I’ve been real busy with work so this is the first time I’ve had to catch up on this thread. Thank you all for your suggestions. Update:
Just repositioned my mid-highs to more closely align with both the vertical and time axis of the TLs. WAY BIG improvement very largely affected my raising the altitude of the HF drivers so they’re slightly above ear level.
I need to remeasure the system. This time instead of relying on FFT and impulse exclusively I will look at both pulse and triangle waveforms as well which should help reveal transient response issues when differentially viewed on a scope.
Re-examining the current filtration reveals a suspicious boost applied around the digital x-over point, most likely a phase issue since Fourier addition should require a cut there and not a boost.
Next I plan to re-EQ the system so all filtration happens below 400Hz and there is no time delay applied. If that further improves things I’ll design a 2 or 3 way that will be time aligned with the TLs and will work from 150 or 200 Hz on up.
Currently looking at SEAS MCA15RCY (to be rolled off below 150 or 200Hz and up to 2k or so) to couple with Dynaudio D28 up to 4.5k then use either my 3/4 Ti or Vifa tweeters on up. The Markaudios would likely get smoked pretty quickly due to low power handling (30w) coupled with fairly low efficiency (~88dB spl @ 1w.)
I plan to try to keep the passive filtration to 1st order BW and non-inductive resistors as needed to eliminate x-over induced phase error.
All digital filtration will be on the low-end exclusively so as to completely eliminate any digital delay blurring of the image.
Another more expensive option would be use the TLs from 25 to 200 Hz, the SEAS from 200 to 4k (angled at 20°,) and Eton 26HD3s on up.
