4 or 8 ohm connection for a 6 ohm speaker?

Bill,


You can try all 3 to find out which you prefer with your speakers. It will not hurt anything.  I would imagine the 4 , or 8 ohm tap would be in your range of preference for your speakers..

Thank you Timo62 for the reply. I have them on the 8 ohm tap at present and will try the 4 ohm tap next. 

Hi Bill, I would suggest the 4 ohm. Please report back your findings the differences.

It makes sense to try the lower tap first, but there definitely have been cases of particular combinations of amp and speaker where the tap a little over the nominal impedance sounds better.  Of course, if you ever look at some measurements, nominal impedance can be a pretty fuzzy term.
