I have Dipole on sides with direct radiating in the rear. Currently the rears are at THX recommended real close, on either side of my projector about 18". I prefer having them half as wide as the fronts.

Tri-poles are good at reducing the null effect at the listener position that you get with Dipoles..
With a front firing woofer and the forward and back firing Mid/highs, you get a more encompassing surround sound..and I've never felt the need to go to 7.1..

I took a look at the M&K tripoles a while back. The idea intrigued me, however at that stage, it would have meant a total redesign. The new surrounds will be something new, however I get to simply recycle the drivers I currently own.

7.1 is amazing, especially fully discrete stuff on BD. THX Cinema 2 processing also does a wonderful job of 5.1 and 5.1EX program.

Now that I have finally finished my screen wall I thought I should finally contribute to the thread.

The screen is a 130" (diagonal) scope screen, which I think is 3.03m wide x 1.28m high. It's 850mm up from the floor (740mm off the stage)

The front row sit about 3.4m back from the screen, the second row around 5.2m on a 440mm riser.

Screen wall

I'm still waiting for my projector to arrive so will post some photos and screen shots once it's all setup.

Cheers,
Simon

That's a nice size screen Simon...You forgot to mention that it's an AT screen! :D
Do you have any other shots taken from further back, to get an idea of the room overall?
Agreed. Very clean.
Thanks guys!

Whoops good catch Prof :T

I do have a pic from the back of the room but it's at home. I'll make sure I post i tonight :T

Cheers,
Simon

i've heard those are pretty expensive. as far as manually zooming, what exactly does that involve. would i be simply adjusting the lens by turning it somehow. just curious the amount of work that would be needed when someone talks about manually adjusting

When you manually change AR's, you would select 2.35 on your remote ( if you're changing from 16:9) and manually zoom the image to fill the screen..and sometimes you may need to refocus..and it's not always easy to just fill the screen and not lose some of the outer image onto the borders..
Generally it's a pain..and particularly if you need to change from 16:9 to 2.35 and back to 16:9 AR during a movie night..

There are more and more projector makes that are now including auto AR's..My last projector has that facility and I'm now able to do away with the anamorphic lens..

On my projection system, it takes less than 30 seconds to adjust between aspect ratios. That includes adjusting the zoom control ring, vertical lens shift knob, and moving the drapes for masking. Focus is stable when zooming on my projector.

Vertical lens shift range will vary, depending on projector placement. None at all is needed if the lens is located perpendicular to the vertical center of the screen.

The wall behind the screen should be painted black or very dark. Black bars on letter boxed Blu-ray Disc movies will project onto the wall above and below the screen, which can be distracting if the black levels on the projector are not good enough.

The lower cost JVC D-ILA projector model still has excellent blacks, plenty of motorized zoom and shift range, plus lens memories. Last I checked, the less expensive Panasonic LCD projector is similarly enabled. The Epson line may also include a candidate.
