I recommend the M60s.

The reason is this....although there are some amps out there that can handle the M80's 4 ohm load, I prefer a speaker that does not give an amp "something it needs to handle".

The M60s will be great for what you are describing. If You have not read it already, I did a 5 year review in the "Stereo" thread that may help you decide.
