Since my last post, I have actually made good strides. The delay in the new JVC's shipping helping enormously!
First up, with the shift to native 4k I decided to look at screen material again, and ordered large samples of the v6 material and SSE Neo that I compared with my Falcon, Seymour XD and UF and Svertson SAT-4K. I ultimately decided upon the v6 as it gave great contrast, excellent pixel deliniation and integrated the black backing. The sample, and ultimately the final screen, appeared much nicer than the small sample I'd previously evaluated with
a couple of years ago (thread in the DIY Screen subforum). He was over this week and made the same comment. From my post
on 11/12/18 in the v6 thread:
My v6 screen arrived almost two weeks ago, and I finally got it built and hung this weekend. I purchased the material via Mike Garrett, and decided against retrofitting to my Carada frame given the current phenomenal pricing of the AVS frame. My Carada was 118" wide 2.37:1 and the AVS is 120" wide 2.37:1. I may have bought the Dream Screen frame for future motorized masking, but the only options were 112" and then 138", which wouldn't fit my room and I didn't want to go smaller than I was used to.
The frame arrived wrapped in plastic in one tube, with the material rolled around a dowel in another smaller tube:
The included tool for tucking the material into the grip rails. They forgot the Digornio
The completed screen:
My previous screen (Falcon Vision) would light up the back of the screen and the black Knauf insulation behind. I couldn't find the photo I'd previously taken of that, but a direct shot of how the projector lights it up is very representative and shows how reflective that black material is:
There was no point including the photo I took from behind the v6, as there was no leakage at all! The apparent contrast and sharpness are both significantly increased, somewhat from the lack of leakage reflecting back through the screen presumably. Obligatory screen shot (from Rogue One) taken with my aging Samsung Galaxy S7 phone (which actually demos the lack of light leakage. With the Falcon the proscenium is more lit up with no framing above the screen currently. With the v6 there is just a little from the scatter from the screen)
I took some REW 20-20k sweep measurements with the Carada and then v6 screens up (CSL calibrated umik at the seating position), though haven't analyzed them yet. Given the location of the drivers, below 300Hz will need to be discarded from the comparisons. I'll plan to get those up soon.
So far though, I'm extremely impressed. The final result is so much better than even the 2'x2' sample suggests.
