well arent you just full of info jason...thanks

Hmm, ok then. So if the speaker had a rating of 94db, it would sound 3x louder then the 88db one?

my friend has it in his lol dont flame me, his 2000 Hatchback focus, their loud, im gonna get two of the duals, mount one to both sides of trunk, so base speaker glass face towards each other and buyin 2 amps for the subs, is this stuff hard to do?

No, it would be four times as loud. Decibels are logarithmic, and a 3dB increase is a 100% increase (or 50% reduction if you're going downward). Therefore, since 91dB is twice as loud as 88dB, and 94dB is twice as loud as 91dB, 94dB is four times louder than 88dB. However, because human hearing has such a high dynamic range and is also logarithmic in perception, doubling or even quadrupling the acoustical power may or may not sound like a major difference in some cases.

And low sensitivity isnt always a bad thing. Some high power speakers have low sensitivity as a side effect of better power handling and other bennificial factors. I also try to look at the Fs, the Xmax and the Mms of a speaker aside from power handling, i dont really pay much attention to sensitivity

i agree with u that u have to spend money to get ur moneys worth

Ok. You know a lot, even if your username suggests otherwise.

Nah, everything I learn in school goes in one ear and out my butt.

Thats a good one!
