Sound

Quality

[This review was collected as part of a promotion.] This ported sub enclosure is exactly what my 12 inch sundown needed. my previousenclosurewasa bit to small so my woofer was not even close to what it sounds like now! The truck bed liner finish is super tough and looks awesome in my ride. It handles the bass with such clarity, I can finally feel those low notes rumble. My whole car is vibrating in the best way possible, and the sound quality is way better than I expected. If you're looking to upgrade your sound, you absolutely need to check this out.

[This review was collected as part of a promotion.] best store boughtn sub box ive ever gotten sounds great and takes a beating with a 12" power acoustic bamf with a 2500 watt power acoustic mono amp very nice highly recommend

best store boughtn bsub box

[This review was collected as part of a promotion.] I had it in a normal sub box and it sounded good but once I upgraded to the Q Bomb box it made a huge difference. I highly recommend it because it increases the quality ten fold by just switching the sub box and it's built with great quality.

The Best Box

[This review was collected as part of a promotion.] showed up on time. havent installed yet. waiting on amp to get here!

[This review was collected as part of a promotion.] This subwoofer box is a very nice quality. It is sturdy and looks/feels well made. It has a textured exterior, not the normal carpet like exterior other boxes have. The only downside is that it has a weird odor when I first took it out of the shipping box but that went away after about a day.

Nice quality

[This review was collected as part of a promotion.] My subs knock 4x as hard!! Now it's time to upgrade my subwoofers! I'm still a newb when it comes to fine tuning and maximizing my car's audio system, but that's nothing a little research won't solve!

There's only one downside to this enclosure. I had to cut the sub openings to fit my 12s. Manufacturers defects is easily customizable with a few tools and little know how. 👌
It's pretty difficult to find well built prefab enclosures . Sturdy, well designed boxes are often custom built!!

Well done 👍 QBOMB!!

❤❤❤❤❤❤❤

[This review was collected as part of a promotion.] This box works absolutely perfect! Amplifies the sound times 5 of my last box for speakers… built quality and sturdy can seem to scratch it. Very heavy duty and an excellent product. I can not get over how much the sound of my speakers have improved with just THIS box. I recommend this speaker box to anyone looking, you will not regret it!!!

Quality & sounds excellent

[This review was collected as part of a promotion.] This speaker box is really good quality. It's pretty heavy but that's a good thing. I'm excited to get a speaker for it to see how it will sound. It's pretty deep so I think that will help with its base!

Solid

[This review was collected as part of a promotion.] I was so excited to get to review the QBOMB12TB Single 12" Triangle Ported Car Audio Subwoofer. I've never owned one of my own lol its got some weight to it, 29 lbs, it's not cheap. But man oh man I love it!! Good sound, doesn't rattle at all!!

Pretty hefty!

[This review was collected as part of a promotion.] This is a very well built box. A bit large if you are going to need room in your trunk for anything else. Fits all brands my favorite thing is how sturdy the box it. This will not let me post so I am not sure what else to post it is a box for a speaker and is well built nice sound but is very large so if you have a small car it will not fit

Well built but large
