next a test cd with individual tones. Note: I scanned several Stereophile Test CD’s, others, none of them have the full range of frequencies this test disc has (29).

you will know how flat of a frequency response your speakers are producing, IN That Space, AT that location.
Next, try new positioning and different toe-in, measure the differences.
Amazing Bytes is hard to find, and expensive, I can find a used copy if interested.
