[18:08] Tim: Hi guys, looking for an acoustically transparent 130" screen.
[18:09] Johnny: has joined the conversation
[18:09] Johnny: sure does this need to be motorized?
[18:09] Johnny: or fixed frame screen?
[18:09] Tim: nope.. fixed wall.. I think I like the Aeon series..
[18:10] Johnny: For the Aeon we have a 135" diagonal
[18:10] Johnny: which is model AR135H2-AUHD
[18:12] Tim: this is my first screen. What will that do if the screen is larger? Does that throw off the overall size of the picture?
[18:12] Tim: Also, is the audio transparent really that necessary for the center channel to be behind it? What would the loss be?
[18:13] Johnny: There is minimal attenuation. Your ears will not detect the difference. It also does not affect picture quality.
[18:15] Johnny: If the speaker is going to be behind the material, the acoustic material is needed because a regular projection material will muffle your sound.
[18:15] Tim: The projector is the Epson 504UB.. it's sitting roughly 13'=14' away.. ceiling
[18:17] Johnny: for a 135" the screen calculator https://elitescreens.com/front/front/cms/slug/screen-calculator recommends a throw distance of 18'.
[18:19] Tim: ooofff.. that may be too far back. Or would it be better to shrink the screen?
[18:19] Johnny: I recommend either selecting a smaller screen or contacting Epson to see how adjustable the throw sizes are. You may be able to adjust your projector lens and keep the larger size.
[18:21] Tim: ok, the logistically I have a hallway after 15' back.. that's why I was asking about the 26'.. 18' would be directly in the center of the hall..
[18:21] Johnny: I see
[18:21] Tim: what's the next smaller screen?
[18:21] Johnny: for a 120" it recommends 16'
[18:24] Tim: alright, so 18' is the sweet spot then. That will be a 130" screen. I do not see that model number when I search on the screen size page.
[18:25] Tim: err,, 135" screen
[18:25] Johnny: you can see from this link here:
