Doctor's Orders-Part Two-The New Listening Room Of Steve Williams

[microstrip]

I bet if yiu do a search here of posts by reputable members who own Wilson and they say the reason so many people come away from Wilson rooms at audio shows and say they didn’t like the room . The posters then remark that this is because the upper modules were set up for a taller listener. Or how many times have I read here that the speaker is like a finely tuned laser beam. This forces the issue that there is only one good person who best fits the sweet spot in a well set up Wilson speaker. That should obviously be the owner, which is a good thing. But as thedudeabides says it forces away other listeners if they have to continue to change positions to sit in that sweet spot with the hope that they are themselves in focus

Steve,

I was not addressing specifically Wilson speakers or just WBF posters. It was why I suggested debating it in another thread. There are good reasons, easily explained, why in your particular room your old X2 had a narrow and critical sweet spot. Again, if there is interest of WBF members we can have a separate thread on sweet spot characteristics.

at this point Francisco, it's honestly the furthest thing from my mind but I believe you missed the point of my post and are asking a different question If youre interested go ahead and start the thread. I wont be participating

Nor was I.

Agreed. Sweet spot characteristics would be an interesting discussion.

Good idea to start your own thread

My ship has sailed on this one.

I’m glad that there’s interest in the rear construction of the Ultra line speakers, as I believe it’s quite unique in the industry. Folsom is right on the money in describing it as an “aperiodic” design as opposed to a sealed cabinet as this “acoustic resistor” in principle serves to evacuate air from the enclosure, which vastly improves frequency response and impedance peaks. With ZELLATON proprietary drivers, this results in superior bass response while allowing the speaker to take on an electrostatic quality enhancing an atmospheric and completely boxless design many have attested to in these pages.
Where this “aperiodic” design is nuanced is that most of these designs use a port whereas ZELLATON uses a vertical and large open baffle spanning the rear of the speaker, achieving greater air evacuation over a port, hence my description per Steve as a quasi type.
In terms of sound behind the speaker, it’s interesting because as opposed to a conventional port, one does not feel pressurized air being forced out. Rather, ZELLATON speakers just breath in the rear, allowing for closer placement to the back wall (as opposed to a port which needs adequate distance to perform in a more linear fashion).

Yes, this principle was used by Dynaudio in their speakers and kits in the 90's - I still have a few damped vents that I never used. Current speakers, using modern technology materials with much better porous acoustic properties materials for the "acoustic resistor" should have much better performance.
