welcum welcum to new users

very interested to have this too..

did u diy? how much did this cost and where to source for materials, esp the foam?

er... wat are acoustics panel for? can advice?

The Missing Element:
The missing element in most home theaters is proper acoustical treatment. Why is the room so important? The reason is that sound must eventually travel the acoustic path from the loudspeakers to our ears. The sound that we hear in a
room is a combination of the direct sound from the speakers and the indirect reflections from the room surfaces and room contents. Indirect reflections can cause acoustic distortion, so that you end up listening to the room and not the intended soundtrack. Hence, reflection control is a central problem in creating rooms that allow a suspension of disbelief.

Anyone interested in Spyder2 + Calman v3 (license copy)? I'm thinking to upgrade to Optic Pro Spectrometer. I'm selling for RM 700. Calman is easy to use with their step to step contrast/brightness setup, greyscale, primary and secondary color adjustment.

yes, i diy'ed the 4 panels myself using 1"x2"x8' timber, 1/8" plywood backing the frame, just nail up the frame with the plywood back.

fill up the frame with rockwool up to 3" thick - i made two 3" thick panels and two 2" thick panels

btw, rockwool is cool


then wrap up the whole panel with 5mm PU foam using stapler gun.


final result


approx cost per panel is RM80 each. timber from timber yard wherever you can find them, rockwool and foam from aircon installer

I'm using these panels for first reflections.

next project is to make bass traps for the 4 corners. then tackle front wall and ceiling.

Yours is cheaper than me , the different is my rockwool is above the frame then wrapped with fabric . also back is hollow and doesnt cover with plywood.

ycs, didnt know taht you are so good in DIY. I am a lousy fella in this. Thought of making my own for both acoustic panel and bass trap. But, worried that the end result is a mess.

lohlm56, I am interested to know abt it too. Care to share with us all here?

yes, i'm also looking to make diffusor, looked at some plans but have to see what i can get from timber shop, also i cannot make too big coz back wall got window. thinking of installing some curved plywood strips to diffuse sound.

btw, have you got bass traps too? mind to share your plan. do you also install on ceiling? how?

I am planning to use mdf and buy a electric saw for cutting pcs , key point is how to fix them together by either screw with screws or glue .

Guys, make sure the back is hollow. And float your panel from the wall with at least 2" gap. The reason for this design is to double the effectiveness of your panel. The sound will travel pass the panel in first pass, reflect back by the wall (reduce sound wave) and go through the panel for 2nd pass. I found a lot of reference from internet. Will take the picture of my panel if anyone is interested on how to float the panel. I just screw in 4 x 2" aluminium tube with rubber feet at 4 corners and hang it on the wall like picture frame. This will allow you to arrange the panel in the most flexible way. If you feel it is over absorb, just shift or reduce the panel to experiment.

Bass trap at 4 corner is a must. The bass is control and deep.

Diffusor actually can get it quite cheap from hiwaylaser. Around RM 150 per piece.

my panells are floated on the frame and back is hollow and consider as bass trap , can you put picures of aluminium tube with rubber feets at 4 corners , i am thinking of screw 4 pcs of solid block of woods and hang it.
