What is the ideal square footage for a very nice home theater?

I am interested in building a very nice home theater (I would like to spend between 50K and 200K). Could I build this theater with a square footage of between 500-750?

Yeah, right, you are going to spend $200K on a home theater based on advice you get here! LOL Don't waste your time, or ours.

If you really have the bucks and the desire, go to a professional audio-visual store and get professional advice on equipment and what should go into construction. Believe me, if you are going to spend $100K on their equipment, they will fall over themselves trying to help. Easily. You can easily build a small home theater beginning with 300 sq. ft. [15 X 20 ft.] - which would cost well under $900. And here's a brief do-it-yourself set up for a front projector casting a 92" diagonal image on a painted wall screen.

If you are looking for the best do-it-yourselfer home theatre, it would consist of:

1. Your current two hi-fi stereo front speaker system [without need for a third channel speaker since you do not want to upgrade your older hi-fi amplifier to handle digital surround sound] placed just below your TV viewing screen. Cost: $16.00 for extended quality audio wires for across-the-room connectivity.

2. One Infocus ScreenPlay [SP] 4805 DLP front projector [click on the "Picture" link for a home theatre image]* casting a 92" diagonal 16:9 high contrast [2200:1] image placed on a coffee table. Cost: $580.00 for a refurbished unit; replacement lamps sell for $330 and last some 3,000 to 4,000 hours. *Picture of actual home theatre setup showing "A Good Woman": http://ec1.images-amazon.com/images/g/01...
