Smoove Posted September 14, 2015 Report Share Posted September 14, 2015 my dealer had recommended 3-3.5 per driver for a more spl based daily box. Ill be pushing them with around 8-9k daily. i always thought for the most part go a little bit smaller on airspace for better control at higher power levels. If that not correct? Also i was told the thicker baffle help focus the rearward sound wave. there has to be a reason big spl guys build thick baffles.... thicker walls are more of a requirement for taller walls. your only doing 2 subs with a center port. the center port adds support for each sub. in a wall 3 subs or more, there is more area to allow flew. 2 Team Fi 15's v1 2 DD M5's 970amps of Alt 6th order blowthroughThe truck Blowthrough build : http://www.stevemeadedesigns.com/board/topic/155555-smooves-1996-chevy-ext-cab-c1500-slow-build/The 350z build : http://www.stevemeadedesigns.com/board/topic/170694-smooves-2003-nissan-350z/ My FB page https://www.facebook.com/pages/Smooves-Car-Audio-and-performance/719746144805343 Team Fi Audio http://www.ficaraudio.com/ Link to comment Share on other sites More sharing options...
Aaron Tuck TBA Posted September 14, 2015 Author Report Share Posted September 14, 2015 I'm no designer, but don't DD like tons of port area? Like, tons? I wouldn't trade port area for box space here though, you're already on the small side. 3 net per sounds awfully small. i havent traded anything for port area. i first decided the largest face i can fit in the opening. put 2 15s in it then seen how big of a port i could fit. so 36.5 wide and 2 15.5 o.d. subs leaves me with 5.5" wide port. 2000 Cavalier 4 doorXS D925XS D2400XS D31004 runs of 1/0 Mechman 270 2 DD 9515js Link to comment Share on other sites More sharing options...

Use good wood and it shouldn't be a problem. That may be a lot of weight, but the edges of the box are so close to the sub cutout the weight only has to be supported over a very small distance. If the walls of the box were a foot away from the sub cutout things might be different.

Aaron Tuck TBA Posted September 14, 2015 Author Report Share Posted September 14, 2015 I picked up 2 sheets of birch I plan to build with. Weight of the box shouldn't be much of an issue. 2000 Cavalier 4 doorXS D925XS D2400XS D31004 runs of 1/0 Mechman 270 2 DD 9515js Link to comment Share on other sites More sharing options...
