I am going to guess that my FS030 OT are about 250K db down at 1.5M Hz so I don't think it would be an issue for me. Perhaps DBerning amps have some sort of low pass filter on output? My OTs probably serve the same purpose.

I am referring to the effect on hf noise on the voice coil.
The sensitivity of the voice coil to low level signals makes the speaker more "revealing".
My question is, if the HF frequencies outside the audible range are super imposed on the audio signal, wont they deteriorate the sound reproduction in the audio range? Obviously I am not talking Bose!!
