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!

Sounds good!

Built it exactly like it shows. Probably should have tweaked it just a bit but it still sounds good. Have the old model strato 12" in it and the specs don't quite match up but I'm still impressed. It's stout as can be too. The directions don't show anything about the fancy looking front but that has nothing to do with the sound of it.
