Dual 15's ported

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

Great design

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
