Can a McIntosh MC7205 handle Polk Audio RTi A9’s?

If you want to hear the speakers playing the 120w per channel is fine.....But if you wanna feeel the music and be THERE at the event you will need more power, these speakers are rated at 90db sensitivity and I suspect even with their nominal 8ohm rating these will suck power! I recommend at least 300-400 watts per channel driving 8ohms.
ALSO, you have a multi channel amp that could be configured in a different way combining channels to output more power to two channels instead of 5. I owned a MC7104 4- channel amp and I could easily set it up for 2 channel and the power would go from 100wx4 to 300wx2 so check it out.

Yes just watch out for that combined channel power it can be a lot more then you think because of the way the speakers are hooked up the amp might see a lower ohm, most Mac amps are not going to be affected by this in the least bit but your speakers will and if they are rated around 100w or less you could overdrive them at higher volume levels.
