Hi, This is my first post in this forum. I moved to a new apartment and I need some help in positioning the speaker and in doing some acoustic treatment. I just moved to a new apartment and I am attaching the plan view of my apartment and living room. I have not even positioned the speaker yet so I am not sure how it will sound. As of now I have identified this position please see the attachment, I am not sure it is a good option or not. One issue is I am not able to get symmetry , it is open on right side while I have a wall on left side. Is it important to place couch so that it forms an equilateral triangle, I mean distance between speaker and listening position? If I maintain an equilateral triangle the seating position may be at center of room, in general I have heard that seating position at center of room is not good due to wave cancellation or null. Can we go with rule of 1/3 rd or 1/5th? Please let me know your suggestions. Thanks in advance. Attachments:

Hi all, I am not sure if you guys are clear with just plan view of apartment and room. Please see the pictures of room. One side it is open and other side I have wall and hence symmetry between left and right speakers is an issue. I can position my listening position at 38% from rear wall. I can place absorption panels at reflection points. Please let me know your inputs. Thanks

Hey lal. Congrats on your move. Ultimately, your room is pretty much a square with a kitchen in it. I'd say pick a few comfortable spots, measure them with acoustic software and pick the best one. For what it's worth, I'm lucky in that my girlfriend who picks our apartments supports my hobby. To that end, we select places which are likely to give the best acoustic response. You've already moved but I advise anyone else, or you in the future, to keep room layout in mind before making a final decision.
The last thing I can think of is to use the larger bedroom. While the volume is less, there you won't be encumbered by obstacles. You can always treat the beetles out of it.
Thanks.

Thanks Hexspa for your reply. Before moving I felt this is a good room with lot of space compared to previous apartment. You are correct it is a square room with kitchen in it. I should have planned it well.
Now that I have moved need to be here for one year. Do you have any suggestion for speaker positioning or on acoustics treatment?

Hi Ial, Welcome to the forum. Thanks for the floor plan and the photos. It sounds like you have studied Ethan's docs so you're off to a good start. As you know the dining room area creates asymmetry so you'll have to work with it. Reflection absorbers on the left wall should help. A ceiling cloud will also help with reflections off the ceiling. Measurements with REW along with listening tests will help you find the best speaker position and seating position but 38% is a good start. You didn't mention bass trapping so I don't know just how much you want to treat your room but again, measurements may either indicate you're OK without or encourage you to delve in further.
Maybe other members will have better suggestions.
Cheers, Rock

Hi Rock,
Thanks for your reply. I can add few bass traps and panels at left wall and may be on rear wall if needed. I have Dirac on my AVR and but I am not sure how I can use the data from Dirac. I will explore. Other option is trying REW. Main concern is how to tackle the asymmetry on the right side. If right side is open ( to dining area) is it a big issue? I understand there will be bass reinforcement for the left speaker.
Regarding listening position I have some flexibility, I will start with 38% and then based on listening or measurement I will arrive at the best position. Regarding speaker placement any recommendations for distance from side and front wall? I know it is hard to suggest because each room is different.
Any option to cover the tri corner in the ceiling , is there any bass trap which can be put at the tri corner other than using a bass trap from top to bottom?
Thanks Lal

Do you have any suggestion for speaker positioning or on acoustics treatment? To be fair, I did do just that. I've gone back and highlighted that info in bold. Taking a second look at your room, why not flip your recliner around and put your speakers against the wall by the hall? Previously I had a room with a similar setup and got a decent result. Either that or sit center to your sliding doors and face them.

Thanks for your time and suggestion. Your suggestion is to shift the speaker to the opposite wall in living room and recliner in front of sliding door. I thought about this before but one practical issue is that speaker will be on the passage and in case people come for maintenance then they may not care much for speakers. Still I can try to do that. Do you see any real advantage in doing this? Sliding glass door is preferred at the front or rear wall? Thanks Lal

I'm looking for symmetry and listening position. Symmetry matters most from your ears forward. You'll probably get the best symmetry, and acoustic treatment placement options, by facing the sliding doors.

You are correct, it is slightly better compared to present position but again other side also it is not perfectly symmetric. But I am not sure if I can with the direction suggested.

No problem, just follow the flow chart back to my first post and pick comfortable spots, measure them, and select the best.
By all means, if you're looking for some information and not getting it then please specify. Again, you undoubtedly have obstacles. The absolute best thing you can do is what I'm telling you. Creating an acoustic simulation of a complex space such as yours, as far as I know, is beyond the abilities of personal computers. Besides, it's a waste of time. Just start recording sweeps.
Thanks.

Among other non-acoustic issues, I see a dining table in the "dining room" in one of the photos. My reaction is that this would preclude the listening position in front and center of the sliding doors... maybe not if it can be moved to another area. We need input from the OP (and other decision making occupants).
Reversing the room and facing the "back wall" is another option Hexspa mentioned and that is certainly another way to gain symmetry. The issue there might be traffic but again, that's up to the OP (and other occupants).
But I agree, start sweeping and get some baselines.

Thanks Hespa and rock for your time and suggestions. As mentioned earlier the issue with flipping is traffic and even if I place it on the back wall (opposite to sliding door) still it is not perfectly symmetric but it is better than the position I thought of placing. Let me see if that is possible or not.
Room measurement you guys mentioned is using REW? Can you please give some more details?
Thanks Lal

I really regret not giving too much attention to room layout while selecting the apartment. Due to some reason while selecting this apartment I felt living room is big and will improve the sound. Sad part is I just upgraded my speaker and I have a new speakers and now both room and speakers are new. Not able to make out.
