Great value

I got the box built, installed my sub and it is delivering the thump like a champ. Great time saver having the drawings and specs. Everything got cut all at once and fit together perfectly.

Stout n quality design Brng your sub to life like nvr b4 1000% Improvement beat all expectations.

Clear ez to read prints, awesome having all the specific paneel cuts on 1 page. Every piece including the corner trim & bracing specs are laid out in detail, this box really brought out the most of my current sub, even tho the specs don't quite match the Kicker Comp12 i droppd in it, it still was a night & day improvement over the previous smaller box-which is my fault not CT's. The design is spec'd for the CT Sounds Tropo xl 12, which I finally just ordered along with an amp, Meso 6.5" component set for the front doors, Meso 6.5" midrange woofers for the rear. So I'll be 100% CT Sounds system by this time next week!! Cant wait, will update my thoughts on all those products, I'm expecting 5 stars all the way. CT fricking rocks!
