What is your receiver set to?? 6 or 8 ohms?
I just searched the manual for my Receiver which is a
Pioneer VSX-1018AH-K and it says it recommends using 8 ohm speakers and if you want to run 6 ohm you have to set the receiver to 6 ohms.

I trust your advice RickF...no offense -- but i would love to hear from more people before i place my order.

The VP-150 is a very efficient speaker and if i run it at a 8 ohms instead of 6 will this affect the characteristics of this speaker?
