted but that was due to my amp. I absolutely love the tight and powerful bass this thing produces. I find myself listening to more bass-intensive music than I used to just to hear this thing hit.

I am in Canada and I ended up paying a lot more for the sub due to the terrible exchange rate, but the performance makes me have no regrets at all.
