    SP16 "Critical Mass" by Torbjorn H.
    SP18 "Neo 8 Cherry Tower" by Steven G.
    SP26 "Totally Flat MK II" by Bill S.
    SP?? "??" by Tony H. (>$200, no tent card)

    I did not take a full length picture of SP16 "Critical Mass". John, did you take a picture of this one that you could add? Also, Tony H's speakers did not have a tent card. Does anyone remember the name of his speakers. They were the last speaker to play in the >$200 category. Thanks.

      That should do it. Let me know if I made any mistakes or missed an entry.

        Correction: I noted in post #36 above that the new venue overall dimensions were approximately 50 feet wide by 80 feet deep with an 11.5' high ceiling. I checked my notes and I was quite a bit off. The overall size was 70 feet wide by 100 feet deep. The suspended ceiling was correct: 11.5 feet. This was actually quite a bit bigger than the dance hall used last year.

          I liked the new venue as well. Very benign acoustically, no matter the project that was played.

            Congrats to the winners! There were so many great sounding projects again this year. Seems to continually get better.

            I can't say enough on how great it is that PE puts on this show for us and how awesome and friendly group of people they are. Thanks to you all at PE... It really is the highlight of my summer, especially since it is near my birthday and I have an excuse to give(guilt) my family in allowing me to always attend ;)


            Bill, Thanks for taking the time to get all these shots and posting the results and photos.... I imagine it takes quite a bit of time to track and organize this.

              Thanks, Troy. I really liked your tiny DUT-V2 speakers. I think they were the smallest speaker at the show (they looked a little smaller than Shawn's Woodies, to my eyes). Neat little sloped crossover cover on top. I remember there was a loud pop during playback and then Jason quickly turned the volume down a couple dB. It still sounded good at the lower volume level, so I think the tweeter survived. Or was there damage to the tweeter?

                Thanks for the compliments... I think all parts seem to have survived the pop. I ran some impedance sweeps on Sunday and they are identical to before the show and they also sound on par. I will measure to be sure, but think all is well.

                So far I am baffled by what it was or its cause. Some were asking if the midrange might have bottomed out, but I've run them through the paces using that same track and they distort badly before any pops like Saturday. I'll probably keep working on it to find out for certain, or at least give some comfort/hope it was just an anomaly.

I wish I could have heard them, but I left early for lunch and missed the Dayton session completely. (I needed more time to rummage through all the old tube junk at the swap meet.) I bet they sounded very good. I took several close up photos of your coaxial tweeter mount; looks very professional.

                  Thanks Bill. I thought both your entries sounded very nice and was glad to finally get to hear them. I’d love to see all your pics.

                    I really liked those little speakers. I also enjoyed talking to you at the show. They just look really cool, your crossover layout was very clean, and the crossover covers were very innovative and well executed.

                    I think the pop was an artifact of the music source and small speakers (inherently low efficiency requiring additional input power to meet the spl requirement), not a fault of your design. I’m not sure if it was between all tracks, but I noticed woofers on everybody’s speakers driven to a quick but large excursion spike between the “pink” noise and first track.

                    I remember hearing yours pop but don’t remember when. I suspect it was right after the noise track. I would put no effort in finding fault in your speakers because I don’t think they are the cause.

                      Check for a cold solder joint. I had a similar occurrence at a NY/NJ DIY.

                            That's interesting. Another criterion was added this year for the judging, Dynamic Range, and that change was not shown on the MWAF site. Maybe my score sheets will arrive today, too.
                            Paul
                            Well, DUH on me. I went back a few years on my Judges' score sheets and see that Dynamic Range was added in 2017.

                              You appear correct. Scores are probably much higher and tightly grouped compared to last year, especially in the $<200 category. Last year I took 1st place in the $<200 with an average score of only 7.88. Paul K. took 2nd with an average score of 7.17. If you recall, there were only 9 entries (several no shows or cancellations in the <200 category). Tom Z. would probably have took scored higher and took 1st place last year with his Summer Winds speakers, but he accidently wired one of his midrange drivers in reverse phase. Here is a link to last year's score chart thread:
