Re: Building a Home Theatre Room

Hi CMS,

Thanks for the detailed feedback. Here is my points:

How much distance will suffice this requirement ? I currently have about 2-3 inches gap between the speaker and the wall.

The right side window has a sound absorbing bamboo curtain and requirement of some sort of similar setup is what gave me an idea of Mural painting on the left side empty wall. Hence the question, if Mural painting will have a better effect or will it play spoil sport ?

- Move the sub into the room. You can do a "crawling test" to find the best location.

With the above two itself, you will get a better soundstage and channel separation.
I will surely try achieving this suggestion, however can you elaborate what is crawling test ? how to perform it?


Thanks in advance for patiently helping me on this regard.

My suggestion for a new thread is because its another user's HT thread and the all the posts are specific to his design and build details.

As a starting point you can use the Cardas Audio's recommendation for a rectangular room, .276x from the side walls and .447x from the back wall, x=width of the room. You can also consider the Rule of Thirds along with this.
My cousin's living room setup is exactly same as your's. What we did was to place the speakers ~5' from the back wall and ~1ft from the side walls along with a 4" deep sound absorbing material (600gsm Synth wool + wood wool board) on the side wall to cover the mid and the tweeters. I think this is the best in your case.

Sound absorbing bamboo curtain? In which way? It wont absorb anything than reflecting. Also any painting will have a reflecting surface.

Hi Trammway,

Did you import the Onkyo TX NR 1008 ?
Just wanted to know if you carried it yourself, or had it shipped via any website.

If its the latter would like to know the details, price etc..

Ps: I currently have a Denon 1713, but not happy with it. Looking to upgrade to an Onkyo TXNR 727.

TXNR 818 is quite pricy in India

Btw I have a basic HT setup, however dont have the luxury of a dedicated room, so the hall doubles up as the HT room

Thanks
Fillmore

There is no drawback in having the setup in the living room or any benefit in having a dedicated room, but luxury, yes. Both environments can be controlled, but in a living room with some limitations due to aesthetics, but a clever designer can achieve to an extend. Only problem with living room in most of the cases is the light control for projection during day time.

Thanks mate.

Ok, I will have to find a different location for the wide speakers, removing them will automatically introduce 1ft gap in the side. Let me see how could I insulate the rear with some sort of sound absorbing material in a short while.

I have imported Sony STR-DH520 3D 7.1 and Onkyo 1008 from USA in different route at a different time.

I carried the Sony STR-DH520 in checkin baggage and no question asked at Chennai customs. I didn't have any original packaging just wrapped it with bubble wrap and put it in the bag and it safely arrived at Chennai. I'm kind of thinking to get rid of it now as I have upgraded to Onkyo 9.2 channel one.

When I was transferred back to India, I carried lots of stuff in a container (200 cubic ft) and all the speakers (except the Center CSI A6) were brought in the container along with the TV, AVR, Player and some other items. The customs clearance costed me around INR 18K for everything and shipping was $1800(door to door). The only downside of bringing from US is that it requires a step down transformer and there are high chances some one may burn few electronics by plugging in to 230v wall socket. (Lol, I did burn few adapters already)

I don't have a dedicated HT room as well, the picture posted above was my living room. (13ft width x 27 ft length)

But you are still not avoiding the corner loading, which is the worst thing and should be avoided. The ideal position would be the left speaker after the door opening and the right speaker at the same distance from the back wall. A slight toe-in will also help in reducing the first reflection and good for getting the sweet spot. Since the speaker sides are very close to the wall you have to provide a 4" thick sound absorbing material. Treating the side walls are more important than the back wall for a horizontal soundstage, back wall is for better depth.

Re: Building a Home Theatre Room

The room which doubles as my HT room is due for painting.
Wanted to find out if its a better idea to go in for painting or fixing wall paper ?

I don't plan to do any actual "Sound proofing or dampening" treatment, but given the choice between paint and wall paper would the wall paper provide any advantage ?

Would appreciate any inputs on the same.
