 So now that I've more or less settled on getting an Optoma HD70 projector, I need to put some thought into my screen.
There are a few concessions I'm forced to make. First, since my HT is also my bedroom, I want to retain the ability to use my little 27". The solution I have for this is to simply hang the screen off the ceiling in front of the TV and my center channel speakers. Then, when not in use, it'll just lean up against a wall.
There are, as I'm sure you're aware, certain pros and cons to this. On the plus side, the screen will sit in plane with my front speaker array and I'll retain the functionality I want. But on the other hand, the screen will need to be accoustically transparent because the centers weill both be behind it. This in itself has some pretty nice advantages, but it complicates my screen building endevour.
I have yet to fully research the topic, but I'm posting this now, and checking for replys after I poke around the forum for some info.
I know there are commercially available screen materials that are acoustically transparent, but I've also noticed the price is a few magnitudes higher than I'd prefer paying.
My desired size is going to be a 74" diagonal, 36X64", with a throw of between 9 and 11 feet. My ambient light is well under control. So brightness shoulndt be a huge problem, right?
Thanks, I going to start reading now!  |
To get you started...there are a couple of tried-and-true acoustically transparent materials. One is Phifer Sheerweave 4500, another is SMX (which may actually be Sheerweave...I can't recall), and another is Center Stage -
link, cost ~$140 (and there may be others...I'm sure folks will chime in). Keep in mind that there are voids in AT screens (could be holes, could be a weave), and you don't want the direction of the pattern to line up with the pixel structure from the pj. So, you should plan on ordering enough fabric to create the screen at an angle to the fabric pattern...anything over 15 degrees or so should be fine (you may not even need that much).
In the "stick my nose where it wasn't invited category": Would you consider mounting your screen high enough such that the center is just below the bottom of the screen? It would definitely open up your options regarding screen options. On a screen that size, you could slap together a laminate screen that would you give you a great picture for relatively little cost.
As far as brightness...not going to be an issue at the size you're after...even with AT material.
