Any speaker you place there will have the same results. If the child gets used to the speakers and environment there, then they eventually disappear into the landscape of the room. You have to say "No". You can play with the child near the area to show them the speakers and equipment are part of the landscape, do to speak. As soon as the child veers off into touching or going to the direction of the speakers, then you say no and resume playing in the vicinity.
I had two stand mount speakers in my living room since my 2 kids' birth. Of course they were curious but a quick "NO" and resume elsewhere/redirect eventually worked. The speakers and equipment just became invisible into the room at some point.
If you replace with a $500 or $50,000 speaker, that won't change the child's behavior.
Bith you and your wife need to be on the same page with this.
Good luck
