    Re: AXPONA 2013 in Chicago - who's going?

    Nice catch! I missed the tractrix part on the Volti Alura discription. And on second glance the Procella's WG has a different flange. Also, their propaganda describes it as "constant directivity," so it's probably a different (possibly bespoke) part.

    And man, wouldn't it have been nice if Woot had more than one each of the Pio EX in-walls in their sale today?

      Do you have any pictures of the peachtree prototype thingy?

        I did ask them but they would not let me take any pictures.

            Hey Craig,

            What a fun show. Compared to RMAF in Denver last October, there were at least twice as many people in and out of the room. While there may not have been as many exhibitors, the ratio of attendees to exhibitors had to be much higher. The flow seemed non stop and the days just flew by.

            It was great seeing some of the guys from the forum stop by. Got to have dinner and beers with Bryan on Friday and Saturday. Would have been nice if even more of you could have been there. And shaking the hallway with some raucous music Friday night was pretty fun too, until the party pooper knocked on the door . . . :D.

            Those monoblocks feature an 805 tube and produce a clean 40W. Pre-stage uses the PSVane CV181 feeding an EL34 as the driver tube. It really was all we needed to fill the room and then some.

            Here's another pic showing a close up of the setup.

                  I also wondered about unlined, thin walled enclosures........

                  Coincidentally, I picked up an AudioExpress copy in the lobby and it included a blurb about a Coleridge Design Associates aCube speaker which uses Cast acrylic enclosures which claim good damping properties without lining. I could not verify from the website that the Waterfall design uses cast acrylic, but perhaps it does. Here is a quote from the aCube website:
                  ......acrylic has very high internal damping, therefore the enclosures do not resonate and radiate sound as much as other materials e.g. most plastics, wood and aluminum. This means the acrylic speaker enclosures can be made light and free of internal bracing and damping materials ensuring the sound is crystal clear.....

                  Perhaps that is why they get by without bracing or lining.

                    That may limit sound transmission through the walls to some degree, but it is almost a guarantee that if you took an impedance sweep, you'd see all kinds of little glitches where the internal standing waves are sitting. It looks cool, that's for sure, but cast acrylic doesn't stop the laws of physics from taking over in the enclosed air space.

                        Lol! It cracks me up that at the prices of some of these they had such poor cable managment. That one with the cable stands had a huge mess behind the components. When 3/4 of the price is in the finish and details on most of these why skimp on cable management?

                          Because as long as you have $800 cable risers lifting the "proper" cables up off off the carpet, the other $20k-worth of cables can be slopped all over the floor in a big ball. :p

                            I quess the risers also negate the orange extension cord. :D

                              reminds me of kids throwing doo-das like air intake and fart exhausts on old beat up 4-bangers and by the time they are done, based on description of each "improvement" they got 734HP. Yet the car just becomes loud and uncomfortable but not much faster.
                              Good thing tho is that these water hoses are hooked up to actually good speakers.
