SVS PB10-ISD, Hsu VTF-2 mk II, or the Velodyne (DPS or DLS) are all great choices. If you could stretch to $600, then you could step-up to a 12" version from each mfg, and also include the Outlaw LFM-1.

Also, this is in a four-sub setup, oriented into a 2-sub configuration with 2 subs stacked at the mid point of opposing walls (front and rear).

Are you saying that you want to buy 4 $500 subs or that you want to add one $500 sub to three existing subs?
If you want 4 $500 subs I would recommend buying 2 $1000 subs instead.
