[QUOTE="T3mpest, post: 6714558, member: 560148"] no if anything it's lack of actual effeciency. Ultimately cabin gain in a vehicle kicks in at 80hz or thereabout. Most vehicles have at least 20-30 decibels of actual gainfrom 80-40hz or so. Depending on where your specific vehicle falls in thatrange your looking at needing anwywhere between 100-1000x the power on an 80hz tone to match the same decibel reading at lower bass notes. That's why alot of sq setups use sealed subs. They roll off as the bass goes lower to help keep things more flat. A ported enclosure in many cases wont' do that. Car audio really only gets as loud as it does because of the environment your in. Look at home audio with much bigger spaces, if you can hit 140 your golden, that's with big setups costing alot of money to get output that high down to 20hz. In a car, you can do that with some midlevel subs. Expecting any sub to play midbass like it plays subbass isnt' going to happen. WHile the speaker can do it in free space, the cabin gives you too much gain up high to ever make up the difference. [/QUOTE]
