Bbox Single Vented 12 Inch Subwoofer Enclosure - SPL-Tuned Single Car Subwoofer Boxes & Enclosures - Premium Subwoofer Box Improves Audio Quality, Sound & Bass - Nickel Finish Terminals

Well, if you look at the last two images, you will see where my sub (Toro Force 12) powered by a RF p1000x2 @ 2 ohms, literally ripped itself out of my first box a Qbomb 12 ported. Yeah...never had that happen in my life! I was impressed and upset all at the same time. So after doing some research I found the Atrend 12" SPL box. It was close to optimal size ( I did line the inside with polyfil as you can see in the first two images. This brought it to about 2.5-2.6 cu. ft internally. This box is KILLER! The response is outstanding! I currently have it running the Force 12 however stepped up my amp to the SKAR 2000.1. With the gain at nominal and the head unit setting the sub output to -1 it still kills it! I am more than happy with this box. Now, I did reinforce the walls with screws all the way around (Hey, I like to go the extra mile...) to make sure there were no kind of issues, but honestly, don't even think I needed to. Soundly assembled and the method they use is quite impressive. I am more than satisfied with Atrend and the box they build.

Solid box and sounds good , great customer service , fast shipping !

Had this box for not even 24 hours and already from upgrading to it from the prior enclosure I had, it sounds crystal clear & hits all the notes in a much smoother, crisper sound. The quality of the box seems pretty good! I have it 4/5 stars due to one thing I did notice. One of the nails holding in the piece for the internal port wall was poking thru the wood, but not enough, or in a way to make me worried. The subwoofer cutout is almost spot on. Usually boxes I’ve had in the past will have play and be hard to mount, but this had maybe a total of 1/8” of gap around the sub total between the cutout and the woofer housing. Definitely a plus. Will be updating as time goes on, but if you’re someone curious about this box and wanna pull the trigger on it, I say go for it.

I am pretty satisfied considering the corners are a tiny bit smashed, it's mainly cosmetic crap. However I'm digging the construction of the enclosure, it's solid and caulked very neatly. The carpet on the exterior has been wrapped to 99% perfection. The binding posts are of a low grade quality in my opinion. That can be resolved easily. I'm very certain my 12" 1200 Watt RMS DVC Sundown woofer is gonna love it's new home. I hope this helps in your decision making process...

Well, after reading reviews I decided to take a chance on this box. Terrible idea. I ordered this with a reasonable sub (Alpine Type-R) and after 2 days I hear an absolutely terrible distortion. At first I think I have my amp tuned to high so I take a look, its only about a quarter of the way. Nope, that isn't the issue. I put my hand in front of the port and don't feel any air. I decide to put my hand in and find out that the wood piece that chambers the air out of the port has cracked and is being held by an inch of carpet. Anyways, I strongly recommend just going to your local Stereo shop and just buying a box from them. Never again :/

Very well built awesome box got a 12 inch cerwin vega pro in it and it literally makes it sound lyk 2 subs. I used to have it in the recommended box at 1.50 cu ft slot ported and it was good it was jus loud when i upgraded to this it became louder and also it vibrates my car even more its not just loud to the eardrums you can actually feel it in your chest to your throat. All in all if u got a sub that could jus make it in this because I heard some subs sound like crap in it then this box will do wonders for you. I would highly recommend this box if you dont have the money and resources to do a bigger setup.

I wasn't expecting much from a prefab from Atrend but this box rocks. I have one Alpine Type R 12" with a650 watt rms amp. The difference was night and day! Before I had the Atrend B-box sealed and I thought it was hitting hard but after installing the sub in this box without changing any settings, I could feel my eyes vibrating and everything that wasn't bolted down vibrating around me. My only complaint was that the corners of the box suffered some damage from shipping but no big deal considering. BTW if you have a late model Honda Sedan you are going to have a fun time fitting this bad boy in the trunk! A+++

Well shucks! I just knew this box was the one!! It was delivered in mint condition, fresh out the box its just beautiful. Unfortuntely, even though I read the specs on this box, the port is just tuned too high. My sub is missing too many low notes. Its funny because the notes that are produced are so clean and hit really hard. But without those lows I can't enjoy.......It's a really good box, gonna try to re tune the vent myself hoping I can get some lows. Great product, just not what I was looking for.

Very strong sturdy 12"sub box works as it's attended for. Good carpet no loose corners no carpet overhang. Worth the buy

Best quality

Good sound quality but you can see and feel the box is cheaply made
