what are some really efficient subs at a reasonable price (~150 each). i know the infinity perfects are like 94dbs but what are some others?

The Infinities are really only about 88-89db, NOT 94. They rate their sensitivity not only with 2.83V (2w) instead of 1w for the 4ohm subs, but also in-car rather than in infinite space (how sensitivity should be rated).

is that ALL infinity subs? And by efficient, you mean they do not take a lot of power get going?

I don't know about all of their subs. But I know the Perfects for a fact rate their sensitivity in that very unorthodox manor, making them appear to have a higher sensitivity than they really should.

if you could spare maybe an extra 100 you could pick up a used IDmax, or a new RL-p 12.

cerwin vega! mainly, the old vega series.

is it better to have a lower number or higher number?

higher.

You could get a pair like mine for 150$ They handle 400 watts each and sound pretty **** good.

Depends. Hoffman's Iron Law....you can only have two of the following three:

1) Low frequency extension

2) Small enclosure

3) High efficiency

So, you can see that, by default, as you increase sensitivity you must either increase enclosure size or decrease your low frequency extension. No way around it.

Hopefully you can see why most car audio subwoofers have such low efficiency figures. For car audio, we want good low frequency extension out of a small package....and therefore, efficiency must inherently suffer.

So, higher sensitivity isn't necessarily or inherently always a good thing //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Depends on your goals and application

Memphis PR's are pretty efficent.

image dynamics IDQ is one of the better [and with a good pricerange] low frequency, and efficent sub in a relativly small enclosure.

x2! I run 1 15" Vega and the sub is very Loud & Low running at rms (500w)!
