"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, [all] the sound will suffer."
I already bi-amp at 200Hz. My mid speaker doesn't play very well below 200Hz. After reading VS's article I placed a cap (a high pass filter) in series with the input to the SET amp. The sound, all the sound, got much better.
