Very Compact Subwoofer


Anyone have an opinion on the performance of this sub:

Anyone know of other ultra-compact subs; must be 13" square or less,powered.

Thanks!

sunfire subs are 13" cubed, tons of power at over 1000 watts they have a smaller version as well I believe
I see there is also a smaller HSU Research sub; I've got some options now! Thanks, everyone, for the leads!
Douglas_schroeder, are you building it into a cabinet?

I'm very pleased with my Sunfire Super Jr, but it's a dual driver unit, so not an easy install if it's enclosed. Other than that I second the Velodyne Micro-vee series.
