This is what grabbed me the first time I read it years ago.
"It does not matter if your speaker does not go down to 31.25 Hz or not. If you are sending low frequency information to the amplifier, the amplifier will make the plate voltage move. If the plate voltage moves, the tube must spend bias current to charge and discharge the primary inductance as well as the actual primary load impedance. If the plate voltage or current "clips" because of low frequency plate excursions, the sound will suffer."
This changed my outlook and I took steps to keep the low frequencies out of my single ended midrange/tweeter amplifier. The sonic results are very positive.
Thank you.
