Is an eight sided oval room acoustically correct?

Interesting question. My initial reaction is that this shape might work well, since I have heard audio systems in dome homes (circular in structure) that sounded very good. There is still a chance you could some standing waves, however, since there will be four pairs of parallel wall surfaces.

This sounds like a question for Sean and/or Rives Audio...

If the cuts are minimum it's a good idea. It will relieve the corner pressure. However, if they get too large it begines to create some pretty interesting interactions that are not easy to describe, but suffice to say that more than about 15% of the length of wall cut as you propose and you may encounter some problems. As to the "dome", well, I don't like to disagree, but about the only worse scenario would be a round room. The dome will focus energy in one place. If you go to our listening room you can see what a bay window can do to the sound field. A dome compounds the problem. It can create a "neat" effect, but is not advised for a dedicated listening space.

Rives, you have a great deal of useful information on youre site.

Looking it over brings up some questions that I am giong to try and solve. I have a bay window directly behind my speakers and a sliding glass door to the left. I know that these both contribute some problems to the sound. The bay is not easly coversed by drapes or blinds as it is home to my wifes huge philodendron. This is the only place in the house that it fits and is very happy there. I am wondering if you have any experience with Murigo Audio Labs window tuning dots. I know that it is not the ideal situation or solution, but the room does need to serve as living space to some degree. I am fortrunate enough to be able to set the room up for the Hi Fi and nothing else other than the computer and as an area to relax and read.

Another product that I am curious about are the Golden Sound Company's Acoustic Discs. Any thoughts on these?

Maxgain: I do have experience with these types of products. What they do is reduce the resonance in the glass. This may be a problem for you (it depends on the glass insert), but it's not the problem we discuss regarding bay windows on our website. These materials will do nothing for "focus effect" problem that bay windows have.
