Hi Galo,
Just thought I would reply to your amplifier power for the M80. I have these running off a Carver M500t amplifier. The Carver is rated at 250W into 8 ohms. It gives a spec in the operator manual of 350W at 4 ohms at 1kHz.. I use them strictly for music and I rarely go over above 50 W peaks on the VU meters(if you can believe the meters). These speakers are very efficient and I can't imagine driving these speakers with 250W on up. I would imagine they start to break glass or eardrums! Good luck.
