Will the speaker sound be compromised, or is it even possible to hook-up a 4 ohm speaker to a receiver output of 8 ohms?

Is it possible to send 4 ohms to front speakers and 8 ohms to the sub and/or surrounds with a normal AV Receiver? Thanks
Well, yes or maybe
You can hook up an 4 Ohm speaker to that receiver but, depending on its capability, the receiver may not be able to drive it very loud, or maybe not even at a good comfortable level. All depends on the receiver.
Yes, you can hook up an 8 ohm rear and 4 ohm mains with the same qualification.
Most/many subs are powered, have their own built in amps, so that would not enter the capability issue above.
