Bought it last week. Terminal cup was not sealed hardly at all, and one of the posts were loose, but to have a properly sealed enclosure you have to seal the terminal yourself anyways. So after tightening the post, which was a breeze, and sealing the terminal cuwtt35824 and mounting surface for the sub all with multipurpose caulk and letting it sit for a day or so, its completely air tight. Seems fine, havent hooked it up yet but there shouldnt be an issue. Worth the price for sure, and very sexy with a nice black sub too!

Ordered this box from Sonic along with a Boston G5 12". This box is very sturdy and the carpet was excellent. The terminals are great as well. I didn't use any polyfill and it sounded pretty good. This box overall was excellent and I have nothing bad to say about it. I even spun around once and the box went flying across my trunk and no damage was done.

Great box, great price!

I wasn't expecting much from this box after I ordered it this summer. I wanted to experiment with this box to see how well it performs for how cheap it is. Once I received it and started inspecting, I noticed it's not true to size. You WILL have to shave the diameter of the slot so your subwoofer could fit in perfectly. It runs a little smaller than most 1.0 cu. in. boxes. So after my modifications with an electric saw/sander the subwoofer was finally ready to fit in. I played my favorite songs and the bass is accurate and very tight. A little too tight for my liking. I've had it for half a year already and so far there are no other problems with it. This is a temporary enclosure as I look for a higher quality & bigger cu. in. box to permanently replace it. All in all the box is average and it does it's job. So the saying "You get what you pay for" actually applies to this.

Pros:
Does it's job
Very tight bass
Carpet lining matches most OEM grey carpet
Lightweight

Cons:
Small cutout hole
Requires slight modifications
Low caulking sealant
No free shipping

Tips:
Use an electric saw and sander to modify the diameter.
Tighten the terminal cup and gold posts.

This is a finely constructed sealed single sub-box!.I was actually surprised by the quality for this amazing price. Every piece is quality from the carpet on the box to the gold-plated connections. I believe that Sonic competes with any on-line retailer out there. I will be using Sonic Electronix for all of my audio and video needs... Two thumbs up!
