I have an R&S FSEB that goes down to 20Hz - besides going up to 7GHz,
yay overtones :) but doing audio with it is kind of a pain as the sweep
takes ages. sadly it does not have the FFT filter option installed that
would speed that up.

I guess these days you'd go for a dedicated "audio analyzer" rather than
an SA - or just use a decent audio interface...
