Ivan, why not a passive multiamp setup on these boxes?
We may try to do a passive mid/high-high to reduce the amp count. We have not tried to do develope a crossover for that section yet-but Tom's hunch is that we won't be able to get the phase where we would like. But I question how much of a difference it would make around 8Khz. Not as bad as down in the heart of the vocal range.
I also doubt that we could get the mids to mid/high alignment correct without a phase shift. But we haven't looked at that either-yet
There is no way to align the 18" woofers to the rest of the ranges that are mounted on the horn-due to the physical path length.
The origional idea was to only have the JH90 as a powered cabinet. But the shear pressures inside the cabinet were causing the amplifiers to fail-actually cracking the circuit board paths.
So that idea was scraped, and the use of the DSP with a preset is the standard setup now.
For what it is worth, Josh from Lab Gruppen is coming to the shop this week to work with me to develope settings for the Lab amps. So that will be another option.
So more options may be available in the future.
