That a very big box. 8 cubic feet after woofer and port displace? I had 2 re SX 15 tune at 37 Hz after woofer and speaker displace in 6. cubic. Burp loud. The re is good for SPL at 35 Hz. Not all sub have to be tune at 40 hz for SPL. Edited November 4, 2008 by Gotloud555 Quote Link to comment Share on other sites More sharing options...

Boon Posted November 6, 2008 Report Share Posted November 6, 2008 There's about 10000 things to consider. What sort of vehicle is this going in? Is it for pure burp SPL or is it meant to be musical? 8 cubes is too big unless you don't have much power. How many watts will they be getting? Quote 10.x volts fo' life!

osixfrontier Posted November 6, 2008 Report Share Posted November 6, 2008 i am currently runnig 2 re sx 15's in a honda civic hatch, my personal best is 148.9, @38hz.... i havent meterd since my upgrades, but im sure its louder now, any way, my box is 8 cubes after all displacement tuned to 33hz with 16 inches of port per cubic foot, its sub up port back.... for pure spl i say 6 cubes after all displacement tune it to 40+ hz with 18-20 inches of port per cube and give it around 6000 watts.,... i am currently running 6000 to ine daily, it doesnt like ti too much it gets warm after 2 songs and starts smelling after 4-5 songs at full tilt....... my setup is daily groundpounder, i drive it everyday too and from work, i listen to it every day...

osixfrontier Posted November 6, 2008 Report Share Posted November 6, 2008 the soundstream xxx6500d? that does not do 6000 T 1 ohm unless you run it a t 16volts.... it does about 4400 at 14volts... the z2 is not a good daily amp..... i would prefer to see the z2lvh or something like that, if you gonna do inter changable ports make one for 40 hz with huge port and the other tuned to 33 hz and 15 per.... that is the lagic number with sx's for daily 15per at 33hz...
