Hello All,
Thank you for your comments farfetched. My current listening position is a bit shy of 3 feet from the corner, so I agree that is a sweet spot for this arrangement.
I have tried a more "near field" listening position, and have taken some measurements as shown in the figure. However, in my room I get a very steep roll off in bass response below 100 Hz, and a lot of room mode ups and downs. By putting the listening position back in the corner, I recover a lot of that lost bass energy, even to the point where I had to apply some electronic equalization as described earlier.
I will check with some of my friends for the Jefferson Airplane disk.
Cheers,
Chuck

I am assuming that you are moving the seat parallel to the back wall at these alternative seating positions, do you adjust the speaker toe in and location at all for these?
You obviously have very strong nodes at 40 hz (bump) and 70hz (cancellation) - and an overall lack of pressurization at the 6-9 ft positions along the back wall, have you tried sitting further out into the room?
Hello All,
Thanks for your comments Satie.
Sorry for the confusion, I moved the microphone (listening position) diagonally out into the room, in a North-North-West direction referencing back to my original room layout diagram. I collected this data many months ago when I was just starting to try to get a feel for what I could and could not do in this room. I positioned the microphone by eye at a midpoint between the speakers, but actually measuring the distance back to the corner. The speakers were positioned within a few inches as shown in the diagram. From the data presented in the last post, it looks like my eye-ball distance estimate for the 6 foot location was not so good. At that time I was not thinking about the subtly of toe-in, so I am not sure what that might have been.
Cheers,
Chuck
