Southwest Audio Fest, March 21-23 2025
- Thread starter ehowarth
- Start date
Good exhibitor list for a regional show. I was hoping though it was in Arizona or something given the "Southwest" designation.
A company I'm associated with will be showing a new loudspeaker at the 2025 Southwest Audio Fest. If you were there last year, we'll be in the big first-floor room that had Stenheims last year.
You can see the new speaker at the link @ehowarth posted, second-from-the-top and on the left.
@amirm their weight is prohibitive so they are not candidates for your Klippel system, unfortunately.

Congrats Duke! Very cool, I know you have been working on this for a while. Best of luck at the show, I fully expect the speakers to be excellent
… as to Klippel, I am sure Erin would love to take a go at them, he seems to have no issue measuring larger designs

Thanks!
The specifics are different from whatever I talked with you about a couple of years ago, but the concept is similar: Prosound drivers and a custom horn; good pattern control down to the Shroeder frequency region (though not a cardioid); and an adjustable rear-firing driver so that the reflection field can be addressed independent of the direct sound. Separate subwoofers required.

Outside of separate subs required, I am a fan of this design
… you know my opinion, major proponent of full range mains (PLUS multi-subs)

The room we're showing in is a ballroom, estimated internal volume 28,000 to 32,000 cubic feet (we don't know the actual height of the ceiling).
Last year the speakers in that room, medium/small floorstanders, were unable to provide a decent bottom two octaves. The "owner" of the room wanted to make sure he didn't have that problem this year. My contact in the prosound subwoofer world, Bill Bescript of Sonofinity, visited the room last year and was quite confident his subs would be up to the task. You can see subs to the outside of the Illusio main speakers in this photo:
Actually those two subs, when stacked with the openings in the center of the stack (so the bottom unit would be inverted), constitute a single "PAQ 30" sub. It transports in two pieces, each of which weighs about 320 pounds, and as you can see the two pieces can be used un-stacked like we are doing.
The subs are DSP-controlled and driven by a 12,000 watt amp (on a 240-volt line). They easily pressurize that big room. In fact we had to deliberately roll off the low end south of 20 Hz because when we played a recording which contained infrasonic information, we heard disturbingly-loud rattling coming from multiple locations in the ceiling.
Of course I understand the aesthetic objections to using subs, but sometimes the situation calls for an enormous amount of output which realistically can only be delivered by big subs, whose output can shaped as needed via DSP.
Incidentally Bill is the engineer who produced the thick carbon-fiber horns used in the main speakers; that horn project is how we met.

Thanks! You might need to turn on captioning because Jason's microphone does not pick up Hans very well when he steps back a bit while explaining the extreme toe-in.
