Pro's and Con's.... AT or not...

post #1 of 3
Thread Starter 
I'm sure I'm missing something, cause I usually do... Is there a good reference (was hoping for a sticky post.. : ) ) on the pro's and con's of using an Acoustically Transparent screen vs a traditional screen?

Like, how does it affect image, are there special concerns from a mounting perspective on the projector like distance ratio to projected image size to prevent moire, etc.. does the choice of AT dictate different projector selection? what about gain, should i be considering something different if going AT?

I thought screen selection would be simple, but alas, it is as complicated as all the other aspects of the theater, and i suppose it should be, it is what you are watching so to speak...

Thanks,

It's entirely about the audio. Well, one way it could incidentally help out with video is by increasing the available space for a larger screen, depending on room dims/setup. Otherwise, entirely about the audio. Off the top of my head, in no specific order: 1. Audio/dialogue truly locked on to the screen. 2. Using identical speakers allows the best possible match. 3. All identical drivers being on the same plane allows for best possible panning effects. 4. (Typically) larger choice of (all important) center speaker usually allows for greater power handling. 5. (Typically) moving the speaker away from being to close to a boundary (ceiling or floor) reduces SBIR, and helps clarify audio. 5 (Typical) avoidance of horiz MTM center speaker configuration gives clearer dialogue intelligibility at the extremes of seating. I haven't talked about this stuff in close to a couple of years, so I'm probably forgetting something.

Moire can be avoided with my own Seymour XD screen by "tilting" the screen, which is pre done for you if you're not going the DIY route. This is only really an issue with LCD tech, as the fill ratio is much lower than the competing techs. But again, just tilt, you're still good anyway.

AT only dictates choice of PJ selection in that you may need to tend/compromise towards a brighter PJ. (I don't, but I have a semi-cave, and get by fine with 126" with a modest JVC; no 3D here however, which makes brightness a much bigger issue all of a sudden, and don't ask me about it, because I don't care.) And that's only if we are talking about weaves. Microperf screen, you can perf many kinds of screens, so you can get one with considerable gain, for instance. You will probably be paying considerably more for one of the latter, at least of the few brands I'm familiar with. Others will be more knowledgeable about selection. It does require (considerably) greater space between speakers and screen, however. I just about to forgot to address your other query: I've never read anything changing with "distance ratio". The only thing again, is if extra brightness was desired; closer setup makes for brighter (further for more contrast). Mine is far. wink.gif
