3D imaging

Actually crossovers do matter, steep slopes screw up phase and that means poor impulse response all inside the 3-5 ms “ rule “
actually electronics do matter, negative feedback also screws up time and phase and can lead to TIM, wonder what the T stands for ?
time alignment of the drivers matter
pistonic drivers matter, an out of phase cone is destroying the image information as well as screwing up frequency response
low reflection cabinets, treatment inside the cabinet AND a low reflection driver magnet are available in certain products
managing the grill edge can reduce the baffle step effect and so can managing driver directivity- not all drivers radiate off axis at same level, so reflections can be down in amplitude reducing reflections
cabinets matter
:-)
oh and how a driver stores and releases energy can be seen in the impulse and waterfall plots, pay particular attention to those mid ranges wired out of phase, panels with edge clamp issues, speakers that start negative, waterfalls that never end....
vast is a relative thing, I am just a student...

And unless you are listening in the near field, the room matters a lot.... a mix of absorption and diffraction are key ....

I just put the Chartwells back in the system. They are 6'9" apart. My seating position puts me 7' from each speaker.(triangle) I guess that puts me in the near field camp? I'm ok with taking some of the room out of the equation.

millercarbon and tomic601, Thanks for taking the time in answering theses questions and help me get a better grasp on what my ears(brain) hear. Am I far off the track in stating that audio or should I say"better" audio is partly based on manipulating the brain? 

With respect to the Chartwells my guess is that you will get a better soundstage by moving the speakers closer together, making them 5 feet apart, even less perhaps, with no toe-in. Most speakers are set too far apart. 

I do have these with no toe in,so let's give it a whirl moving them closer together. I'll report back with my results.
