Acoustics for a Nice Sounding Media Room.

[Baljinder]

After Building Subs i.e 21 Inch Full marties, my next achivement is Acoustics. I have gone through lot of rooms throughout the globe but I have found lot of problems in designs. To correct all i have built my media room measuring 11x14 Feet with proper corner traps. I am midway in building room but will update time to time. A glimpse of the room is attached herewith. Open for suggestions and Questions. I am building four 18 Inch Mini Marties In this room IN Doube Bass Array Configration with Arcam AV 41 Processor.

Lovely...you seem to be going fully monty with the room. There seems to be adequate damping for the 4 monster subs you will be stuffing in that space

I can see that this is a serious room treatment exercise with a lot of thought, and commitment put into it. Highly appreciate that

But since your goodselves have asked for feedback on a public forum, And more importantly, since Iam bored at the moment, below is my 2 cents

Unless the room is for a pure multichannel system, where we want minimal reflections. For a 2 channel system, we need some amount of reflection. So I think the outer shell above the damping material, at first reflection points might be better off being reflective. Just my 2 cents.

And from my own experiments, I feel there is a delicate balance between a live and dead room. I had over damped the room without even knowing it. REW wont tell us that, no way. It took almost one year of listening to realize that I'd gone overboard. Luckily, my first reflection treatments with absorbers were never permanently fixed. So could retrace my steps to correct the balance again. So apart from the bass treatment, which we can call as the base layer, the top layers of absorption or diffusion or reflection especially at first reflection points, are better off being flexible, until you are really happy with the entire balance of what all these treatments are giving. Which will only be realized over long term listening.

But the above said, it is your room and your ears in the end. And opinions of others, including me dont matter . There are folks happy with deliberately over damped rooms. So whatever floats your boat

Will watch your room build with a lot of interest. So please do post "LOTS" of pics along the way. All the best

I agree with you sir. Thanks for writing this much. A lively room is what is more important than Dampening the room. Next step is to cover the Acoustics and i will show the real work like Anthony Grimani dictates. I agree with you, 99% rooms in our audio industry are dead rooms with over Acoustics. I did my homework first before starting Acoustics. Will share my build as it proceeds. I am professionally building subs for my clients at the moment and the present order is GSG (BTS) Behind the screen subs measuring 36x40x17 tunned to 19Hz with Lavoce SAN 214.50 to he delivered at chandigarh. And next week billing of Arcam AV 41 Processor. Then i will cover the important reflections for lively sound. Thanks again for support from the whole community. I assure you , with the passion I am having, you wont find 2nd Indian with this quality and perfection work. I will share the REW Graps of the room with 4 subs from 10Hz to 40000Khz which will show the actual work. For the forum my 2 cents to learn some actual Acoutics just Google (STC 63) it will take all the knowledgble persons to another level. STC is sound transfer coefficient....

Thanks a ton for sharing the above....off to read about STC now

And will stay glued to this thread for more build pics as it progresses. Just curious about the subs, are the mentioned dimensions in cms or inches

Subs are in inches with a total volume of 10Ft³ tunned to 19 Hz in WinISD.A sample pic from my fellow friend in USA.Also a bag of rockwool is 2500 in 48KG so reference price as its mostly overpriced throughout the country specially Aural Exchange...
