Who positions their speakers straight ahead (zero tow in) and why.

As others have noted, every experience is different. Here is mine for what it is worth:

- room is semi anechoic: rock wool covers the walls (6”) and ceiling (14”), with fire resistant burlap covering that

- rugs cover most of the floor

- room has a gable roof, 8ft at the peak, 3 ft at the walls, with a large gable opening to the right.

- the distance behind, to the right and to the left of the speakers is - roughly - equal to the distance between the speakers

- the speakers are not toed in

- the speakers are Altec Lansing 604Cs in homemade cabinets that were made to Altec specifications. They are co-axial.

- I sit about 10 feet in front of the speakers.

This gives me a wide and deep soundstage with solid imagery. On most records, the speakers disappear. In many records, the sound is holographically surround.

My room is approximately 14 ft x 22 ft.

The roof is gable: 8 ft at the center, 3 fact the “walls”. The system is aligned parallel to the gable axis.

Is that a “small” or “moderate” room?

I use NO toe in. I had been using toe in for months, but the center was mushy and unstable, the sound bright, the stage shallow. I removed the toe in, and @g2the2nd  the center stage was far more solid, the stage wide and near surround.
