You can do that with the REL Storm which has independent High Level (neutrik speaker connection from amp) and Low level (RCA from AVR). However, other subwoffer manufacturers usually do not offer independent High and Low level inputs, so without knowing the sub you are replacing the REL with, it is hard to give an answer/advise.
Subwoofer hook up
I have a pretty basic question but I keep getting different answers from people. I have an AVR for movies and an integrated amp with a home theater bypass for when I listen to music. I am looking to replace my REL Storm III with a new subwoofer. The Storm uses a "Neutrik" connector which may be proprietary to REL. It connects to the subwoofer directly from the speaker outputs on the amp. A new subwoofer will not use this connector and I have the option of connecting it via the AVR or via the pre-outs of the amp. Which is correct. I want to listen to music without turning on the AVR (but obviously using the sub) and I need the AVR when watching movies. I really don't want multiple cables and switching devices as some have also suggested.
Thanks
