You are right, the bass Radialstrahler emits mostly in a cylinder launch wave, but also as a spherical point source wave, and the floor and ceiling reflections matter, as they do with traditional speakers. Some of the energy gets to the floor and ceiling. The midrange and tweeter are approximately spherical Radialstrahlers.
I went back to look in my archives and found the source of the panels for you. Ecophon wall panels made by Saint-Gobain, a French company. They are widely used to treat reflective rooms in domestic and professional settings. Probably not available in the US but local alternatives most likely exist.
The floating is achieved with suspension hooks from the ceiling, see picture below.
I have been really happy just using (4) Stillpoint Aperture diffusion panels on the front wall, and (2) on the rear wall.They are very powerful devices and can be used sparingly.
Unlike conventional speakers, the MBL’s really don’t need any side wall correction and like to reflect.
My ceiling height is 11ft.
When Jurgen Reis demonstrates the MBLs at our audio show in Brussels, he uses plants for diffusion/diffraction behind and on the sides. Palm tree plants everywhere !
Try some diffusion on the sides, as recommended by Jurgen and MBL. It doesn’t cost much and you might like it.
It’s funny you mention that because Jeremy from MBL USA does the same thing at the shows like Axpona! When I saw your pictures with the plants, I thought it looks just like the Axpona set up! I will add the pics.
Just received the Qstab Pro/black cd clamp for the Jay’s CDT3-3. Sounding pretty great so far. Many more hours of listening to determine if this laser sintered tweak is worth the dough. Initial impressions say yes of course!
Very small part of my system but thought I’d share initial impressions with the Little “Fwend” tonearm lifter on my Rega Naia.
Those clever Norwegians have built a very nice gadget and now offer a mount specific to Rega P8/P10/Naia that utilizes a hole in the plinth right where you want to mount the lifter. Beautifully machined, assembled and very gentle lift with a tiny amount of force triggering the piano wire to initiate. So far appears to offer very consistent trigger position too.
One caveat: You must remove the lifter to replace the dust cover. Not a big deal as the gizmo attaches to the mount with a magnet. I’ve added alignment “dots” to make install very quick and easy.
Certainly not cheap but feels like it will do the job I hope for a very long time.
That’s really funny because @Dirk hates hates hates that counterweight. Beauty is clearly in the eye of the beholder. Frank Smilley at Groovetracer is a master machinist and his stuff is magnificent.
Apparently the lower center of mass helps with tracking although I don’t fully understand the logic.
Yes, that little device is expensive. However, better to think of it as cheap insurance to save an expensive cart from having to be unexpectedly replaced.
After one late night of record listening and one too many craft brews, I dozed off for probably an hour or so. During the time I was sleeping, my cart was playing bumper cars in the dead wax label area spinning around and around. I thought nothing of it when I woke up, properly shut everything down and went to bed. On my next listening session, I discovered the very tip of the needle was missing. Having that little device would have saved a lot of unnecessary aggravation.
