        Yes John, I believe that you are right, it is very apparent in the video that the cells of the 3C’s are angled at about 22.5 degrees to give the 45-degree curve.

          I’m not sure what the dispersion angle is of the 3-6 cell models. I’m waiting to hear back from Roger about that.

          Take a close look at the first video in the other thread. As Roger is explaining how the membrane is attached, he appears to be using a 3C model, most likely a 745. Note that the center cell appears face on while the two adjacent cells look like they are angled at about 22.5 degrees to give the 45-degree curve.

          I guess the 4-6 cell variants would have cell angles that vary to maintain the 45-degree total.

            For the narrower models, do they effectively take the 45 degree dispersion model and cut cells off of it (if they cut half the cells off of it, would it be a 22.5 degree model)?

              Ah, got the impression that it was a new order.

              Actually, I knew someone had ordered a custom version some time ago, just couldn’t remember who.

                  There were a few folks that ordered the “skinny” versions. I was definitely not the first.

                  Achipo,

                  Congrats on the “Slim” 745!
                  Is it a 3C?

                  Now the hard part begins ………..waiting!

                      The waiting is long over–I received them in December, 2022.

                      John V,
                      Thanks for the picture. Expanding it and reading the fine print was more informative than the video.

                          Sounds like Roger is productizing the “skinny” versions. I ordered a custom 745 “skinny” and couldn’t be happier.

                          Well, maybe if I’d ordered the skinny 845 which would just barely fit…

                          Thanks for the updates. I already knew Dr. West was offering sizes other than what is listed on the website which he plans on updating. Now it is official. The video introduction made it seem like there was new technology.

                          I think the move to more slender speakers is a great idea. I can see how it would generate more interest.

                            To expand on ernestov’s comments, I received the following email from Dr. West when I asked “What’s new at SoundLab?”:

                            “Concerning new things going on in our company, we discovered that some people would like a more narrow version of our speakers.
                            I am working on our website and a dealer news letter to announce this. As you know, our panels use a single membrane. The supporting
                            frame creates flat sectors about 5 inches wide which are the length of the speaker. Each sector is angled with respect to adjacent sectors by
                            about 15 degrees to provide controlled horizontal dispersion. We have given these sectors a name: cells. As you know we
                            basically have three models and each of these models is available in 5 different sizes. Take as an example our Majestic 745. The
                            7 suggests the approximate height and the 45 gives the horizontal dispersion. The number of cells is a standard 7. However, the same
                            speaker is also available from 3 to 6 cells, so if someone wants a more narrow Majestic 745, for instance having 5 cells instead of the standard 7, the
                            model name would be Majestic 745-5C. I am not putting the number of cells on our standard models, only the narrow versions which are options.
                            Having this option provides a speaker that has less effect on room decor and helps to pass WAF (Wife Acceptance Factor). As you would
                            expect the approach reduces bass dynamics some, but surprisingly not as much as I had expected. Anyway, this is the latest innovation and
                            is something that you can mention to others as it is now available.”

                            In a subsequent email, Roger wrote:

                            ” I am not offering them as
                            independent models. Rather, I am offering them as variations of our standard
                            models, which is in fact the case. We are demonstrating them in the South-West
                            Audio Fest in March to see how much interest develops. I have attached a
                            copy of a photo, see below, that we are using, which shows our most narrow model, which is about 20 inches wide.

                              Well, considering the speaker is new and has not even been shown yet….at least he alerted some of us what is coming (and appreciate it, through his video), but gas bag?

                                I just spoke to Soundlab. I got all the info. No need for you guys to call them. The new design was a compromise meant to mitigate the wife-acceptance factor. It uses the exact same technology as the existing 745 but with less than half the surface area but it sacrifices efficiency. The new 745-3C is beautiful, slimmer and sexy but not at the same level as the existing 745.

                                  What a total gas bag. In 9 minutes I learned nothing about the new speaker. I wanted to know if there were design changes from my 545PX. Total waste of my time watching this video.

                                  I got to the video through an email so I missed the tip to go to the 4-minute mark. Even so, there was no real information.
