Super disappointed

Box came very damaged with improper placement of glue. Sides dented and splitting apart.

Got this for my Rockford T1, gave me excellent bass, at times it's a bit much but better too much than not enough! Would recommend this box to anyone wanting big bass! The only downside was that the hole for the sub wasn't big enough, not a problem though as I have a router.

Solid built box

This is a well made box and provides an overall good sound for use of one subwoofer. 2.5 cubic foot of air space is dead on for the JBL sub I'm using and it sounds good. Tuned kinda high but I was able to adjust everything to my liking. Great build quality and made up good.

They made it good!

Bought an enclosure a few weeks back and the enclosure came with about 4 corners smashed up! Was wondering why they do not ship the enclosures with at least Styrofoam corners to protect them? I ordered this enclosure for the convenience not the money or I’d of went down 45 minutes from my house to grab an enclosure from the local stereo shop. Knowing I would have to wait to get a shipping label take it down to FedEx and have it shipped out and waited another week. I have read a lot of reviews about the same situations with people receiving store credit or the same value in trade but no refund, so instead of dealing with the situation I just considered it a loss I was going to fix it up, so a few days ago I received an email stating I was going to get a full refund and that my account was going to be reimbursed! Wow was not expecting that. I want to say thank you Natasha and the Sonic team! I will be shopping with you guys again!!

I love this box

I have 2 boxes behind my seat In my 2001 Chevy Silverado with 2 Rockford Fosgate TO 12s on a 10,0000-watt power acoustic vertigo and it hit so hard you can hear me from a mile away literally! Great box I do recommend it !!!

Broke apart after about a week

I put an American bass xfl 1222 in this box. Sounded good. But after a week of use it was already coming apart at the corner opposite the subwoofer. It was fluttering air. I will say this was in a boat so it got bounced around a lot. It was secured to the floor though. Either way. I wouldn't recommend it for any application where it would get bounced around much such as a boat.
