Is it OK to connect only one subwoofer to a 7.2 receiver? Will I “lose” some
sound doing so?
Electronic House says:
Absolutely you can use a 7.2 receiver for 7.1. You will not lose any of the subwoofer’s signal by only using one of the sub outputs, you just won’t be getting benefit of a second subwoofer. A second subwoofer doesn’t necessarily give you more low frequency sound, but it can improve the quality of that sound by delivering it more evenly and cancelling out room resonances. If you’re not ready to add a second sub, buying a receiver that can handle it is a good way of future-proofing your system for later.
