They are the Velodyne DLS-3750R. They now have been replaced by the EQ-Max series.

I got them at Future Shop here in Canada last summer when they were clearing them out. Being the current models, the EQ-Max are still quite expensive.

They may not be considered to be the ultimate in subs by the HT fanatics out there; however, they make my house shake & rattle nicely when required & they sound clean with music. If you are going for smaller subs under 12", then I think that at least 2 would be the best option for better sound dispersion.
