The ADS 710s, 810s, and 910s from the early 80 had terrific metal grills. There is NO way for a kid to access the drivers thru those. Floor stand them or mate them to the low-profile, tilted ADS stands or the Auralex SpeakerDudes stands and you'd have a fairly kid-proof setup.
Those ADS speakers sounded damn good and can be purchased dirt cheap nowadays...
