I am interested to find out more information about how DEQX will help solve my issues with getting better soundstage, imaging and depth with the Edgarhorn Titans.
Marc, finally I have something to say. I also have the Edgarhorn speakers and use a 2A3 SET.  I have tried the DEQ in the past, and some people love this. I did not. I think it very much depends on what you want. The DEQ gave a very balanced and neutral frequency balance to the music, but for me it sucked out the soul of the music. In fact even without any so-called EQ, just having the DEQ in the system caused the sound to deteriorate. For me it is all about the connection to the Living Presence of the Sound, so it was not an acceptable solution. 

Now other people have used the DEQ and Edgarhorns for their satisfaction. They do get a very nice soundstage and tonal balance this way, even though to me the music becomes uninvolving and energy-sucking. If you are interested mostly in soundstage and microdetails, yes then this may be a good option for you. But that is not my interest, and with DEQX, the prana has left the prasad, so to speak. I could never imagine giving up the benefits of horn speakers for Maggies, as much as I loved them 20 years ago, but if you enjoy them then sell the horns and go with that because all speakers have different weaknesses and strengths. Audio is a fascinating exercise in design compromise. Don't waste your time thinking that you can make a speaker do something it is not good at with little tweaks; just get a different speaker.

That said, I bet you have your speakers set up in a traditional position in your room. The way you describe the narrow listening zone, etc. is a giveaway. Well, there is another sweet spot and how to find it is described on this website in detail. This other sweet spot is not where you expect it to be and you will spend a good deal of time with toe in and toe out, and moving the speakers just a tiny few mm, until it will snap into focus. Also, you must work on the midrange/tweeter, which can be moved separately. For me, I had to adjust them slightly asymmetrically. Now, it is all worth it and I have tape marks on the floor to mark the spots exactly. The soundstage opens up and I can move quite freely and still enjoy excellent three dimensionality. Again the DPOLS is essential for the appreciation of the horn speaker but you will have to experiment to find it.
