[QUOTE="swimfreak26, post: 474641, member: 544365"] Right now i have a 15 ported, in around 2 cubes which is what you're talking about only sealed. Not having been metered I would put my setup right around 140ish. Now something to think about.... The dB scale is logrithmic, Thus a ten dB increase from me, 150, would be 10 times as loud (ten times the pressure), or twice as loud to the human ear. Now add 5 more dB to that, doing about 3 times that pressure....and you're at 30 times the pressure that my sub creates which is at an "ear-hurting" level as it is. 155 is a monumental setup, and I don't see it happening sealed in 2 cubes....maybe ported in 15 cubes with 5 REALLY big amps.
