I will have both light controlled room for movies and some ambient light for parties/sports.
Thanks - Jim
The reasons for Silver over White are:
Better Ambient Light performance
The reasons for White over Silver are:
Lower Lumen PJ
No need for REALLY SIGNIFICANT
Ambient Light issues are very minor or non-existant.
Desire for brightest image (White reproduction) possible.
White is a choice for dedicated Theaters whose PJs are over-achievers as far as Contrast specifications are concerned.
I suggested Silver as the backing for the latter because it can give a bit of a contrast boost without unduly absorbing (attenuating) the light that passes through the top layer of spandex. In reality, the second layer acts to both re-utilize absorbed light by keeping it close to the projected surface.
If the top-most surface is darker than the rear surface, then the presence of the captured light off a White surface behind the top surface acts to boost White levels and restore any color dynamics and gain lost. A Cloth-like version of the "Light Fusion" principle
. I actually pointed that out all the way back in 2008 when Spandex first became a viable option. But even so, painting always made enough difference that until Acoustic Transparent screens became more desirable due to more & more dedicated theaters being built by those with DIY budgets, few wanted to deal with the loss of image brightness that AT screens delivered when the PJ involved had lessor lumens.
That has changed significantly, and the 6010 is one of the best examples of a High Contrast / High Lumen PJ there is to point to.
Black (...or Silver...) under White would of course be one route to take with the 6010 as it's lumen output is quite a bit higher than even the 5010**
. If one has a dedicated Theater, a 6010....calibrates the PJ to it's best Black Rendition possible, (...runs it in "Cinema Mode"...and Economy ) then in no manner or way would they be apt to suffer from anything less than a terrifically dynamic image...at almost any size. Such can hardly be said about ANY mfg AT screen in existence except the higher gain version of Ruben's AT offerings, but beyond the cost of such lies the fact that the AT properties are not any better...if as good as Spandex.
...it's higher Contrast allows the light output to be focused on the brighter areas of any image...)
So back to Silver over White. Silver does wonderful things to enhance the depth and dynamics of all colors. But dependent upon the depth of Gray that comprises the overall shade / hue of the fabric, it can attenuate the incoming light...and if any of that light also passes through the surface...even more reflectivity is lost. White under layment captures and keeps that absorbed light in the local neighborhood where it helps keep things looking brighter than it would otherwise.
Having a PJ that pumps out considerable (...or adequate...) Lumens but needs help in the contrast department is the greatest reason behind the use of Silver over White.
That said...obviously a PJ with great contrast on Low lamp and Cinema Mode in a dedicated environment can do it's absolute best with White over Silver.....or Black.
Lastly....any choice that is used as the second layer will still offer equal ability to mask the presence of any "Rear mounted" speaker array. But the darker that 2nd layer is....the better it will do the aforementioned chore.
