Default How concerned should I be about load impedance?

I have come upon a bunch of very well made and well maintained solid-state class A amplifiers (35W/channel into 8 ohms) made in the late 1970s that I would like to use in a multi-amp system to drive low-impedance speaker arrays at very low power levels (I doubt peak levels would ever go far beyond 1 watt, even for the woofers.) These amplifiers are designed (judging from the markings on the amplifiers themselves) to be used with loads ranging from 4 to 16 ohms; however, I estimate that my speaker arrays could have impedances well below 3 ohms. (2.6 - 2.3) Am I just asking for trouble by hooking up such low impedance loads? Or given the miniscule power demands to be placed on the amplifiers, are they likely to tolerate it? THANKS!

Default Load Impedance

At low levels you should have no problems. . .the current demand
will be higher than normal but the amps should still work. Get ready
to keep them cool.
