This box is very solid and heavy. The port is grooved into the box makes it that much more solid.

My only complaint is the wire terminals. They are very very cheap. I was tightening one down and just a little bit extra beyond barely tight and the bottom ripped thru the plastic. I ended up not even using the wire terminals.

Sub sounds great. Paired this box with a 15" Alpine Type R. Hits lows and midbass 20Hz to 80Hz great, then it quiets down as the bass goes up.

I bought this box and put a audiobahn flame q in to is the first two weeks I had it the port broke loose
after I put some more screws in to it I never had any more trouble

well its a little small for a vented 15 but for 45 bucks its well worth it... just stuff it was like 2 pounds of poly and it will slam

This box is very sturdy. I carry things often and it's in and out of my jeep frequently and it's held up to the abuse. The sound quality is a good 7/10 but the construction proves to be somewhat resonant with my setup. A cv vmax on 600rms is probably beyond the capabilities of this box. A sub with 3-400 rms would likely be more suited.

box is solid and clean it's huge though so any small/mid sized car owners might wanna take a second to measure (i ended up taking my back seat out to make this install easier) but other than that nice box

the terminal ring might need some extra glue mine slipped out when i pull the wire on accident ( ps DONT tighten the wire teriminals with a wrench because it's a pita to get it off and you might end up breaking it)

Good price on a well built box. Makes my 15" RE Audio SE-x subwoofer knock!

the box is very well built and a lot larger then i thought it would be. definitely a good buy if your to lazy to make one like me :)

I have this box housing a Rockford Fosgate P3D215 and i have heard this sub in a sealed box and the port makes all the difference. This box is durable and it also looks good in black.

This is a really good box for only being about $50

Very well built; solid construction. Made with the best material (MDF) for speaker boxes

good durable speaker box.

This is a strong, big , heavy box that can handle alot of power from a subwoofer. However, it is a little pricey, but you get what you pay for and I'm not disappointed with it a all.

these boxes are pretty good not going to lie every car ive owned i put my subs in these boxes they bump hard and last these expensive boxes with the plexi- glass rattle im a huge fan of these boxes

Overall some of the best boxes i've ever owned there enormous and very, very well built. I've had these hooked up for a month now with no signs of problem. i have 2 05 kicker CVRs in these boxes in the back of my s10 blazer and they pound ridiculous, the only downfall is that there is no room left back there for anything. i would recommend these to anyone.

this box I put a power acoustic mofo in it and the bass rattled your vocal chords excellent box I suggest it to anybody

I purchased this box a few months back box came in great condition with zero flaws and had never been previously used.
-The only problem i have had with this box is that the carpet was never secured well on the inside edges of the port and the air from my sub has blown the carpet loose so it just kinda flops around now. this isnt something that happened over time it happened 4 days after i started using the box.
