Will the M7100X damage the R-50M?

No. The M7100X is rated for the R-50M's 8 Ω load as it comes.

What impedance setting should I use for the R-50M on the M7100X?

None: the R-50M is 8 Ω, and the M7100X needs no change for it.

Is the M7100X powerful enough for the R-50M?

More than you need. From a seat 2 m away, loud 95 dB movie peaks take about 8 W per speaker, and the M7100X is rated 90 W per channel. Cinema reference level, 105 dB peaks, takes about 80 W.

Does the Klipsch R-50M work with the Monoprice M7100X?

Verdict

Yes

The R-50M is 8 Ω, and the M7100X is rated for speakers down to 4 Ω, so it drives them as is.

Speaker load

8 Ω speaker, rated down to 4 Ω

Power

90 W

More than you need. About 8 W gives 95 dB peaks at 2 m

How to connect them

Connect the M7100X's inputs to the pre-outs of your receiver or processor: a power amplifier has no volume control of its own.
Connect each R-50M to one of the M7100X's channels with speaker wire.

Plan the R-50M and M7100X in your own room.

Draw your room in 3D, place both, and see every connection checked and how loud they play at your seat. Designing is free.
