Tim,
I've written pretty extensively on the Velodyne SMS-1 sub controller. You may want to search these threads and check it out. Unless you are using DD series Velodyne subs, this device is absolutely transformative. It may take some work, but a decent sub (or 2 or 3) with an SMS-1 will get smooth bass response in even a difficult room (like mine) and seamless crossover to your mains, to boot.
Good Luck
Marty
