toe-in will impact any speaker response, also dynamics and sound pressure that you receive, and it all a balance based on your room size and how far you sit from the speakers. You have to work with what you have and that the bottom line and make the best of it. Once my speakers are fully burned in, then I start playing with the distance between the speakers and toe-in and distance from the front wall. With my Quads a 1/4" change in toes-in would change the whole field in the radiating area and dynamics, once lock-in you heard it with ease, it was like looking through a clear window into the recording with a speed and dynamics, toe them out more or in more from that point you heard the magic left. Spatial is the same in my ways but imaging wise you have to play with the toe-in along with the dynamics and getting the balance from the highs to the lows. For bass, I use a recording on the Chesky system check demo disc, (it is a standup bass Track 27), it can sound all detail and less weight and body or lots of body and less detail, depending on my toe-in and also distance the speakers are a part in a given room, buy rule if they sound lean move each speaker a few inches closer towards each other, it is all a balance, but the steps you have to do to learn how a given speaker can sound in YOUR room, not my room as you play with them you start to learn what effect the changes your speaker goes through in your room, and like education yourself you will learn how your current speakers sound it best in your audio room. I enjoy that part of buying a new speaker, but at first, it is frustrating because you may have had your last speaker set up just right and sounding good, and now you have to live with so, so sound to you learn what is needed to get your speaker sounding good again. I always start when my last speaker was, and due to my Quads being dipole, and the Saphire M3's being that way also, with the mid-woofers and woofer, I knew they have to be out from the front wall, though I played with that at first just to learn the impact of closer to the front wall and than moving forward 2" at a time same for distance apart, then lastly toe-in, 1/4" at a time till it locks in image-wise (using a mono recording), then I live with it for a while then one the day I get up and toe-in them in another 1/4" and see the effect, if it is not as good, then I can easily go back and I know I've locked the speaker into my room.
