Make DPL sound like 5.1

I posted this to the bass list but I thought it was highly relevant to the
Lexicon DC-1 group, especially to all you 7.1 channel folks.
Logic 7 and seven speakers is awesome, but you can do this even one better.

I have the Audio Control Phase Coupled Activator series 3 and I think
it sounds great. Set it to the lower 35-70Hz sampling range for 17-35Hz
synthesis and you have more bass than you know what to do with. Tone
down the mixing gain to a sensible level (about 9 o'clock) and walla,
you have some bottom octave bass that wasn't their before.
Add in a Lexicon DC-1 with its Logic 7 algorithm and now you can make
Dolby Prologic movies sound like 5.1 !!!
A subharmonic synthesizer needs to be used in moderation, like the
Fifth Element DVD with its 5.1 track is bass ridiculous to begin with.
Adding some bottom octave to that is just silly. Actually I think the
movie might of been processed through a subharmonic synth once when
it was made, it has somethings that are tell-tail subharmonic synth
signs. Guess its time to break out that FFT again.

After some spectrum watching I and not seeing any doubled lower harmonics
I must now say I was mistaken, The Fifth Element was NOT pre-processed with a
sub harmonic synthesizer, it just has a lot a real heavy bass.
