Hi,
Has anybody came across this little driver from Eminence;
http://www.parts-express.com/eminence-8-high-excursion-dvc-subwoofer-4-ohm-per-coil--290-4008
At first sight i would say you could make a very efficient low freq. horn with this.
I am looking for a little driver that can achieve a decent 20hz loaded from a corner i an living.

I have a pair at home. Going to build a BR sub for my sons car. They seem well made, but I havent heard them yet.
why start so small? The horn mouth will have to be the same size if you start with an 8" or an 18", but the horn with the 8" throat will have to be much longer if the expansion rate is kept fixed.
But either way, a 20Hz front loaded horn (as opposed to maybe a tapped horn) is going to be huge, is your room?

If you can relax your size and price range I think you will have more joy with this:
No, that's not going to happen. Even a cornerhorn drops
like a rock below 35 Hz. That woofer is so wrong for a horn I
just don't know where to begin!.
This driver models just fine in a horn, but with its 33Hz Fs a 30Hz LF corner is a better choice than 20Hz. Besides, the 150w thermal rating and relatively small Vd would be limiting when going lower than that.
Could this work for a "small" slot loaded sub?

Sure, but then it wouldn't be a high efficiency speaker.
