Welcome to the Miyake Theater.
Have an ale and some hot popcorn while I pop in this new dvd.

Let me tell you abit about it.
The whole theater is pretty much DIY. It has been done as economically as possible with parts built by
me, bought used on auction, and repurposed as much as possible.
The room is 13' wide by 20' long.
The screen is 108" diagonal.(92" x 52" 16x9 widescreen)
I have constructed a DIY pair of subs based on the Almighty subwoofers,(a design by Stig Erik Tangen) using
JBL 2226g concert 15" woofers. The enclosures are 6' wide (black coffin sized boxes) which run all the way across the front
of the room.The subwoofers are powered by a NAd 2700 amp. It is only 100 watts per channel,but has good headroom and completely
shakes the whole house.

The projector is a Sony 1272q professional conference room projector. This type of 3 crt projector (Barco, Sony, NEC) is being
replaced in business use by the newer lcd projectors. So they can be had for a very good price.

This video image is being processed with a Focus Enhancements Quadscan Scaler. Which I purchased used.
It is a fine processor, but perhaps a bit soft for the Sony, which tends to also be just a bit soft. I haven't tried other
scalers/quadruplers but I have compared the Quadscan image against the DVD progressive output, and DVDO pro line doubler,
and the Quadscan is definitely superior.
The image has a very filmlike quality, and a good amount of depth. On a screen of this size, the quality
of the DVD has huge effect on the picture. It may not be noticeable on a standard tv, the the clarity of DVDs runs the gambit.
Pretty much everything I have learned about Projectors, processors, and home theater, I got from the AVS
Forum web discussion group.

I have a Yamaha 1095 receiver. Which is 5.1 Dolby Digital and DTS. This is old hat in the day of 6.1 and 7.1 receivers. So
I have improvised my own 6.1 by using an old Kenwood ProLogic receiver. By taking the left and right rear signals from the
main receiver, and running them to the left and right input of the prologic receiver. The prologic receiver will then decode
a center channel for your rear center speaker!
Furthermore I am experimenting with using the sound processing on the prologic receiver to provide slightly modified discrete
versions of the left rear and right rear channels. Can you say DIY 8.1 surround?

The front wall has R13 fiberglass insulation, covered by dacron batting, covered by pleated curtains.
The walls are red mahogany stained luan plywood. (dig that flame) There is still some finishing work that needs to be done
molding...etc.

The ceiling is painted flat black. (I was worried about how a black celing would look, but I love it. Lots of bars and resturants
use it and it provides a intimate mood.)
Also with a ceiling mounted projector any light reflected from the ceiling, seriouly washes out the image on screen.
I wanted the room to be very dark, and man it is. Perfect for movies. Lousy for taking pictures, sorry about that.

I hope you enjoyed looking at my home theater.
Feel free to let me know what you think.
I like chatting about audio and home theater subjects.
