   It is true that the amplifier's load can destroy the amplifier should that load be a short circuit, or too low an impedance, or its capacitance or inductance compromises the amplifier's stability.

Therefore, an amplifier ought to be designed with these things taken into consideration.

The output inductor protects against some degree of capacitive short/overload.

The Zobel network compensates for the loss of loading.

And the phase and gain margins must not reduce to, or go beyond zero (or even approach it) when the amplifier is subjected to known difficulties.

Thermal conditions are easily detected simply by touch, and if a particular load results in the heatsink/casework getting hotter than you feeling comfortable with, then maybe something is amiss.

Much of the worry comes about by manufacturers who omit safeguards on the premise that their circuit is "perfect" (which circuits seldom are) or "it sounds better" without them.

Fools rush in where angels fear to tread, and I'd rather fear than look a fool. Having said that, the man who never made a mistake has yet to be born.

	Thank you for the replies. I was considering multi-way horizontally and vertically with the same driver for a larger image size (potentially) and even less mechanical excursion for the bass. Don't need more power and no need to reduce dispersion. I'll have to try it; cardboard boxes are cheap.
