Alex1234 Posted May 28, 2014 Report Share Posted May 28, 2014 Ok how important are the subwoofer sizes when it comes to playing loud? lets say you have a room for a maximum 200liters or (7 cubic) box and wanted the highest SPL possible on a 200liters box money was no option and you could choose from on of thes setups: 1 DD9918 on 2500rms or 4 DD9908 on 10000rms what would play loudest in teori? one dd9918 has more cone area but four dd9908 has more rms wattage Link to comment Share on other sites More sharing options...
Phaeton Posted May 28, 2014 Report Share Posted May 28, 2014 I dont know what a DD9918 or a DD9908 is, but im assuming its a 18" woofer and 4 8" woofers. I had 4 lanzar 15's and they were loud, Then i got a single fi sp4 18 and its waaay louder. on the same amount of watts. But it also depends on what music you listen to. I wouldn't buy a 18 if i just listen to speed metal. And i wouldn't buy a 8" of i just listened to dubstep. The 18 will play lower and the eights will play higher. 1997 subaru legacy outback Four 15's in a almost wall Rockford Fosgate t2500-1bdcp Rockford Fosgate T400-4 on tweets Rockford Fosgate T400-4 on highs Rockford Fosgate T400-2 on midrange Rockford Fosgate T400-2 on midbass Optima Yellow top batteries 270A Singer alt (working on a bracket for a second) Lots of Second Skin Link to comment Share on other sites More sharing options...

CleanSierra Posted May 28, 2014 Report Share Posted May 28, 2014 Impossible to answer your question. Far too many variables. I didn't know that DD made a 99 series in an 8" sub. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
CleanSierra Posted May 28, 2014 Report Share Posted May 28, 2014 I just checked, they don't. A 4" coil will not fit in 8"(or any 8") basket. You'd have no room left for a spider. So you have some numbers messed up, I'm not sure which. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
