Eugovector please be blunt!!! :help: lol

I did shrink the screen down last night this is what I have figured I would go with last night, just was drawing it up.

My viewing distance currently is going to be approx 9 feet on the first row and about 12.5 feet on the second row. According to Myhometheater if I make my viewing distance of the back row for 13 feet, I should have a screen size width of about 100 inches? This calculator below is for 16:9.

Viewing Distance/Screen Size

Correct my math if I am wrong please, to calculate the height of my screen I would take the ratio’s:
2.4/1 = 2.4: I would take 100”/2.4 and get a screen height of 41.667”
16/9= 1.778: I would take 100”/1.778 and get a screen height of 56 ¼ “
4/3=1.334: and for this one I think I would shrink the width to fit the 56 ¼ “ height. That would give me a width of 56 ¼ * 1.334 = 75.0” correct?

Is that more in line with what you think is more reasonable? I want to put my rear speakers and side speakers in pillars so they are hidden, put a nice rope light on the ceiling in a alcove/wane scotting?? if that is the correct term. Also I want to create a star night sky with some fiber for the center ceiling, I want to surprise my wife, she knows I want to do the star night sky, but what I have not told her is that I plan to do the night sky the same as it was the night we were married. :whistling:

Learning this 3D program so that will take some time yet to create and finish it. The God seat as you call it is the one at 12 feet in the middle but its pretty close to the back wall. Here are there screen shots of what I have so far.

The Door swing on the above object for the front door will go out and not into the theater.

The head position in the first row is at about 9 feet, and the head position in the second row is about 13 feet from the front screen and just over 3 feet from the back wall, so I guess that is not so bad. I will most likely be moving the door to the back room next to the equipment rack so I can put a base trap or what ever is needed in both corners.:hsd:

Re: Phase 1 -- Planning

Will you be sitting in the backrow or the front row?

PS: "god seat" was supposed to be "good seat", but this fingers can be slow at time. That being said, I like the term, accident that it is.

I like being higher up, so I would assume the back middle seat. I could push the screen back and build the center channel and put it above the screen or below the screen with the towers to the left and right and build it out more like this one but not sure if it would look funny with the screen set in closer to the back wall and have the sides built out. I would not need to go the full 30" I guess on the build outs since I don't need to worry about the speakers interfering with the AT screen. I just really wanted to put some lights behind the screen and light the speakers up behind for a show piece. Still thinking, planning. Really open to suggestions from the experts ;) and blunt is ok as well. Kind of like when IMAX shows their speakers behind their massive screen...I would just like mine on a much smaller scale lol.

Hope that above paragraph made sense.

Re: Phase 1 -- Planning

The front center seat will be the best in the house in terms of surround and general audio performance.

You've taken a big step from 10' wide to 100" diagonal. Somewhere in between would still be OK.

If you're going to build any kind of enclosure for the are behind the screen, I would highly recommend that it be only framing and cloth - no hard surfaces or you'll have a big problem on your hands.

Also, just for aesthetics, I'd take the far side of it all the way over to the wall. Just my 2 cents on this one.

Yes, and fill it with insulation.

Re: Phase 1 -- Planning

Keep in mind that you'll want easy access to the space behind the screen. Plan on building a door in the back, or to the left hand side of the screen.

That screen size calculator will work great, but I agree with Bryan that you should anticipate the front row middle will have the best performance (and you don't want you head right by your equipment rack because of potential noise). If you like being higher/screen lower, you can lower the screen, just keep in mind that people sitting in row 2 will need to look over heads, so a taller riser may be in order.

Unless I'm seeing wrong 100" is your planned width, and 116"" is your planned diagonal? Just keep it around THX specs and move your rows until you are happy with your layout. I'd shoot for as big a screen as possible using the middle front as the sweet spot, while still not having to push your rows so far back that your 2nd row is up against the wall blocking access to your equipment and giving them a poor surround field.

Re: Phase 1 -- Planning

If you build just a stick frame and cover with cloth 'grilles' attached with velcro to the framing, they will be easily removable for access behind the screen as a side benefit of that type of construction.

Good call.

Re: Phase 1 -- Planning

Here is an example of two room that I may pattern mine off of. They have the black frames up front like you suggested which should give easy access behind. I will make the roof much more interesting then these two, but I like the wall treatments and I think it will help with the noise reflection?

I want the wall's more then just all the same sized squares, maybe make it duo tone panels and create a neat line or two in it. I want to add some pillars, but don't think there is room to add one beside the walkway that goes to the back furnace room.

True, your reading it correct I a shooting for 100" to be my screen width. I have a DIY solution for a AT screen that looks promising.
