preamplifier after preamplifier?

2nd advantage of this solution, you always need to deliver signal to subs as early as possible since sub drivers are not fast in reaction. So your speakers receive the signal little later than subs. Result is matching phase of both drivers (normal speakers and subs) if sub signal arrives at your ears too early use subs’s delay or phase knobs to adjust.

works flawlessly.

any solution with dsp or 2nd preamp cannot beat above.

Enjou the music…

Didn't Elizabeth have three preamps daisy-chained together at one point?

I wrestled with this for years. Bought a dbx drive rack 360 and love it. Very versatile. Check it out. Control all speaker volumes, delay, parametric/graphic eq-the list goes on and on. 

We suggest keeping the system as simple as possible, with one preamp, our choice is the miniDSP SHD, it would integrate like this:

Here is the functional block diagram,  this allows for full control over all crossover slopes and frequencies, channel levels and delays.  Most importantly, Dirac Live room correction.

Thank you for posting this suggestion. This is a really intriguing solution. I have been looking for something that will provide better subwoofer integration and possibly room correction. The McIntosh MEN 200 does something similar, but it is significantly more expensive and it doesn't provide this level of adjustment.
