I thought bose speakers work best with their systems.
Seeing how bose doesn't make it easy to find any information (maybe because they don't want you to know) about power handling and other spec's, I would be cautious hooking these speakers up to a regular surround receiver. If you look at the Bose web site all they show are these speakers being connected to the bose subwoofer, which is acting as the amplifier for them, and crossover.
Using a regular receiver, and a sub output to just about any subwoofer, may not produce the ideal results.
Someone else here may have dealt with these speakers and have a different opinion.
We just purchased 5 bose jewel cube speakers. Can anyone provide advise to us as to which powered sub woofer to use with these speakers? We have a Kenwood VR-8070 receiver which includes a sub woofer connection.
