A research assistant here did that last year - recorded his acoustic
measurement sweeps in mp3 format. Had to go back and do it all over
again... Whatever remains of a sweep after deconvolution is just junk.

As to the LF, many small devices such as mobile phones generate bass
by just exciting the miniature speaker at its resonance frequency.
Works well for kick drums etc. You get bass indeed, but nothing like
the original signal.
