hi paskal.......pending for DBKL approval.
architect submitted entire house reno to DBKL.....

so yeah pretty much i would say the 16' x 27' is confirmed.

skeelee.....i wished i have the opportunity to put my audio speakers behind the screen......however don't think it is possible....
unless i shift the screen to 5 feet away from the wall.....hide the audio and HT speakers behind the screen, which will block sound from my audio speakers

Cardas golden rule is a yes and no thing....

if following Cardas's rules

my speakers required to be 7.152' feet from rear wall and 4.4' from side wall......that's going to be a challenge for the screen.

120" screen, 15 feet away will only give you 32.7 degrees fov at the first row and only 24.8 degrees at the second row. that is if you're planning on introducing a second row. i would, especially with that length.

thx suggestion that i've read around is to keep 36 degrees for the last row. and like skeelee pointed, sweet spot should be around 45 degrees and 50 degrees maximum for the front rows.

hhhhmmmmm u guys r right......and perhaps mixing d audio with HT is a bad idea?

Not really. Is also depend on your expectation.

it's a good idea. i'm planning such an implementation.
rough drawing in sketchup i think you could separate the HT setup and audio setup in the same room. just ngam ngan fit for separate audio speakers without blocking the view.

to calculate a good ceiling height, put your nett room dimension into this to calculate room modal distribution:

you might wanna put your room dimension and listening position into REW room simulator.
it's so accurate, it's scary.

my current room:

the actual measured response:


read around on the net, people are also saying the simulator is pretty darn accurate.
it accurately predicted the peak at 35hz, the null at 40 and 50hz and the large peak at 60-70hz.
null at 80, peak at 90, then null at 100.

overlaid. not to scale.
but check the pattern.

focus on the <120hz because i've implement an lpf filter on the sub.

pretty darn accurate i'd say. because there's a large closet at the back of the room. the simulator needs a rectangular room for calculation.

Very impressive there. If the room is near square, how the REW accuracy will be affected?

not as bad as i thought it would be.
let's say 10'x12' as per most second room in most houses would be. with 9' ceiling.
92" screen, mounted at the wall, listening position 9 feet away, 40.6 degrees field of view.

single sub, center of the room


dual sub co located at the corner. improved the room response somewhat.


the null at ~100hz is because of the listening position 3 feet away from the wall.
1130/(3*4) = 94.16, room mode plus boundary reflection at that area causing a huge null that's hard to correct.

interesting

Hushymushy... if u want to put speakers behind screen.. get a perforated screen... then OK...

elhefe.......sini you pun ada....
nampak giler hifi gear in your place man

yeah thinking about that......but tested it at a couple of places....the sound seems mellowed

Hushymushy... di mana ada racun hifi... di situ saya ada hahaha

My gear basic only.... dream of having projector shattered... due to hall limitation... frust...

With proper amplification and speaker... sure ok one putting speakers behind screen.

Whenever you are free... come over lah... looonnggg time didnt see u....

Hey bro....yeah man....long time didn't catch up
Last we meet was almost 10years ago!!

i dunno if this is being discuss before
can we setup a 3.1 system? a pair of front + centre + sub? or
better to setup a 2.1 system? movies more than listening to music
setup in a living room and surround installation is a problem

Yes you certainly can for both. Is just personal preference

I need to buy a home theatre system as my current one seems to be faulty... Its a Sony one, cant remember what model.. bought it like 8-9 years ago...

Do you have any recommendations? I would probably need to buy a new tv too as my sony bravia looks like gonna crash soon...

Please help...

of course. 3.1 is better as it give a more firm "middle stage" in movie dialogs.
u can achieve surround feel by changing the facing direction (toe in toe out) of left right speakers

Wah! Really humble. That also considered as basic.

max, his new room gonna be awesome!!..
he has a capable hifi lover contractor
