Thanks for your reply 4313B
By the way, I have a miniDSP in the heart of my horn system and I like it. I haven´t had the opportunity to compare it very much with other filters, but it sounds way better than the recent RANE that I had. I like the interface and the ease of changing Xover, PEQ, levels etc. while actually sitting in your couch, instantly getting an idea of the result of the changes you make.

Aww! You should hear my Tannoys with Ti!
Evidently they don't have as many problems with the material as JBL did. I certainly don't feel the need to dump a bunch of aquaplas on them to get them to sound decent.
That Audax dome in the Performance Series didn't need a bucket load of aquaplas on it either.
Which reminds me, I wonder if G.T. was ever able to get the aquaplas off the 476Be's in his Arrays before he sold them. He was going to try soaking them in water for a few days to see if it would loosen up. The 4-inch Be's and Mg's don't seem to need it. I guess that's why Brush Wellman doesn't bother putting it on.
Im sure its just a few month away...I'd like to think that it is the future. It would be nice to have a rack mountable version that one could communicate with wirelessly using their smart phone.
The 475 Ti is another matter I presume?The 4-inch Be's and Mg's don't seem to need it

May be, not only FR response, but also THD would give better answers, is it better single large VHF driver or UHF for over 10kHz.
As JBL shown in their "Technical Notes Volume 1, Number 31 = Progressive TransitionTM (PT) Waveguides" the 2-nd HD is about -26dB on 110dB
equalized sound level, I think the same results were presented in "Technical Note, Volume 1, Number 21 =JBL’s New Optimized Aperture™
Horns and Low Distortion Drivers."
.".............. the basic setup for measuring second harmonic distortion. For these measurements,
the output level at one meter from the diffraction slot of the horn was carefully maintained at 107 dB SPL
through the use of the compressor in the B&K test gear. This level corresponds to 87 dB SPL at 10
meters (33 ft), and thus represents normal application of these horns. The action of the compressor
simulates, on swept sine wave input signals, flat equalization of the system on axis, as would be the
case in real world equalization practice for many applications. The total range of compression was about 15 dB...............
..The JBL 2352/2451 combination is shown ....Again, second harmonic distortion has been raised 20
dB. Here, midband distortion lies below 1 % up to about 2.5 kHz, reaching a value of 3% at about 9 kHz."
