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.

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.

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 :/

Box sounds good but the port is a bit too big. The hole for the sub was too small for mine but thats to be expected for a prebuilt. Con the fabric by the port is already flopping in the wind and the outer port wall or the back of the box has a crack in it but that's a shipping problem over all I like the box but I wouldn't put a powerful sub in it because there is no inner support and the sub might break the box due to box flex

Bought this speaker box for one of cars and very happy with the quality thank you
