4 or 8 ohm connection for a 6 ohm speaker?


I have a pair of Thiel CS2’s that have a nominal impedance of 6 ohms. My mono blocks have output impedance connections for 4, 8 or 16 ohm speakers. Is it best to connect the speakers to the 4 ohm or 8 ohm connections? 
Thanks for your thoughts.

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.
