Home Speaker Asylum

General speaker questions for audio and home theater.

Re: This is silly...

That's all very interesting but the question is not the audibility of ultrasonic frequencies but whether or not SACD playback benefits from 50khz-capable speakers. I say no and it is easy enough to test. First, listen to an SACD on a 50khz-capable audio system, Then, listen the same SACD on the same system with the addition of a quality low-pass filter with a 20khz cut-off. If the presence or absence of the filter is undetectable when listen to CD or LP sources, I predict that it will be undetectable when listening to SACD sources.
