Atrend Bbox 12SVSC Single Vented 12 Inch Subwoofer Box - Premium Subwoofer Box Improves Audio Quality, Sound & Bass - Car Subwoofer Boxes & Enclosures with Nickel Finish Terminals

If you do not give this 5 star, you have no idea what it takes to make a box and wrap it in fabric. I was very happy with the box. The 1 inch front is crazy amazing. If I made this by going to Home Depot I would have to buy an entire 4x8 sheet. That is $54. The material to wrap it would be min $20. Then I need to design it and spend 4 hrs cutting the 4x8 and building the box in July heat. I am a master carpenter and to build this one time would cost in materials 100% of the price I paid...plus my labor and errors and mistakes and my felt wrap would never have the factory tight look and feel..so the value says buy this box. The mfg is making an insanely strong build and it looks great and it serves a single purpose which is keep the woofer stable and immobile which this does for less than you can make it at home...this is a huge buy signal. The complaints...read them...troll lazy complaints which are not functional complaints that impact the sound or look or value...you can spend twice more on the same box or not...thus ends the lessons.

This is a reallly good box for the price, can't go wrong. As another reviewer said, the description is a little misleading as part of the construction is 3/4" mdf (as advertised) and part is only 1/2" mdf. I sprayed the interior with plastidip to sort of thicken it up and prevent vibration, although I'm not sure if that was necessary, it does seem well built and glued together. Porting frequency seems a tad high (see UPDATE below), maybe 45 or 50hz or even higher? ...but it's easy to lower the porting frequency with a wadded up old tshirt or a pool noodle as another reviewer suggested. In an automotive application it might be low enough, for home theater or dnb or hiphop shows maybe experiment with a pool noodle in the port *grin*. Overall, this is a fantastic box, well built, pretty compact, a real steal for under $80 shipped. ~~~ Note you will need a drill bit for speaker holes, some screws for mounting, some wire to connect your sub to the terminal. UPDATE: Confirmed the porting frequency is much too high, added it at a show to a KV2 dual 15 (one of the best sub setups) and this was literally canceling out the lowest notes of the KV2. We finally shut off this sub. BUT, that is an easy fix, partially obstruct the port with something like a pool noodle OR if you are near a wall place this sub an inch or way from the wall facing the wall. This will effectively lower the porting frequency and it won't cancel out the 35 hertz notes from your other speakers. Still great for the money! editagain: In my pic I'm using "Allstar - ALL14100 Black 3' Roll Bar Padding" to mostly obstruct the ports and the porting frequency after doing that is about 31 hertz. MMM mmmmmm (I'm guessing it was 45 or 50 hz before that, much much too high)

The box is built with the upmost care and quality. I don't have the best subwoofer in the box, but it's doing well and I'm completely satisfied.

If you have a sub laying around that needs a box then YOU NEED THIS. Comes with every thing you need and the components feel like quality materials. The sound is also shakes the earth. Installed with an infinity 1250w sub ran off a Jensen 1000w amp at running bridged 4ohm 500w setting, the box amplifies the low ends of all kinds of music and it seriously changed the way my audio system sounds entirely, plus if you’re a 99-04 mustang owner this is the one box that will perfectly fit the convertible model if you can’t find anything this worked perfectly. If 6 stars was an option I would rate it 6 stars! :) PERFECT VALUE FOR THE MONEY

4 stars because a little damage during shipping see pic other than that box seems sturdy and heavy.

Good box

Well made vox

As other reviewers have stated. The wires are too short to reach the speaker for installation. They might be long enough with the speaker installed, if you somehow could pass your hand through the solid wall too attached to the speaker. Otherwise I don't know who thought it was a good idea to make them that short. The wires will need to be extended. The hole was big enough to fit my Kicker CompRT 8" but as others have stated the whole is rather small and might not fit all eight inch subwoofers. Fit and finish is passable at best. The plaque in the corner of mine was misaligned with the adhesive holding it on. Not an issue as I took it off anyway. The upholstery was peeling up from the adhesive around the vent port. I was able to solve that with some spray adhesive. The acoustics are pretty good though. At least for my setup and the type of music I'm listening to. Overall for those of us who don't have the ability to make our own it is acceptable. But I'm sure there are better on the market. I wouldn't necessarily recommend it.

What a tight beautifull low sound this box gave out when married with 12" Alpine speaker.

Great

EXCELENTE CALIDAD SE ESCUCHAN LOS GRAVES INCREIBLES ELPRECIO MAS QUE JUSTO PARA TAN BUENA CALIDAD LO PIDES HOY Y TE LLEGA AL DIA SIGUIENTE EXCELENTE SERVICIO Y PUNTUALIDAD

I was gonna build my own box, but for the price of a saw blade, and a sheet of 3/4" MDF this was cheaper! I am blown away by the quality too. It is nailed accuratly, and all the joints are glued. It is extremely strong, can be used for many purposes. On top of that the carpetting is extremely neat, there is no excess anywhere. The connections are basically free at this price, and installed very well. The ported box is a benefit to my budget set up, this box ties it nicely. Very happy

As described
