Help with my home theather set up

[Raltron]

Happy new year to all, I joined this forum looking for some help and ideas, I did some remodelations and end the project with the following space or area: 158"L x 123"W, the cealing is 131" tall, as you can see I have a enormus wall, what will be the perfect size for TV and the corresponding furnitures for my effective area?

I can hide the AC, AV cables under the concreate "bricks" wall, I like to use the grinder with the diamond wheel, will use a 3/4" PVC flexible conduit, also the speakers cable needs to be hidden as well. Any ideas where to start?

Thanks in advance

So roughly a 10’ x 13’ footprint. For acoustics reasons you’ll want the listening position about 8’ feet from the front wall, which is right about where you want the viewing position to be for about a 72” dia. screen. You could go up to about an 84” dia. screen and still have room for the front L/R speakers. For this size screen you’d want to be back about 9’, which won’t affect the acoustics too much. Again for acoustic reasons, you don’t want the listening position any closer than about 3’ from the rear wall. So if you don’t want a projection/screen setup, you could have something like a Mitsubishi 73”/82” DLP RP TV, push the L/V position back, up to 2’, and be okay.

Thansk AVRat, for your tv size advise, now I have to look about what TV furniture for my tall roughly wall of 11' x 11', I saw in Costco some In-Wall units, all attached to the wall, they looks to be wood, a dark color, no legs or stands touching the floor, the unit looks not to fit my effective area, 11' x 11' wall, or maybe have the idea of this and bulid my own custom In-Wall unit to build in or fit my new 73" dia. screen

Thanks

FYI, the 73" Mitsubishi I mentioned is not generally wall mounted. If that's your interest, it would take a fairly robust, deep shelf to support it. See dimensions here: http://www.mitsubishi-tv.com/pdf/dimsheet-WD-73837.pdf

For the largest, somewhat affordable, wall mountable TV, then perhaps a Panasonic 65" Plasma would be a better option. Even with this size at 8' viewing distance, the HT experience is still quite immersive.

Hello my friend AVRAT,

In the same area I used to have and still have a 42" dia. screen plasma tv, but it was installed in the width area not at the lenght, that means more closer to the audience. Is there a formula to select the TV dia. screen? depending to the area and distance?

I still have the 42" Panasonic plasma, but I'm not sure if is the right dia. screee for my new wall, I used to have more area in the same family room but the laundry and some storage were at the end, so I desided to install a concreate wall made of bricks, then covered with plaster, this was to isolate the laundry from the family room, this is the new wall with the dimmensions I mentioned before.


What about the furnitures? or TV wall furnitures, do you have some ideas according to your experience?

Take care

http://myhometheater.homestead.com/viewingdistancecalculator.html is referenced quite frequently as a starting point. People’s viewing perception vary widely as you see in a theater, some sit closer, some sit farther from the screen. For a decent mix of TV/movie viewing a good rule of thumb is 0.5 x viewing distance = screen diagonal. For HD movie centric viewing a 0.75+ multiple is more common. Myself, I prefer about 0.67.

I’ve never wall mounted a plasma, let alone on a brick wall. I’ve read of people using anchors for brick/concrete walls with good results. There are plenty of wall mount options available for the flat screen panels. Monoprice.com offers some good quality inexpensive accessories.

What other type of gear/accessories/furnishings would you like help/info with?

Just for reference, the THX minimum included viewing angle is 36 degrees field of view. Where you go from there depends on your preference as a front, middle, or rear of the theater kind of guy.

I've wall mounted plenty of screens to brick/concrete - for the price of a cheeseburger and fries he can get a box of tapcons that will be capable of suspending a small pickup truck if he so chooses. Only limiting factor at that point is the tensile strength and max load capabilities of the mount itself. If he can find one that supports the weight of his TV, he'd be all set.

I think viewing distances and screen size are more forgiving that proper seating position based on audio interaction with the room.

Generally, the display should be on the short wall for better acoustics.

And, as suggested earlier, 8 feet from the display is about as far back as you want to sit. This is critical because too far back and you will get too much bass reinforcement from the rear wall. Sit too close, lets say 6.5 feet, and you will be sitting in the center of the room which usually is a null area within the room.

Keep these in mind and the video display size and distances will be much easier to accomodate.

Good luck and keep us posted.
