Ritteri, thanks for your suggestions regarding recordings with ultra-low frequency tones. I will truly check them out. My experience has been that most redbook CDs trying to articulate low bass simply double the 40 Hz tone (+3-4dB) and allow room resonance to do the rest. It is well known that you do not have to produce the fundamental tone (spectral pitch) in order to "hear" it (virtual pitch). In fact the difference between spectral and virtual pitch may explain why we naturally want to boost the bass and attenuate the treble in order to obtain "full-range". A pure spectral 20 Hz tone is extremely hard to produce acoustically (think 32 foot diapason) and though fairly easy to synthesize electronically even more rarely recorded as such. Why bother when a 40 Hz tone overloaded into a boosted subwoofer "sounds" like the real thing?
