  • I think that's the first time I've ever seen or heard Eaton drivers. What size were those Marty? 12's?

  • A few people asked about the demos and details from the event. I'm still enjoying the last day of my vacation but later this week I'll upload them to share, PM me on this forum is you want to details to download them.

    Glad everyone had a good time! It was good to see everyone again after so long, and so many amazing speakers - holy cow!

    In regards to the first Eton, maybe Wolf can recall the details but I think I remember at InDIYana years back hearing a speaker someone shipped to the event. It had the SEAS DXT tweeter and smaller Eton symphony woofer. Unless I'm mis-remembering

    I see Scooter use the same mid and tweet that Bill did in the Totally Flat design. How did those sound?
    I hear the lx521 design was not impressive, I'm also curious about the A26 design with the cat 378 how did those sound?
    I guess I need to get out that way again and maybe meet this Brad person everybody talks about. His stuff just looks phenomenal.

    I thought these really sounded good, nice and "airy" on top with a smooth, wide open midrange quality. But I am biased, seeing that I used the same tweeter/mid combo. What model woofer was used on these?

    The woofer is the SB Acoustics SB15SCFR39-8. Both Madisound and Meniscus carry it. Parameters work pretty well either sealed or vented. I ran them sealed in about 0.5 cu. ft (14 liters). Mine were a door prize courtesy of Meniscus a few years ago.

    I couldn't find them looking for that part number. I found them on the Meniscus site without the "-8" in the part number. Do you know what your F3 was?

  • Memory only partially failed, it was an Eton hex hexacone woofer and it was 2014:

  • Nick had a build he brought to DDIY a number of years using that same Eton woofer. Had a German tweeter, as well. Mister Schmidts he named them.

    I have a signature.
  • I know Bogdan had a huge 3way at MWAF once with an 11" Eton woofer, around 2006.
    Those 2ways above were Todd England's in 2014, sounded great!
    PaulK used the older 22mm tweeter and 2" midrange in his TriLangle II design around 2006.
    Of course Marty used an Orchestra series woofer, and I think I've seen another one used somewhere recently.

  • It was likely Nick's.

    It was right around 60 Hz.

    Keep an open mind, but don't let your brain fall out.

    Bwahahaha!! ^

  • Didn't Seth Horton do a 4 inch Eaton 2-way?

     John H, btw forum has decided I don't get emails

    Oh, the A26/CAT378 was Maynard's design!? I have no doubt it was listenable then. Maybe Maynard ought to come up for InDIYana 2023 and reshow those beauties...

    Ben, I'll bring them over. Post a link to your planning thread.

  • I built 3 way actives many years ago that are all Eton drivers. Still using them and still love them.

  • I remember seeing the images of those AGES ago, as they looked very good.
    Now I know who built them!

  • Big thanks to the organizers. I had a great time.
    Also liked Scott Sehlin's quip about my "snake oil infused" speaker finish. LOL

    I have started working on the videos... about 9 hrs worth...! I was stopping and starting recording, so that I don't end up with a giant video file that my laptop would barf at...

    Anybody has any notes regarding speaker names / designer / drivers? Would be really great to add some details to video description. There would be a bunch of smaller videos since youtube won't let me upload anything over 15mins (new / low subscriber account). And smaller videos are anyways easier to manage and consume.

    I'll start uploading in a couple of days as I sort these out.

    thanks Tom for your expertise, tips and help. I'll be ready for streaming next time, hopefully - Still a few challenges and hurdles to cross!

    Thanks, Ani. Can't wait to see the videos. If you hurry, you can beat Tom before he has a chance to post the videos that he shot at last year's IowaDIY! :) (just kidding, Tom). I have pictures of all the tent cards, so if you need speaker "names / designer / drivers" just let me know and I can send you the data. In the next few hours, I'll be posting pictures of the speakers that have not been posted yet by JR, Ron, or Tom. I'll include some tent card info as I go along. Bill

    I love seeing videos of guys presenting their speaker projects... until I see myself :#
    I guess that's why I chose to be the guy behind the sound board instead of the guy up on stage ;)

  • Thanks Tom and Ani for all your hard work.

    I just went through all my pics and noticed that the only speaker missed by JR, Ron, and Tom was Wolf's Nephlia's. So I'll post a new pic of that one. I have several "humorous" type shots of guys presenting their speaker projects, so I will post a few of those. Plus I have a shot of Bryan photo-bombing the photographer that you will have to see to believe.

    Here is Robert Clark's presentation of Wolf's Nephlia speakers. He purchased them from Wolf a while back and was selling them at a very reasonable price. I would have bought them because I really liked the sound (excellent soundstaging and airy, upper octave detail), but I did not have room for them in my car. These were the 1st place winners in the Speaker Design Competition >$200 category a few years back.

    I wasn't quite sure what to do with last year's videos. I only have the presenters and you can't even see the speakers in some of them. I scaled all the clips down from 4K to 1080 and gave them to Ani. I think he's going to put together a montage - hopefully with some stills of the speakers.

    Here are a couple pics of George presenting his high end MTMWW 3 way towers. He did not fill out a tent card, but I believe, from other discussions I had with him, that the tweeters were the Radian LT6 planar ribbons in a red waveguide. The two mids were Faital 6RS-140's, and the front facing woofers in two lower cabs were 9.5" SB Acoustics. One of the two lower bass cabs contained two side firing passive radiators, while the other lower bass cabinet was completely sealed. The small device in the last picture was a small wooden terminal that George used to apply pressure evenly across the speaker wires in an attempt to reduce the series resistance.

    EDIT 10/30/22: Correction to drivers used. Per George, the tweeters were the newest version of the Radian LT3 mounted in a Radian Waveguide and painted red. The D'Appolito mid's were 5" Faital Pro 5PR160. And the woofers were 9.5" Satori WO25P in parallel.

  • I know it might be a bit of work, but as I'm from Oz, and read this Forum regularly, I'd really like to put faces to names. There's a photo earlier in this thread which shows the participants, would someone be willing to a make a list of the people, please? Not just for me, that would be selfish, but others around the US might be interested, too.

    Thank you

    Geoff

    Sure, I can do that. I will edit the text in my posts above to include first name and last initial of each person shown in the frame. Bill

  • I want to say thanks to everyone, who's hard work made this event a success. It was good to see some folks that I hadn't seen for a bit. It was fun just hanging out the evening before the meet and it was good to see Jim Holt & Dave Ellis on Saturday.

    I really enjoyed this year's offerings. Of those designs, I liked how the Linkwitz OB system handled the listening space (nice sound stage). There were several small speaker designs that also punched well above their weight on the demo tracks (the Ice Cubes & SB Micros come to mind). George's "work in progress" three-ways & Ani's active, dsp based four channel amp running his two-way offering also were promising. At the end of the meet, the Peerless "beast mode" tweeter's high SPL playback capability running in the 3.5-way OB and being really pushed hard by the Sampson amp on the "Barbie Girl" track was impressive. Most non-pro class drivers couldn't handle that program level running in that way. I was surprised that the $24 DX25's didn't really complain.

    I spent a bit more time listening at the rear of the space this year and took some mini breaks out of the room to spare my ears. I'm glad that I did. All in all, a good time was had by all. Also a shout out to all the female attendees.
