Another one to consider is M J Acoustics. British made, sealed, down firing sub. They look small and are small, but they pack a hell of a punch. I heard the PRO 50 MKII which is only 120W MOSFET power and 10" driver. The box is about 11" cube. For that small of a sub it was quite impressive. That model sells for about $800 CA. The Pro 55 MKI is a 12" driver and 150W amp, sells for $1500 CA.

I own an EP500 and I am happy with it, although it is not as musical as I hoped it would be, it really shines in movies.

My 2 cents..
