decent box

The following review is for 1SV12G, which is a part of the bundle you are viewing.

i bought this box for the newest alpine type r.... lets say it sounded decent but not good enough for me, i have had many sound systems and this didnt sound so good with the type r..... if your decide to get a type r id go with a 3.0 cu ft box tuned 32-38hrtz for the best deep loud sound quality

Great Solid Box

The following review is for 1SV12G, which is a part of the bundle you are viewing.

This box is built very well. It's perfectly tuned for the Alpine SWR-1243D Type-R that I also got from Sonic Electronix. The SPL of this combo is ridiculous in the trunk of my '09 Civic Si Sedan, and it leaves more than 3/4" of my trunk space left for other junk. Definitely recommend. With a set of banana plugs also ordered, I still only spent less than $225 which includes the price of shipping for these three items. Speaking of which, I ordered in the early hours of Tuesday (switching over from Monday) and I got the these three items delivered to my door by 11AM Wednesday! There's no way you can find a better deal than that! Now all I need for this combo is some serious Dynamat to keep everything from rattling apart.

Great Box!

The following review is for 1SV12G, which is a part of the bundle you are viewing.

This is a nice box for the price. I normally build my own boxes but I didn't have much extra time and it is too cold out to build one anyways, so I bought this one and I'm sure glad I did. Realistically to buy a sheet of MDF, spray adhesive, bottle of wood glue, nails, and carpet costs about the same as this box and it is already made. Sure it is prefab, but its a very good prefab enclosure. This is real 3/4 inch mdf and the port is tuned pretty low too. I would guess like 34-36 Hz or so. Very solid construction and rounded off port on the inside. Carpet looks great. Terminals are nice too, although they are plastic fasteners, they will hold up just fine. I have a Phoenix Gold rsdc in this box and it slams! I can feel the bass pounding my chest. If you want a nice loud box, this is the box you want. Exceeded my expectations by far!

Not correct box volume

The following review is for 1SV12G, which is a part of the bundle you are viewing.

The box is advertised to have 1.8 cubic feet of volume. It's not, the actual volume when taking into the account of the wood thickness and the ports is 1.3 cubic foot. Plus when you add a sub in it that will also take up some volume so you can count on 1.1-1.25 cubic feet with a sub mounted. The 1.8 cubic foot might be true if their talking about total volume of the outside but that is compleatly irrelevant. The only volume that is important is the inside of the box. And yes the difference between 1.8 and 1.3 is a lot and will make a difference

Bela Sub Box 1st 12 box

The following review is for 1SV12G, which is a part of the bundle you are viewing.

The box is built great, sturdy. I didn't pay attention to the overall dimensions the box is bigger than your average 12" box.
So if your looking to put this box in your car make sure you pay attention to the dimensions. But if your building a subwoofer for home or small club this box will do the job.

Great box

The following review is for 1SV12G, which is a part of the bundle you are viewing.

I put an Audiobahn Alum12X in it with a 200 watt RMS amp. I had to widen the hole a little to get it to fit. It is nice and loud. I put it in the back of my Honda Element so the port fires under the rear seat toward the driver seat. For the cost it cant be beat. It would have taken me hours to put one together. What a time saver. This is the first box I have ever purchased. I usually just make my own.

Good Box for Cheap

The following review is for 1SV12G, which is a part of the bundle you are viewing.

I needed a box for a C2 Audio Threatcon 4 subwoofer. C2 cuggests a box near 2 cubic feet tuned to 35 hz. This one is tuned to 36 as a I recall so it's pretty close. It's nicely constructed. Wish that it were slanted so that I could put it up against the rear seat of my car and that it were tuned a bit lower. For 35 bucks I couldn't build it for less.

I bought this to go with my orion xtr pro. it makes the deeps better mids louder and highs annoying.

Other than that i am very pleased with this product. Sonic Electronix never fails me! I recieved it in three days from KY to WI!

1SV12

The following review is for 1SV12G, which is a part of the bundle you are viewing.

I bought this box for an Alpine Type R 12. I usually build all my own ported boxes but I decided to save some time and buy this one. The box is built from quality 3/4" MDF, the carpet looks great, and the seams are well caulked. What you really should know when buying this box, it is around 1.5 cubic feet net, and tuned to around 35hz. A little small for most 12's in vented applications, but the 35hz tuning was a pleasant surprise. Most prefab boxes I've seen are tuned >40hz and can't quite hit the low notes. Overall, definitely a great value and a decent design.

its pretty loud but tends to sound kind of sloppy at some notes. if your new in the audio game i would get it but i wouldnt recommend it. if you want to save a little money id go with a sealed 1.0. on the other hand if you want crazy loudness id go with a building your own ported box or you can find a good prefab tuned at 32-38 hz. but im happy with it but soon to change box.

I bought this box because it was a lot bigger than the previous box I was using. I have a Pioneer Premier TSW3001-D2 in this box and it still needs more than 1.8 cu ft to show its true potential.

Bought it six months ago to house an Adire Brahma 12" (old-school). I needed 3/4" MDF and around 2sq.ft., ported... Even with shipping it was about half the price of buying a similar box locally, because all my local shops are rip-offs...Sonic can't be beat for price!

So far, everything is great! Only thing that's failing is the window trim on my Pathfinder. X)

Good Sub for price

The following review is for TN12-04, which is a part of the bundle you are viewing.

I would recommend this sub if you're on a budget like i was. For the price these subs can't be beat, but if you like deep powerful bass that you can feel, then these aren't the subs for you. I really can't say much though because i'm powering 2 of them with a Autotek 2 channel class AB amp that only gives the subs 125wrms each. All in all its an okay sub for now.

Bought this box and put a Pioneer Champion pro series 12" in it. Only pushing about 400 watts to the 600 watt Pioneer, but sounds nice and clean. Hits the low notes well. I really like the durable gray carpet, (doesn't tear and get dirty as fast as other black boxes I've had in the past). Box is well built and I like that it has pre-filled walls inside.

good beginner subs

The following review is for TN12-04, which is a part of the bundle you are viewing.

I've owned these subs for about 9 months now. They have lasted great through the abuse. Ive had this sub on 3 amps (dont buy kenwood amps), and in two different boxes, one in old lexus, and the new ported one in my ranger. From the beginning i was overpowering these subs by 50 rms a piece. Now, they are being run by a hifonics 1000.d amp at 2 ohms. so in short do these sound good on 750rms, No they really dont, i have to turn my radio to -2 with the gain all the way down on the amp. But i have to say Ive played these subs for at least an hour a day for the past 9 months driving back and forth to school at a excessive level and they still sound very good although they dont want to handle some frequencies now probably my fault though.

Conclussion: great beginner sub but if you want to go to the next level you cant go wrong with re-audio's se series at least that's what ill be upgrading to.

The following review is for TN12-04, which is a part of the bundle you are viewing.

This speaker is one of the best subwoofers ever made. I wont quote spl's or power handling statistics or any other such specification. I will point to the fact that this this speaker has remain virtually unchanged for 25, yes, twenty five years. In fact, I bought my first terminators in 1989. I have purchased at least 20 of these subs from 8-18 inches. The woofer has a natural tone and can accurately reproduce a wide range of bass frequencies. And yes, they can pound out 35Hz notes all day long. You can get maximum spl at around 200 watts rms, but even at 100 watts you can still pound the pavement, so you wont need a huge amp. Box size is very important for this sub. It is good for both ported and sealed boxes, as well as bandpass applications.
The only drawback is that the box size required is larger than a lot of speakers on the market. But in today's economy, this is the best value for your hard earned buck. 25 years proves it.

Bangin

The following review is for TN12-04, which is a part of the bundle you are viewing.

This little 12 surprised me. I had a kenwood 12 and this terminator made the Kenwood look bad. I have this sub on a 200 watt pioneer amp and it pushes it to the max. doesnt take many watts to push this sub. i have it in a 2 cubic feet sealed box and it rattles my 1996 Grand Cherokee.

awesome box

The following review is for 1SV12G, which is a part of the bundle you are viewing.

I have a cerwin Vega vmax that I've had in a homemade sealed box for years. It sounded great or so I thought. So I bought this box because I wanted my sub to get louder and wow what a difference. I could not believe what it did for my sub. I didn't change a thing but the box and it slams so hard u can feel it in your body. Could not be happier with this box. Appears to be good quality, mine came with a metal belva name badge at top left of box. They even painted the inside of the port black. Long story short lol, get this box.

Nice Box.

The following review is for 1SV12G, which is a part of the bundle you are viewing.

Well built box. I like the durable black carpet lining. Holds up well and doesn't tear easily like other boxes I've had. Check how much room you have in your trunk because it has a good amount of cubic space. I still have plenty of room in my 07 Honda Accord. Love that it's pre-filled. Have a pioneer 12" champion series sub inside and pairs up nicely with this box. Sounds clean and the lows hit nice.

Mtx is great

The following review is for TN12-04, which is a part of the bundle you are viewing.

This isnt the loudest sub mtx makes. But for this price range of a 12" sub, this is one of the best. Mtx audio takes pride in their audio and builds it for durability as well as quality. So you can plan on any mtx product to last as long as you want it to. And Sonic has the best prices around.

The following review is for TN12-04, which is a part of the bundle you are viewing.

I bought this at a bundle with a 350w Kenwood amp from sonicelectronix. when i first put them in it hit pretty hard and put out some good clean bass but after only a month of bumpin around it started to have this ugly crackling sound at higher frequencies... wont be getting another one of these. maybe i just pushed it too hard being that it is only a 400 watt sub, even though it was only getting 150w RMS. Ehh.

The following review is for TN12-04, which is a part of the bundle you are viewing.

I was looking for a sub to replace the blown Cerwin Vega in a home theater powered sub I came into. This had the right size, screw holes, wattage and resistance to replace it. It has been fantastic and adds a new level of acoustics to my system. MTX is fantastic, at any price, even the less-expensive end.

FORGET THE RE SUBS

The following review is for 1SV12G, which is a part of the bundle you are viewing.

I've used this same sub box for 4 different brands of subwoofers and they all fit perfectly. This is a GREAT prefab box UNLESS you're wanting to use an RE sub. I bought this box with the RE Sxx and the basket is bigger than the opening of the box, so it won't work without modifications. And the only reason to buy a prefab box is not having to go through the hassle of making modifications. So it's a GREAT box, will be the best prefab you'll find for this price, just DON'T buy it if you're wanting to use an RE subwoofer.

Unbeatable

The following review is for TN12-04, which is a part of the bundle you are viewing.

Back in 1988 I worked at a stereo shop in New Jersey. A co worker built a rear deck in an Audi to hold 4- 12 inch woofers. He tried several brands that just didn't work. When he installed MTX it was exactly what he wanted. The sound was superb. Since then, I was hooked on MTX.
They are simply unbeatable.

Good box, was looking for something tuned a little lower.

The following review is for 1SV12G, which is a part of the bundle you are viewing.

Well built box for the coin. I did cut out the polyfil just so the port was clear, but left the rest in. It's got a good universal sound and is a lot more pronounced than the sealed box I had before. I have a 12" NVX VCW dual 4 ohm, bridged down to 2 ohm running a Hifonics Brutus 1000.1D
At max I am getting 700 watts RMS, but probably less. The sub is broken in properly and sounds great in the box, but would hit harder with another 300-500 watts RMS. I have my subsonic filter set to about 25HZ. I think the sub plays a little lower than the box is tuned for, not sure, but I think the lows could be better if the box was tuned lower for the particular sub I picked.. NVX tech recommended 2.25 cu. ft. @ 30 HZ. I will be building a new box when I can and tune it closer to 30HZ with a bigger amp. Like I said, this gets me by fine and I have no complaints!

Very nice budget enclosure

The following review is for 1SV12G, which is a part of the bundle you are viewing.

Been running an Alpine tye R in a sealed box for a while and have been OK with it. I have tried this 12 in a couple of other prefab vented boxes and sound quality was terrible. One box was similar in size to this but was tuned way too high and was nothing but boom. The other box was much bigger and tuned to around 32 hertz and was a little better but had absolutely no upper bass and an overly pronounced low bass impact.(very uneven response even after much time spent on setting adjustments) With only a day of listening to this particular enclosure, I have to say it's much more musical and really surprised me. It's blending with my components much better and has the advantage over the sealed box of digging into the very low bass with more authority. I'm hesitant at this time to say it's actually sounding "better" than the sealed box but at this price point you can't go wrong here. Construction is good overall and my box had no cosmetic flaws at all. My recommendation is, if you want a relatively smooth sounding vented enclosure that won't break the bank and looks real nice then this one's for you. Really, at this price point it's a steal and I highly recommend.

Quality > price, must buy!

The following review is for 1SV12G, which is a part of the bundle you are viewing.

I bought this for my nephews new civic. He has a kicker CVX that requires 1.8-2.5 cu ft of airspace. I purchased it through sonixelectronics eBay page for 44 w free shipping. Pairs with the sub and matching 300w kicker amp it produces 42hz of clean clear bass. The beauty of ported boxes is that you can get clean low punchy bass with minimal wattage (assuming you make sure your speaker is wired correctly so the resistance matches what your amp can push efficiently). Look up the wiring diagram for your speaker and amp then match the lowest stable ohm possible. Matching the ohms resistance is more important than just getting the most wattage and your system will last longer and endure less stress. Ok now back to the box. It comes carpeted in either black or dark grey and comes with a nice layer of insulation inside which helps produce the low clear bass and the knock behind it. It also comes with a removable manufacturer tag if you don't like the look. The box has really nice terminals that accept banana plugs which I highly recommend, not only do they look nice they make the connections easier. Overall the quality and value of this box far outweighs the cost. I really couldn't get over how nice it was for the price and when I install systems where only one speaker is involved I am now recommending this box if they do not want or cannot afford a custom box. You won't be disappointed with this box, & for any reason you don't like it send it right back to them.

I purchased this box for my friend. He has a 1st Generation Alpine Type R 12" subwoofer on 300 watts and his system honestly scared me because it was that loud. He seemed very happy when I got this for his birthday, and it makes me happy too. Very fast shipping and easy to install. Loved the cotton inside the box as it helps up the cubic feet inside for the sub to operate in. 5 stars.

This enclosure is made extremely well. It made my NVX VSW124 sound amazing. It looks nice and will turn any subwoofer install into a professional looking setup. I’d buy this or another Belva enclosure and non enclosed subwoofers over a powered or non powered pre-made setup any time. Buy you sub, an amp that meets your subwoofer’s RMS, and the appropriate Belva enclosure, and be amazed. Amazed at not just the sound, but how much you saved over a pre-made setup.

These aren't bad sub. I think the 150 RMS is underrated by about a 100 watts. These are a beginners sub obviously. Good for rap R&B techno and things along that line but if you listen to metal and you want to hear the definition in the fast bass drum kick, then these aren't the best choice, they are a little sloppy.
