"Hancocks" by Ben S. (Wolf). Drivers: Dayton SIG180-4 and AMTHR-4. Xover: LR6 at 2.2kHz. Scrap wood baffle boards give the speaker a very cool retro type look and feel. The highly polished auto body type finish on the rest of the speaker contrasts well against the gritty looking baffle board. I like it. These will be tough to beat at SDC. I'd give them very high marks for both craftsmanship AND sound quality.
"Fireflys" by Taylor H. This project was a re-build of an old Kenwood LS-622 bookshelf loudspeaker and a Kenwood SW-38HT powered subwoofer. Crossovers, box alignments, and cabinet finishes were modified substantially for improved sound quality and appearance. Here is a link to the PE project gallery for additional information on this project: https://projectgallery.parts-express.com/speaker-projects/fireflys/
The work on these was fantastic. I think he said it was reclaimed 2x4's sliced up into 1/4" veneer, then layed on that 45* chevron pattern. Sounded quite nice as well.👍🏻
"The Defiants" by Keith E. @KEtheredge87 From Keith's brochure: Drivers: Dayton RST28F-4 custom mounted in Visation WG148R waveguide. Dayton RS180-4 woofer. Xover: 6 parts, 1630Hz LR2 electrical, 4th order acoustic. This was Keith's entry into the 2019 InDIYana "Bare Minimum" competition, which limited the xover to 5 parts. This, however, is xover version 2 with an additional 1.5 ohm resistor added to the woofer circuit. The baffle finish is "Electric Blue Python Tolex." The cabinet finish is a heavy figure curly maple veneer, dewaxed shellac, and semi-gloss polyurethane.
"Timekeepers" by Nick S. @ugly_woofer Drivers: Tang Band 25-1719s ceramic done tweeter, Dayton RS125P midrange, and RSS210HF-4 woofer. F3: 27Hz. Beautiful, highly polished automotive finish. I can't remember hearing these; I must have been out of the room when they played. I don't have any pics of Nick's presentation or the playback arrangement.
Sorry, but I was out of the room when the below two speakers were presented. Since they did not have tent cards, I am unable to post any info on these speakers. If you know who brought these, please let me know the speaker name, designer, drivers, xover, etc., and I will edit this post later. Thanks .
"Hegemon IV" by Meredith C. @mcargill Drivers: Dayton RS100 widebander, Onkyo W2301G 10" mid-woofer, two 1976 Empire 15" woofers in clamshell isobarik configuration, and a proprietary Ideal Point Source Tweeter. After studying Meredith's binder and watching the presentation video 2 or 3 times, I think I have the basics down. Crossover is a series connected affair with several notches and contour filters. This is a 1.5 type design, so there is no specific crossover frequency between the widebander and the 10 inch woofer. The drivers overlap considerably and are blended together with several series and parallel notch filters to produce an overall smooth response. The speaker is designed as a single monophonic "point" source using a 360 degree horizontal and 120 degree vertical waveguide. The RS100 faces down into a reflector that compresses the sound out the sides into the 360H x 120V waveguide. The 10" midwoofer faces up and compresses its output into the same waveguide through a series of 12 holes. The RS100 and 10" midwoofer compressed outputs into the waveguide are less than 1" apart. Toward the bottom, two 15 inch Empire woofers are mounted in an isobarik clamshell configuration with a slot loaded outlet at the bottom of the enclosure.
"Micro Grand Utopia" by Bill S. (4thtry). Drivers: Bozhen CQ76B tweeters, Tectonic TEBM46C20N-4B BMR 3"
Full-Range (4), and TB W6-1139SIF subwoofers (2). Crossover: 1300Hz and 175Hz, approx 4th order acoustical. Plate Amp: Dayton SPA250 (2).
And, finally, a few miscellaneous pics from the door prize, swap, and back room tables. I brought the Wollensak R2R tape recorder for demo. Craig scored the Heathkit audio generator. I picked up the soldering smoke filter and a used copy of Floyd Tool's Sound Reproduction.
Meridith's speaker still kinda creeps me out...I was expecting it take off and fly around the room at any time... spooky looking thing. 😈
Did sound neat, though.

Does the man standing next to them have a name?

DSP worked it's magic. IMO they sounded like full on towers with all the fixins!

Usher 2 ways designed by Dennis Murphy and modified slightly by Robert Clark. Drivers: 8945A and 9980.
Pretty sure that is the 9950 tweeter. The 9980 was an OEM metal dome.

The top one is Craig's and the lower one belongs to Brad.
Pretty sure the 2-way ribbon was Craig's. I've seen those speakON adaptors at Iowa in the past.
