I think that trick works best when the speaker system can get down to within one octave of full bass response, so down to below 80Hz for sure, and you have to be careful to not apply enough distortion that everything sounds worse. You may also need something like a speaker crossover, where only frequencies below the bass cutoff of the speaker system are sent to the distortion circuit, then the output of that goes through a high pass to get rid of the low frequencies which cannot be reproduced by the speaker, and the harmonics added back in to the original source to create the illusion. I'm not sure where you are located, does your locale have a saying regarding attempting to make a high quality result when starting from limited quality source materials? Perhaps you are finding the limits of such a small system. http://www.dictionary.com/browse/can-t-make-a-silk-purse-out-of-a-sow-s-ear -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
