I went to see what Speedysteve7 does. I did not read the text. I just glanced at the text and seen the mentioning of multisampling with digital amps, mentioning of digital crossover. All of it and the most important the rock-end-roll crap the he plays in that room makes all his playback efforts no different than to applying make up to a corpse in order to look it more alive. Still, I decided to mention the Speedysteve7 progress as still there is something in what he does educational for others:

He did not BS himself like other heroes do but measure the responses of individual channels and groups of the channels. I did not look close what  and how he did it, I am sure that he will not interpret the results in the way I would agree but the fact the he was at least trying to do it is a good sign.  The only playback that do not require any measurements are playback with Goto drivers as the green color of the Goto magnets self-equalize the waves in a room…

 It looks like he got the clue presumably from my post above, cut his MF horn and placed the tweeter in correct location. This is very right move. For this, what I call Macondo configuration, this is the ONLY location where tweeter might sit. By cutting the MF horn he got a bit more upper knee extension from MF and less beaming. He for sure need to move the MF horn a good 1 feet down and to get rid of that horizontal shelf in front of the MF horn, In fact the hole horns assembly needs to be moved 3 feet forward as the tweeter picks up the side wall of the tapped horn but this is a whole another story… The glossy pictures on the location of the first reflection I guess work well with class T amps…
