Don't you wish studios had a "bring a friend to work" day ?mastering engineer friend
Yep, as per the link I posted earlier. Kiat Low in Sydney now runs Duntech and follows John's design principals in general. Also another brand called Orpheus... not as big and expensive, but still excellent speakers.Built by the same guy who designed Duntech speakers, I think.

Loudspeaker designer John Dunlavy: By the Numbers...
One of the characteristic traits, I have found, that defines the loudspeaker designer is that they are loners—they seem to avoid one another's company as if on purpose. But if ever you sit down with a designer, all you need to do to open him up is to ask him what he feels to be important in...www.stereophile.com
I owned a pair of Dunlavy MTM type speakers with two 5" drivers and a tweeter in the center. Forgot the model number. I think they were a vented design. They had absolutely no bass at all. Otherwise, they were okay. I owned a pair of 2-way speakers with a six-inch driver, and that trounced the Dunlavys, bass-wise.Anybody know anything about these? A mastering engineer friend swears by them (I think he uses SC-Vs), but I can't say I've ever heard them. What's their claim to fame?
I've listened to these speakers before and was very, very impressed;I just get what I think sounds good.
That was under sighted subjective conditions, though.Built by the same guy who designed Duntech speakers, I think. I had a very serious interest in buying a pair of SC IV's which became Stereophile's Speaker of the Year in 1994, so I went to Underground Sound in Memphis and auditioned them. They were in the same room with Aerial Acoustic 10t's which I had never heard of at the time and two Avalon speakers which were their top of the line, and next one down. To keep it short, the Dunlavy's were the worst speaker in the room, the top of the line Avalon's were the best, and then the next in line Avalon's and the Aerials sounded nearly identical to my ears. I later saw Stereophile's measurements for both speakers, and, guess what, they measured very nearly identically as well.
Anyway, the Aerials sounded killer. I bought them in early 1995, and they wound up being reviewed by Wes Phillips later that year and became Stereophile's Speaker of the Year. I kept them from 1995 to 2011, and thought they were terrific. Hearing the Dunlavy's next to them made me realize the whole "time coherent-linear phase-first order crossovers" thing was way overrated.
BTW, to not do them a disservice, the SC IV's did sound really good, it was just that the other three speakers sounded so much better.

The time/phase is the big deal with them, as was thiel.
You can probably hear it as different, but not necessarily as right or wrong, or even better or worse.
If it was best way to (6db crossover, aligned centers) design them, the best sounding speakers (or even monitors) would all be 6db time/phase, but fir or some mixed slopes can pass a square wave (spica).
You would hear the tweeter "straining" as it is working hard an octave below crossover point versus a 12-24db crossover.
We usually (audibly) zoom in on resonances, distortion, dispersion, etc.
And I don't listen to live acoustic music, so I have no reference.
I just get what I think sounds good.
"Hearing the Dunlavy's next to them made me realize the whole "time coherent-linear phase-first order crossovers" thing was way overrated."
from phoenixdogfan above in post 8 above really hits the nail on the head.
I want the whole set,along with the Halcros .Oh god I want those
Probably SC-I. All DAL and Duntech speakers that John Dunlavy designed used sealed enclosures, stepped baffles, and 1st-order crossovers.I owned a pair of Dunlavy MTM type speakers with two 5" drivers and a tweeter in the center.
