Axiom Home Page Forums General Discussion Technical Questions center channel placement

It is a few inches from the ceiling and I'm using turnbuckles so I can dial in the required angle aiming at the seated listeners' ear level of the second tier.

The ceiling and walls are all black, the speaker is black and I painted all the hardware in black. Regardless of the lighting use a decent photo is not possible.

JC,

that means you don't use a bias light behind the TV? i'm surprised.
there is a very good thread about this in AVS Forums.

Using a front projector you need to completel yeliminate all possible light sources except the projector of course. Ideally, you should not be able to see your hand in front of your face when the lights and the projector are off.

I believe one of us on the customer counsel asked Ian long ago before the 180 was released and Peter was in charge of the calls, about suspending it upside down using the existing threaded inserts. I believe the answer was no problem.

Later info from Axiom said that was a bad idea. I know that someone talked about it on the call, but that was apparently inaccurate info.

hmmm, guess I missed that. I would assume using threaded hardware with appropriate strength, I see JC mentions turnbuckles? for his setup it should work. I guess you would have to trust the inserts would not pull through the mdf.

In regards to lighting, bias lighting has been discussed on this forum. I would never use that behind my screen, like some use for TV's, however, I disagree with JC in regards to having no ambient light anyware in the room. Idealy, there is nothing wrong with having dim lighting behind or off to the sides, not affecting your direct view of the image. Even professional theaters have rope lighting, and other dim ambient lighting. Try looking at a remote with only projector light.

To have or not have any ambient light is a matter of personal preference and what you are looking for in your HT. If you are trying to create a “Movie Theater” like experience then some ambient light is necessary. However, if you are looking for the best possible picture quality and immersion (suspension of disbelief) then total blackout is the way to go. My preference is total blackout, but it’s not for everyone.

The need for a bias light diminishes as screen size increases. The problem with a screen that doesn't completely fill your field of view is that it tends to act like a flash light beam pointed across the room right into your eyes. With larger screens you don't have that large blackness with a small bright light in the middle.

Thanks for that info Chris. I always wondered why I never get a headache watching my projection screen 16 hours a day all weekend when my 56” HDTV would give me problems in just one day. I always thought it was the distance and the fact that I’m loosing my near vision.

Keeping Newf's VP150 falling off the wall experience in mind (but primarily using my own common sense) I'd personally be very reluctant to hang a $720, 56.8 lb speaker straight down from the ceiling using four small threaded into MDF inserts.

But that's just me.
