dsp for audio - speaker excursion ?

Archived from groups: rec.audio.tech (More info?)

I was wondering whether anyone here had any recommendations for methods
of improving speaker audio performance with the use of a DSP (digital
signal processor). I have heard of different methods of improving the
system.

I have heard that you can make measurements of the loudspeaker
excursion limits and use these parameters to control a dsp compressor
to get a lot of performance and volume out of the speakers without the
risk of overdriving them at low frequencies. I imagine that this would
allow you to boost the low end a bit where the speaker starts to drop
off -- without risk of overdriving the speaker.

Has anyone experimented with some methods like this? I already have a
setup where I drive my speakers from a dsp and it knows what volume and
all of that I'm at, so it seems like with these measurements there
could be a significant improvement.

Thanks!

Do you mean something like this?

I would love to hear them, but they are way beyond my budget.
