Re: Anamorphic Projection Theaters

Hello Mark, I have been through the DIY anamorphic thread on DIYAudio, yes all 184 pages, and have 4 wedge prisms. I haven't made the lenses yet but am finishing my 5'X12' screen and have been using the zoom on my Sony HS20 to fill the screen. So far I am very happy with the picture and am sure it will look better with the lens. I plan to do 2 lenses, 1 for horizontal stretch and 1 to compress for 4X3 material. I have my NHT speakers behind the screen and dipoles on the side with 2 more in the back for a 7.1 setup. My sub is a DIY unit 2' high & 12' wide with 2 18" drivers. It serves as the stage for my screen. My room is 16' X 25' with the sitting about 15' back from the screen. I hope to get some pictures soon.

The rest of my system
Denon AVR988
Toshiba A30 HD-DVD
Samsung BD-c5500 Blu-Ray
Behringer DCX-2496 Crossover
ADA MPA6 5.1 power amp
NTH Speakers (7 2way, and 2 10" subs used for mid bass)

Re: Anamorphic Projection Theaters

I have a website with a bunch of photos of Anamorphic lens installations. I mean no commercial intent so I am trying to post a link that leaves any other links out and goes straight to the photos:

Edit:

Well, after looking at my photos link, I figured the mods would see it as advertising, so I removed it. If a mod want's to pre-approve it let me know. I think the members would like to see the samples of other's installations, but they are on a commercial site.

It's too tedious to link each picture and remove any that might be construed as commercial individually.

But here's one of my favorite installations anyway:

This topic is best discussed back at DIYAudio. There is also a DIY lens thread here so I might quickly explain there.

In the past 8 months, I've also built a new HT room with full light control and thought I might share if that is OK.
Looking back toward to the projector

And the front of the room

I have also attached the link to my blog which has more pictures.

Re: Anamorphic Projection Theaters

Nice job Mark. I was just talking to my wife this weekend about redoing the lighting in the theater. Right now I'm working on moving my Denon AVR988 to the bedroom system.

Hi Prof, they are actually Bipole, so no chance of phase errors between speakers. I do however want to change them out for dipoles as I think dipoles will work better in the small room.

Thanks TwisterZ. The lighting is the most simple and cost effect thing I could find. It is just an LED rope light, yet works well to provide low level ambient light.

I have a fairly small room as well and I'm using DIY Tripoles in a 5.1 system..
They give me very good all round surround sound..

I originally had Dipoles and they worked really well (for 5.1), however I changed them to Bipoles when EX was introduced due to the acoustic errors that can arise. As it turns out, this is not hard to fix, however did cause allot of industry confusion and why THX introduced the idea of direct radiator for the back surrounds. Now that I am fully aware of how to solve the acoustic issue, I won't be worried about making the switch back to dipoles.

Also at the time, I was caught up in the Hi-Rez MC music hype when I made my surround change, so went with Bipoles because they represented one of the best compromises between direct (for MC music) and diffuse (film sound) speakers. I don't listen to that much MC music anyway (only have about 20 titles) so will be quite happy with Dipoles.

Tri-poles are an interesting concept though.
