Atmos: Speaker/Amp selection

[Maggot]

Hello.....I wanted to ask a question regarding speaker/amp selection. I recently bought, as an Atmos test with my old Marantz 7009, one pair of Micca mb42x speakers, which state they range from 4-8 ohms and handle 75W. I am wondering if I made a mistake in that they might overheat the height amp in the receiver?

Also, if it turns out I like what I hear with even just the .2 Atmos and decide to get a second pair, I would need to buy an external amp coming from the pre-out as I have my front towers biamped from the receiver. Now I was considering getting the Marantz MM7025, which has a lot of power, but I don't go crazy on volume, si I don't think I'd blow the Miccas, but again.....if they have a range of 4-8 ohms, would this be an issue for the MM7025?


Would I be better off getting a more beefy height speaker that is 8 ohms and a little more power handling like say a Polk Monitor 40 series II at 150W into 8ohms? Or even their TS15?

Or do I go with some lesser wattage "integrated amp"?

I do plan to get the newer Marantz SR7013 receiver for DTS X in a few months.

Any thoughts are appreciated.

Been using this for years for atmos speakers. Works well and once everything is powered on, they turn themselves on/off automatically. They don’t cost that much and are reliable.
