Speaker Suitable for Baby/Children - Wall Mount

I have a baby that is just crawling and about to walk and another one on the way (an unexpected blessing!!!). I am in the process of selling all my equipment and build a simple system. My preference is to get the speakers out of arms reach, i.e. wall mount.

I like the Magnepan MMGW but these speakers do not cover the full Frequency Range (only goes from 100-16kHz) and therefore requiring a flooring standing subwoofer - this will not work. The MC1 seems like a better option. The addition of the CC3 and another pair MC1 would be a good HT option. The initial 2-channel setup would be driven by a NAD C320BEE integrated amp (would convert to NAD T743 or higher if we decide to go with HT later).

Simply put:
1 - What "kid friendly" speakers have worked out well for you and what have you used to drive it?
2 - If you have any experience or thoughts on the Magnepan MMGW, MMGC, MC1, or CC3 then I would love to hear it. How would you drive these speakers? Would the NAD C320BEE work out?

I am trying to build a system with consideration for safety (to both baby and equipment), economics, and sound quality. I have always had the bad "upgrade itch" but this system will have to say for a long time. We do not listen to music very load so do not need a lot of power or bass. We mainly listen to classical, classic rock, and some jazz.

This system would be for our family room which has vaulted ceilings and approx. 30ft x 45ft (not sure - will have to measure).

Thanks for your time and thoughts.
