Speaker hook up question.

My tube power amp has hook ups for 4 and 8 ohm speakers. I just noticed my speakers are rated at 6 ohms. I currently am using the 8 ohm leads, is this correct?
Could be. I have usually found the 8ohm taps to be best for most of my speakers, even some 4 ohm ones where the amount of power needed to drive the bass wasn't an issue. My 6 ohm speakers, which have a min impedence of 5 ohms sound much better on 8 ohms. Depends on your speakers and you ears. Try them both - you won't damage anything.
I also own an amp with 4 and 8 ohm taps, and I own speakers rated at 6 ohms. I have found the 4 ohm speaker taps work best in my system. As Newbee said, try them both and decide for yourself.
Hmmm, I was always told to go lower to avoid damaging the amp? I never use the taps whose impedance is higher than my speakers.
