I agree with Marc, the Advents were a great speaker in their day, but they were very inefficient. I now own some M3s (bought from Marc) and they are much more efficient. To get the same bass response you can always add a subwoofer.

If you are still using the Advents for a while, there is a switch on the back that should be in the extended position. Do that and take off the grills and the sound is much more open.
