Dual 15 Inch Ported Subwoofer Box Design

Great design. I run 2 audiopipe bdx15d2's with 2 audiopipe 1800w amps and she F'N slams. Well worth 75-100 bucks and they sold the cut sheet,exploded view,all measurements. Couldn't be easier. Mines tuned to 30-31 hz and rattling my truck loose. Might have to see what they can do for 4-14's next

I have bought box build designs off line before and thought if the person selling had been dropped on their head. $5 for quality online blueprint/design. Most ppl charge $80+ for some totally useless designs.
100% real. I've built 2 dual 15" boxes stacked from these. They are the best design/online blueprints yet, can print them out, enlarge. So happy I happened upon ctsounds.com truly amazing quality

i just wanted a little bass in my daily driver. it started off with 2 10's. then i wanted a little deeper bass and thats when my buddy told me about CT Sounds. I ended up getting the strato 12". Was really pleased with it and then i started wanting to go a little more. ordered the Strato 15" and was amazed. I drive an extended cab truck so now i have no back seat, 2 x Strato 15's, 1 x Strato 12", and the other 2 x 10's that i initially started with and 4 amps.. (one for each size subwoofer and one for the component system) Now i plan on getting one more Strato 15 when i get the extra cash and the matching compontent system once they have it back in stock next year. My truck was not supposed to turn into what it has but i cant say im mad. Lol But i know im never buying a different brand of speaker again. Thanks CT Sounds, and ill always recommend your product!

Very good design, haven’t built it yet but will be doing so soon.
