panel placement help needed.

I hope you mean 4in and not 4mm or even 40mm. 4" minimum for RFZ.

I've looked at your drawing. I'd say fill that 5' enclave with 24" fluffy insulation with an air gap behind. You can then face it, set your LP 38% from there and still have almost 10ft behind you, some symmetry plus lots of bonus bass trapping.

I'd wait for a second opinion though before spending money. Typically you'd want to put that much insulation behind you. However, you have a kitchen on the other end plus a door.

It would be better if you could flip the orientation and remove the kitchen, replacing it with insulation but I doubt that's going to happen.

Hey prash. I downloaded your image and flipped it around a bit to try and get a better perspective.

BTW, when I said "pocket" I meant where your entertainment system currently is located. From here on out, that section will be called "the pocket".

So I think you can set up your studio where the TV is. Alternatively you can face the right wall, centered 14.74' (or maybe off a few inches). This will give you symmetry ahead of you between your head and speakers plus a nice window out of which you can gaze - the window will not affect your acoustics as much there either.  Additionally, if you're going to continue to use a surround system, the window-facing configuration will allow for better positioning of your satellites.  

You will not have to treat your left and right RFZ points since they'll be further than 10' away (walls further than 10' are not early reflection points. You will simply have to place movable panels or soffits behind you - no problem. This will also give you more flexibility when treating your vertical corners.  You'll just need to hang a cloud array if your ceiling is less than 10'.  Remember that surround satellites get clouds too. 

If you haven't, please consider downloading my free ebook at hexspa.com/listening-room-ebook It's a condensed version of whatever I've learned up until I'd written it.  It's not endorsed by anyone per se but I've gotten verifiable results several times with that information.  

The last thing I'll mention is that, truly, the only way to find the ideal location for your LP et al. is to measure with a linear omni condenser and Room EQ Wizard-type software.  This will require trial and error but will give you hard evidence as opposed to the possibly maybes you can get from anyone without that data.  Of course, I wouldn't be surprised if someone like Ethan has assisted with a similar space and could make an accurate prediction.  Even still some things might pop up that graphs can help you diagnose.   

Additionally - typically the advice is to fire lengthwise down a room.  Again, this is where REW etc. will help.  The thing is with setting up a room is that there are many factors and steps to consider.  Few people score 10/10 - I don't - and that's ok.  The name of the game is doing the best with what you got.  You get bonus points for continuing to experiment, measure and refine.  

Thanks,

1. Can i place 4ft x 2ft x 4inch (2pcs)stacked one panel top of the other to get 8ft tall, on the corner (45 deg)for the whole height of the room?
Or should i use one panel of 8inch and use tri corner?

Thank you hexspa

I think pics are in order.

Ethan requested that they remain under 100KB so you might need to shrink them.

I think to find your best listening position you should do a REW measurement rather than rely [edit:exclusively] on your ears.

It's no different from any other art where senses and tools must come together to reach the best result.

Straight lines are not always the most desirable.  

The right colors might not work.  

38% might not be the best LP.  

Congrats on making the leap.

ive done it at last. attaching some pictures, pls suggest any corrections.
