Thread: Sub debate

Personalty I think JL has the best sound quality $ for $. You buy lower end speakers you get lower end/outdated equipment. I have 2 L7 12's sound great alot of how subs sounds not only has to do with what kind of sub but also what size/kind of enclosure you use. I have my box tuned for sq not spl and I think it sounds good considering. Plus ported boxes sound like **** b/c of the "lag" you hear from the air going in and out of ports. I dont think the JL's would sound worse. I just dont think they would hit as hard as the L7 got to remember the square design of the L7/L5 means a 10" sub moves as much air as a 12" sub. Id like to trade both of my L7's for a W7 but that ant gunna happen anytime soon lol

lol you can only go so big with ports you have to take into account how big of a box your sub can handle and yes you hear airflow ask any installer. Its air flow in and out of the port which makes the sound "lag" and unless your going for spl u need a sealed box period. I know I have a ported box for my L7'S built to kicker specs for SPL and I have a box I built myself to kicker specs for SQ and my homemade box sounds better then the pro built ported. If u don't think ported boxes sound like **** for SQ then you need to turn your subs down and your hearing aids up.

Not really. "SQ" is based on a pre-determined frequency response that an INDIVIDUAL prefers and then finding a way to install and manage your car audio components to match that curve.

Any sub can sound however you prefer in pretty much any enclosure you design. Aperiodic is a hybrid idea for ported/sealed and considered(by those who have listened) to be one of the better enclosures to use. However, good luck trying to master that.

Bottom line...there's a lot of guess work in car audio but your goals can be realized if some deep thought, research, and good fabrication are used in your installation.

Ported is tougher to get right but as a whole, this guy has it right. I think ported adds more variables than I care to deal with so I just use sealed
