Re: Room Treatment Options?

Yup - that can be a real test.

If you can't do any side to side movement of the seating and setup, then you may end up having these anomolies. In that case, and assuming it is width related, you might need to experiment with treating walls directly beside the listening position.

With 11' of width to work with and two couches I loose all seating flexibility. It also dosn't give me much to work with for the mains because, if I understand correctly, I should maintain a minimum 8' distance between speakers and keep them 1.5' from the side walls.

However, I thought one of the advantages of using absorbtion/diffusion was to broaden the sonic 'sweet spot' beyond the primary seating position? Unfortunately, I have such a difficult room to work with, I may never be able to achieve that.

You lost me with this. Which anomalies do you suspect are width related? The 52Hz peak should be length related. Actually, it shows up as both a 56Hz axial and tangential mode on the room calculator.

Hmm... I just measured the room width including the dining area and it is... 19'. Looking at my room diagram, another way to view this space is as a 20' square with a few extra walls in it. Maybe that explains why I have such a pronounced peak in the 52/56Hz area? Sigh...

On treating width related next to the seating position:

How do I do this in an asymetrical space? The right side of the couch is 10' from the diningroom wall, the left side, 2' from the livingroom sidewall.

The rear wall:

I remember reading several times in the past that you don't want rear wall reflections at all(low, mid or high frequency). I have been looking at my setup, and I can actually treat most of this wall. I do not have anything in the lower shelf of the aquarium stand so I could actually put treatments in that space as well. I can easily put a panel 3' high the width of the stand and 2" deep in front of the stand and then put additional treatment behind and under the stand as needed.

Re: Room Treatment Options?

Hey, maybe I could build a wall between the dining and living room area. I'm sure the landlord wouldn't mind.

Re: Room Treatment Options?

Well, that would certainly lean toward explaining it. If the REAL space is basically square, then they'll be very very pronounced. In the calculator, which tangential is it?

What I meant with the treatments was panels directly beside the seating on the one wall that you can treat.

If it's length and width, combine that with a thick set of panels on the rear wall and you've dealt with both.
