I was around best buy and I noticed one of the hone theaters they had for display. It had a nice projecter and chairs too. You can feel the sound. I'm just curious as to how much does such a thing cost. How much would it be to keep/maintain it?
Answer
There is no fair way to answer this question because you can spend as much or as little as you want. The range is literally from a few hundred dollars to a few hundred thousand dollars or more. You would have to decide what you want to spend the money on depending on what your focus is.
You can get pretty nice theatre seats for about $600/ea, there are more expensive ones and cheaper ones so maybe you would rather go with less expensive chairs to allow more funds for audio or video components. The screen depending on size and quality can cost a few thousand or you could opt to save money on this by building your own. You can get bulk Da-Lite screen material from Cousins Video. http://store.cousinsvideo.com/cut-to-size.html You can build a three or four thousand dollar screen for a few hundred dollars.
You can get an AVR for as little as a few hundred dollars but the quality of these really leaves a lot to be desired. A better quality but more expensive option would be to buy a preamp/processor plus external amplifiers. This can get really expensive but personally I don't think you need to spend more than $10K on a processor to reach a level where spending more would gain nothing. You don't need to spend more than about $2K before you reach a point where spending more diminishes rapidly. For power amplifiers, there is a dirt cheap option in a company called Emotiva http://emotiva.com/xpa3.shtm For the money these are really hard to beat. A good compromise is to buy a nice AVR with preamp outputs in the $1000 range then buy something like the Emotiva 3-ch power amplifier to power the left/right/center speaker. This frees up the AVR's power supply to power the surround speakers very effectively.
Speakers is the most difficult for me to make suggestions. There are very few commercially available speakers that are very good at all in my opinion. I've been designing and building my own for decades. There are a bunch of typical mass market brands that are recommended here on Yahoo all the time but in reality none of these are any good. One of the favorites is Klipsch and while I would never want these myself, they do have the advantage of higher efficiency than some of the competition which means you need less amplifier power which in turn means you are less likely to distort your amplifier so the net result is that they may work better in a typical mass market system especially if an AVR is used to power the main and center speaker. If you really want astounding dynamics however you need something a little more substantial like commercial grade cinema speakers or my favorite, some big floor to ceiling line arrays. The commercial cinema speakers are relatively inexpensive, maybe a little over $1000/ea.
The best subwoofers are custom DIY designs. Outside of that there are a couple brands that make some nice subwoofers. SVS and HSU make some of the best commercial subwoofers and are not terribly expensive, around $2000. Emotiva also makes some nice subwoofers for the money in the few hundred dollar range. If you can do DIY yourself you can save money but if you have to find someone who knows what they are doing to do it for you it will likely be more expensive. One big advantage to DIY is that there are no limitations. You can make what ever you want, enough to structurally damage your house if you want. If you really like to feel the room shake with movie sound effects then that's the route to go.
You can also get bass shakers to attach to your chair but from my experience these are pretty lame. They tend to operate only at too high frequency, perhaps 30 ~ 50 Hz. They buzz more than they shake. I would rather just have the woofer capacity to shake the room and not need bass shakers.
Best Buy isn't the place to buy a high end system. You need to find an independent high-end audio video store in your area and let them show you what's possible.

THE ULTIMATE HOME THEATER QUESTION(s)?
BRAVOSIX
So me and a buddy are planning to build this huge theatre in a part of a warehouse he owns near our houses. im not got gonna get into details into that. Were talking about movie theater sized screens, about 30x70 ft. We have found a projector- http://pro.sony.com/bbsc/ssr/cat-projectors/cat-digitalcinema/product-SRXR320P/.
But we have one problem. The audio system. And no way in hell are were gonna put in those little receivers. Im talking movie theater quality. Suppose we wanted to connect a blu ray player( dont worry sony is gonna release a 4k player this year), what exactly will we need to achieve theater quality sound with multiple speakers and what not.
ALSO
where does one find the projector screen that movie theaters use( the big ones)
and
in movie theaters are the screens slightly curved or straight?
Answer
Some theatre screens are curved, I curved my HT screen with a 42" radius. It's only 144" diagonal at 2.4:1 aspect. You're going to need to find a commercial cinema company to provide the screen for something like this. I made my own screen but at the size you're talking about I certainly wouldn't want to try it.
As for speakers etc you can go with the same stuff the commercial cinemas use... http://www.jblpro.com/products/cinema/index.html That will get you the same quality you get in commercial cinemas which unfortunately isn't very good. For more money and a lot more work you could build some big CBT arrays http://www.xlrtechs.com/dbkeele.com/CBT.php that would blow the JBL Cinema speakers away in terms of sound quality. You would be able to build these custom as big as needed to get the performance you want. This would be dramatically better sound quality than the JBL pro cinema.
You definitely don't want the JBL pro subwoofers. Their idea of low bass is 25 Hz but for the real movie experience you need a lot lower than this and you need it with a lot lower distortion. My HT is just 19' x 27' x 10' and I use twenty four high excursion low resonance 15" woofers to get very effective output to about 13 Hz. The current woofer system is open baffle dipole but I'm working on ideas for installing an infinite baffle system capable of single digit Hz. I just picked up some 29" bicycle inner tubes for making the surround edges of the custom woofers to be used for this project. If this project works you could do something similar otherwise you're probably going to be stuck with commercially available woofers. The problem with this is that the distortion and noise are too high in all of them. The ones I use are these... http://www.parts-express.com/pe/showdetl.cfm?Partnumber=295-468 These are not bad if you use enough of them. If you put them in large sealed boxes you might could do pretty well with perhaps fifty or sixty of them. The problem again is just that the distortion and noise is too high so you need a lot of them so you can operate them at a fraction of capacity in an effort to keep the noise and distortion at a minimum.
If you're putting together a theatre of that magnitude you really owe it to yourself NOT to use commercially available speaker systems. Go with the custom and I highly recommend the CBT array approach. This is the best means thus far at controlling loudspeaker directivity so it will help reduce the need for room treatment. Also, overkill is a key element to having the really "Scary" dynamics. I'm not talking about loud, I'm talking about instantaneous transients... leading edges to concussion waves from movie effects that will have your audience just about jumping over their chairs backwards. Also, low frequency rumbles that you can not hear at all but can feel... you don't need bass shakers in the seats! Most woofer systems have too much distortion to achieve this, they might be able to produce the subsonic frequencies but not without a lot of harmonic content that ruins the effect.
