yeh thats it! i have room to spare also
ive just been decided how to build a sub for DD2012 (12" car audio sub) ... it hax 10x the power handling so perhaps ~10db more output... 132db with 250watts if im lucky...i was hoping for 142db
im just wondering if i shud rush build it,just for spl comp,or not...
its on Feb 8th,i can buy the woofer off the guy im borrowing off if i want it afterwards too! i jsut need to find 250watts!
you can estimate
105db eff
20db amp
13db car gain
=138db.....
my car booms at 50-55hz by about 7db relative to 80hz,so i thought id load the cone there and burp it around that freq as to save the woofer from moving too far and BL compression? also im unsure of exact xmax so this helps too.
Im estimating im ~8db down from expected and hoped performance with current 8" with 25watt rms Pe and 3.5mm xmax!
Cheers!
