My bedroom setup.
Anybody knows where can I find a tall speaker stand to support my rear speakers?

Recently visited some VIP's home and saw some unbelievable setups
Sorry for not able to disclose name and post pix for their privacy.

Krell power amps from model 300 to 600 (i forgot how many numbers there - minimum 13 above)
Samsung 9 series 55"(at least 2 / 3 nos) just for CCTV and Astro only
Optoma HD81-LV & another (dun know what model) projector (at least 2 nos)
Morel center speakers (2 nos with around 10 speakers + tweeters per pc) - just put in store room)
ATC active speakers for surround (at least 5 nos)
ATC BIG passive bookshelf speakers (2 used as center - powered by 2 individual Krell power amp) & (another 2 used as front surround)
Custom-made side speaker enclosure with around 10nos of ATC drivers x 4 nos
Mirage floorstand - put aside no use - probably spare
Speaker cables only = easily exceeded RM200k - RM300k (MIT shogun with few boxes - so many pairs laying around)
HDMI - Kimber Kable, Wireworld, Van Den Hul ... all hi-end or reference series
Power cords = as thick as can drinks = few
CD players = Krell
Media Servers = dun know what brand but cost more than RM 15k
Mark Levinson ... Krell Pre-Amp ... Jadis Tube Integrated (size approx. 2' x 3' in size) ... Utopia Floorstand ... AudioQuest speaker & power cord (as spare cables only) ... Marantz SR8003 ... Mark Levinson AV processors ... blah blah ... blah blah ...
And so much more which i can't remember ...
The mini theater alone can fill at least 40 ppl

The above i saw with my own eyes and its local !

If you go to his house and listen, then you will feel that our setup is miles apart for music. His CDP already abt RM3.5K  Using Cardas Interconnects.

After auditioning, kena poison again. This time, maybe you will buy good CDP, nice cables, a dedicated stereo amp.

if square BOX room like 11 x 11 kaki

means langgar dinding 99?

mega,

11x11 it's ok la .. you just need some sound traps to balance back the harmony. I thought that my room was good enough but having people visiting once a while for audition, I find that it's better after comments and adjustments. my room is a bout 15' x 11' with one open alley, and I sit smack right to the wall. (this gave me a lot of disadvantages, but was able to counter with rear wall absorption panels. Can't rearrange on the other position as the sliding door is on the path.

but no ppl stand at corner all the way to watch the movie from begin till the end rite??

the boomii effect should be reduced at the target audience position?

no?

So does this mean all 4 corners should be padded?

how about put full ceilling height fabric curtain surrounding or at corner?

Later I post up pictures when I go back home. U can roll up any foam from packing material. The thicker the foam the better. The one I use meant for acoustic treatment.

Example of packing foam material is like this one my friend use as back support

Bro, so there would be 2nd batch of the acoustic foams? Great. A pair is not enough for my room as the 2 pairs were meant for my bro.

I have to fine tune my room. Btw, I am in the midst of sourcing those similar foams that Auralex use.  Just chat with the boss about it. I will take my Subdude to show him.

how to do the math...     

I've never tried those glue before thou, but the chemical should eat the foams I guess .. maybe I'm wrong .. hehe .. but dunlop on the walls .. sure permit tak lepas.

Sifu, how do you guys reduce/eliminate the echo sound in your precious HT room?  I can hear the high frequency echo sound when clapping my hands at the middle of the room.

I DIY some triangle and rectangle trap using Roxul MPS400 and putting around the 4 corners and still no success to avoid the echo.  On the floor, I have put on the carpet.  The missing part is on the ceiling.  Somehow I got difficulty to put something on the plaster ceiling, first the ceiling cannot withstand heave weight item and second got ceiling fan at the middle 

regarding adhesive.......there's this thing from 3M called Command strips...its double sided tape...there's weight rating on the thing...so you can estimate how much of adhesive to use.....best thing is that it is removable from wall without stripping the paint off....surefire can get approval from HM.

DIY sound trap.  I'm using Roxul MPS400 (density 80kg/m3).  The woods/plywoods cost more than the Roxul itself 

Just came back from Homedec Penang. Saw some acoustic foam which is quite cheap. RM70 per pack with 4 pcs of 60x60 cm foam. See website below : http://www.m-pe.com/En_02_products_M_Sorb.html
