Valery reported back in 2012 on his DTQWT project.

Hello, I just finished GRT-145 installation. I have put the GRT's into beech cases with small stands. It can be moved and changed the tweeter axis. I used the crossover you recommended last letter. I have to say it is a positive experience. DTQWT sounds much better to my ears. I am going to keep GRT as a part of DTQWT.
Thanks!

Hello Troels
Later i wrote to you about GRT-145 as a super-tweeter for DTQWT. Now i refused to use supertweeters considering that unnecessary. TW-034 gives all we need.
Otherwise we have to search for treble in amps, cables, room, ears etc.
Recently i have installed Hypex FA251.
I chose side panel of DTQWT for the FA251.
For the start i used your program for the Fusion-Bad. Then i made 3 presets with 80 Hz, 100 Hz, 120 Hz points for low-pass filter.
My default preset is 80 Hz point configuration.
Finally i can say that it was easy and gave additional benefits to the sound. With the FA251 I can find the best points for speakers with best mid and treble performance, best transparency and sound stage regardless bass level. And then tune bass easily with Hypex.
Thank you!
