Accurate timbre means that I can easily tell a plucked acoustic upright bass apart from an electric bass, or the musical qualities of a tuba apart from a keyboard bass. When set up properly, there is no excess bass overhang, just great mid-bass punch and deep bass extension all from a single relatively compact subwoofer package.
I was happy to help install Craig's new screen on Saturday. It is very solidly mounted with Unistrut directly to the ceiling joists and 4 threaded rods down through the ceiling tiles suspending the screen, The whole system will probably hold 1,000 lbs, so its not coming down anytime soon! LOL The final mounting design also resulted in a much "cleaner" look too. I ended up machining a few custom spacers from 1/4" thick aluminum bar stock to allow a solid and flat surface to tighten the Unistrut and screen rails together, and they worked great.
I stuck around a while after Ryan left and helped Craig move all the Triad speakers back into place, and we measured everything to dial in the imaging perfectly. Acoustically, the speakers sounded as fantastic as I remembered them, and Craig hasn't even felt the need to re-run Audyssey yet.
I will also say that this new Seymour AV screen with the new 4K fabric and separate 16:9 masking is a very definite upgrade from his previous screen. Even though it is slightly smaller, I think it is sized better for the viewing distance. In combination with his new JVC projector, the image is bright and fantastic - getting very close in performance to a good OLED flat screen display in every way, except the black levels. I am anxious to see how good it can get once Ryan has a chance to calibrate the projector to the new screen. The image when projecting 4k HDR material was amazingly good already!
Thanks for adding your comments Dennis. And for all your help with engineering the mounting system and the installation. It turned out better than I could imagine, and MUCH better than if I had done it myself.
I agree that the new, smaller screen size is better. Part of the improvement is the screen material, which is brighter than the old CenterStage, (non-XD) material. But I think part of the improvement is the smaller screen. I had calculated viewing angles prior to ordering the screen using the following formulae:
I sit 9.5' or 113" from the screen. Using the formula for a 40 degree, 16:9 Viewing Angle, (VA), = Viewing Distance, (VD), in inches x 0.84, results in a VA of 40 degrees with a 95" 16:9 screen. The diagonal size of my 16:9 image is 93".
Using the formula for 2.35:1, (VD x 0.95) yields a 107" screen for a 40 degree VA. My 2.35:1 screen is 115" diagonal so I'm closer to a 45 degree viewing angle for my favorite AR. It's completely immersive without being uncomfortable. I think it's actually a better size in my room, at my viewing distance than my old screen, which could cause some head turning and motion symptoms, (especially for my wife).
I wanted to get the room cleaned up before I reran Audyssey. I'm now ready to run it, and I'll get to it either tomorrow or the weekend.
Thanks again for all your help! I hope I can return the favor sometime soon when you start your theater!
