Here are the things I did:
- Speakers usually benefit from the golden triangle rule which says to make an equilateral triangle between you and your speakers. I found that the 601s didn't work this way. I had to space them considerably further apart than the distance I sat away from them. In my set-up, they were 10 feet apart and I was 6 feet away. This works out to be a ratio of 1.67:1 instead of the golden 1:1.
- I moved the backs of the enclosures 2 feet away from the wall I faced. This made a huuuuuuge improvement in soundstage depth.
- Toed them in 30 degrees from the normal. This focused the centre image which otherwise was too big.
- Kept them equidistant from sidewalls. This tremendously improved the imaging.
- Crossed them over at 100Hz.
- Turned up the treble half-way from 0.
