How far do you sit from your speakers

Yes, your triangle is much longer than most I have seen, in most systems anyway. (Of course it also appears that you have a bigger room than most people, in order to have a 17 foot dimension to each speaker.) Care to give your room dimensions and how the speakers fit within them?

My speakers are about 9 feet apart, and I sit about 11 feet from each speaker, (or about 10 feet to the plane produced by the face of each speaker). My speakers are about 4.5 feet into the room, and centered on the long wall of my 24' x 16' room.

My room measures 13' wide by 23' long with a Staircase in the left corner and an alcove under the stairs in the right. The spaces behind allow my speakers to be 30" + from the back wall.

Because of traffic patterns my speakers are as far into each corner as possible. A much less then ideal situation.

I am also saddled with a huge ET cabinet between them. Our son made it for his mom and it appears that I am stuck with it forever!

When I was in a larger room , I had the speakers 11ft. apart and sat 11ft. from their face . An equal lateral triangle that gave me unbelievable soundstaging . The speakers were 3ft. from the side walls and about 6ft. from the wall behind them .

Now I am in a small 10ft. X 10ft. room with the speakers in a 6ft. equal lateral triangle set up on the diagonal .
I don't have anywhere near the same soundstage . Square rooms are tough !

Happy tunes .

I like the near field monitor arrangement. In all of my rooms I have suppressed the primary reflections by sitting close. I am 10.5 feet from the speakers and the speakers 9 feet apart, which is a ratio of .86 This has worked well for me in all the setups. I am in a large room so I don't have to worry about reflections off the back wall, the front wall is dampened and the speakers are 3 feet from the side wall with diffraction there. It is very speaker dependent. The wider the angle of dispersion of the tweeters and midranges, the wider you can move your speakers. I also toe in my speakers a bit. This is after several years of moving a little this way and that, and eventually ending up here. part of the fun, I guess.
