    Hello guys

    Finally I managed to persuade my wife to give transform our "room for random stashing" into a home cinema. I have some experience with stereo setups so i am really looking forward to dig into the world of surround sound.

    I am on a limited budget however my plan is to achieve the highest 5.1 cinema experience possible with what i have got, so much of my equipment is bought second hand.

    I plan to run all of it through my computer with XBMC (preferably my 2011 mac mini) and i also plan to use dirac live room correction as i have had very good results with this on my stereo setup.

    So far i have gathered the following equipment:

    Receiver : Integra 80.1
    Source : Mac mini 2012 running XBMC with dirac live
    Subwoofer : XTZ 12"
    Projector : BenQ W1000
    Screen : 90" gain 1.0 roller blind, cut out and fastened to screen frame
    Speakers : Not 100% sure about this but I am currently very interested in the upcomming xtz cinema series

    Here are some pictures of my plans and some of the stuff

    Had to test how large 90" would look :)

    The chairs. Even though i only need 4 seats i bought 8 to take the 4 best and resell the rest

    Great work so far! What's the dimensions of your room?

    I'm guessing that's a corner bass trap right? Nice idea.

    Are you planning on just the one subwoofer? Try the REW room sim software to estimate your likely in room bass response....if you haven't already.

    Looks fantastic! Your centre speaker really should be the same height as your left and right though :)

    Of course you'll need an acoustically transparent screen for that so here's a thread you might enjoy on how to build a cheap (but excellent quality) one:

    Sorry for the late reply guys and thank you for your comments


    Right, the plan was to have corner traps in all corners and the wall behind the screen wall have been covered in isolation material. But i decided to only go for traps on the back wall and then cover all sides behind the screen wall. Perhaps i will make traps in the front as well if necessary. You can see the revised layout below

    Room size is 4,5x2,9 meters so it is rather small.

    I have looked into REW and used their sub woofer simulator. That has convinced me that 2 sub woofers are the way to go so i will place one at the center front wall and one at the center back wall.

    Thank you so much for that input!

    You are right, i would love to be able to put all 3 speakers at the same hight but unfortunately that is not possible at the moment as i have bought a normal non-AT screen.

    But that will be a future upgrade for sure and thank you for the spandex link. I will defenetly look more into that. Thanks!

    Time for another update :)

    A lot has happent since my last post and i the room is now at a stage where it can be taken into use.

    I have moved my livingroom stereo speakers into the cinema room and have done a bit of testing. I have come to the conclusion that my screen is not good enough and has to be changed - and i have listended to your suggestions and ordered a Seymour UF audio transparent screen. The old one will be taken down and the new be put up during the next weekend.

    I have also decided to put up another row of wall panels as there still was some flutter echo when clapping at the listening position.

    Here are some pictures

    Looking good. Are the chairs comfy? Just curious as they look like cinema ones.

    Also, your pic shows your centre speaker laying flat. You probably already know but I your lcr should ideally all be the same height :)

    Hi Herbiefish

    Thanks!

    The chairs are from a local theater and compared to the nice recliner leather chairs out there they are not that comfortable - especially the arm rests are a bit too short for my liking. They will be replaced in the future for sure - i just need to find a way to fit in a row of 4 chairs which is a bit hard for my small room.

    You are right, the center is laying flat and it is a point i am struggling a bit with atm. My plan is to invest in the upcomming XTZ Cinema line

    XTZ Cinema Series - Compact hifi cinema experience.

    According to my original plan they are a perfect patch as the center is designet to fit under the screen but now that i have invested in a AT screen it makes things a bit more difficult. I am thinking about making a cradle for the center so that the tweeters are at the same elevation

    Amazing, congratulations! You have a lot of treatments in there, do you find the room is live enough as I don't imagine you get many reflections?

    I ask because I have a similar size room and I'd like to use a similar number of treatments!

    Also where are you based?

    Thanks a lot guys, I am quite happy with the way it turned out.

    @pingpong No, i calibrate it myself with ARC on the anthem and then i go over it with DVE essestials and my radio shark db measurement tool. I like ARC alot - it was also the reason why i went for the anthem instead of keeping the integra. I like being able to control the low end with EQ without messing with frequencies above 500 HZ. For that i use room treatment

    @sims. I have felt in some occations that the music in movies could sound a bit dull as the room is damped a lot so i have changed the back wall absorbtion into diffusion. I am considering to keep the first reflection absorb panels and change the rest to diffusion however i am also a bit afraid to trade the well defined details i got after making the baffle wall and added the absorb panels for more ambiance...

    I live in Denmark

    Eotas, I love what you have done! My room is under construction and is about the same size, I've bought the XTZ cinema series btw.

    May I ask what colour you painted the walls and whether you're happy with the reflections? Are you considering velvet/devore type treatments.

    All the best

    Hello Indus and thanks a lot!

    I am sure those XTZ cinema series speakers are gonna sound awsome, i was really looking forward to mine but i could not wait for them to be finished :D

    The walls are painted dark grey. Optimally i would cover the wall with some black fabric. However as my room is very small, i try to keep as much of the room area as possible. Thats the reason why i went with the wall panels

    Eotas what is the Klipsch in wall speakers like. I am thinking of building a false wall myself with the speakers inbuilt. Would you recommend them?
