Will the M7100X damage the DC53?

No. The M7100X is rated for the DC53's 6 Ω load as it comes.

What impedance setting should I use for the DC53 on the M7100X?

None: the DC53 is 6 Ω, and the M7100X needs no change for it.

Is the M7100X powerful enough for the DC53?

More than you need. From a seat 2 m away, loud 95 dB movie peaks take about 23 W per speaker, and the M7100X is rated 90 W per channel. Cinema reference level, 105 dB peaks, takes about 225 W.

Does the ELAC DC53 work with the Monoprice M7100X?

Verdict

Yes

The DC53 is 6 Ω, and the M7100X is rated for speakers down to 4 Ω, so it drives them as is.

Speaker load

6 Ω speaker, rated down to 4 Ω

Power

90 W

More than you need. About 23 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 DC53 to one of the M7100X's channels with speaker wire.

Plan the DC53 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.
