Subs without power amps


Which sub would you recommend that does not have a built in amp or cross over?

Thanks

The big VMPS subs are passive and very good, I have one I drive with an Onkyo M-504 amp.
Peter, I believe German Physiks makes one for about $12k.

The good news is you don't need two as they can be used for stereo mode with the two drivers.

-IMO
