Well, in between loads of laundry and fixing a friend's shower door, I finished building the long promised MkIV crossovers, and modifying the test box, so I can evaulate the design using the Vifa XT25 tweeter.
We discussed the XT25 almost to death on this thread, including a lot about philosophy of design and measurement.
Right now, I'm getting ready to hook up the monitor to the test speaker test computer, and see how it looks. What's quite pleasing, is that I've been listening to one channel on the test box, and I suspect I'm finally getting a little better at this computer modeling and cossover development stuff, because it *sounds* like I've been tweaking it for a few days or more- very nice balance, great mids, very easy to listen to. Crossover point is 1.25 kHz, yeah, we're pushing the envelope for an XT25, but then the acoustical slope is 48 dB/octave Linkwitz-Riley.
More to come, soon. I've got my fingers crossed on this one. The actual proto boxes will use a slightly revised panel layout, based on simulations using BDS. At any rate, it will be the LAST version of this speaker I do- I think. At least for now. Too many other projects in the wings, like Arvo Pärt.
Bye for now-
