Your speakers are a 94.5dB@2.83V/1m sensitivity wise.
With a minimum impedance modulus of 4.1 Ohms at 135Hz with the rest of the spectrum at 5 Ohm or higher.
They're not voltage hungry and are not current demanding too so 100Watts is enough to send each speaker to 100.2dB peaks from 12 ft away. Meaning for the stereo pair you're getting 103.2dB peaks, 12ft away. That's hearing damage level SPL with 100 watts alone
Your concern should be for your ears not the speaker transducers @hardrocker69
