JBL Synthesis - Room Design and Treatment

[Titanium Dome]

I think they look cool. Can they be painted without affecting their performance?

Yes. In fact, I put some expanding foam insulation in the groove on the back side to dampen them a bit more, which would affect them more than a coat or two of paint.

They also come in black.

You've seen the foam?

[Mike Ronesia]

I have, that's some great stuff!

[UreiCollector]

Looking great! Enjoy!!!

Ti Dome,
I don't know I'd want to put them in a LR though, alright in a dedicated HT.

Have you listened to just a stereo source in that room? If so hows the soundstage with the LCRs right against the front wall?
Have you used the S4Ai in the monopole mode, while listening to MCM?

You don't want boobs on your LR wall?

Well, I've got plenty of fold outs to hang on the walls for those.

Even before I was aware of the importance of polycylindrical diffusers, I was drawn to them. Here I am in Las Vegas a decade ago trying to find the sweet spot between these diffusers on the wall in Mandalay Bay.

A little to the right ... just a little more ... no - not too much ... OH, there it is.

[Mike Ronesia]

Those look like they would go better in the front then the back.

[Fred Sanford]

The might make nice headrests on the theater seats...but it could be tougher to hear the rear speakers.

Before I move on to the other thread (JBL Synthesis--something BIG is coming) to describe the calibration, I'll post a few more of Grumpy's images of the set up.

Great pictures, and guys, what an effort! Doug, it looks fantastic.

It’s quite a bust!

The screen is up! It's attached at the bottom, but we've done a temporary bit at the top. Now that it's in place, I can build a small frame to attach it to the ceiling.

The Stewart Filmscreen Luxus Screenwall is 110" on the diagonal (54x96) and has the Microperf feature to allow the center to be behind the screen. The wrinkles at the bottom will fall out; in fact, they're almost gone now.

I had a couple of follow up questions about the screen, so I'll try to get it all correct:

Stewart Filmscreen Luxus Deluxe Screenwall—StudioTek 130 Microperf 110" diagonal screen.

There, now anyone can Google it and find out more.

So is the Dome, enjoying the decadent delights of his JBL Synthesis because you’ve been very quiet for the past week?

I've been working on something else, but will get back to it presently.
