Horn speakers with Imaging?

My previous Klipsch Forte 3's imaged very well. The Cornwall 4's that replace them were not imaging quite as well until I began tweaking the audio equipment driving them with brass spike and cup style supports. You might notice that the thinner speakers tend to image better than wider speakers right out of the box.

About 6 months ago I set up some floor-attached angle jigs perfectly aligned together with the wall behind them. Angle matching between the speakers is determined by measuring the distance between the leading speaker edges and the wall behind. Speakers can now be in perfect alignment as to distance from wall and angle. This makes fiddling with imaging much easier. With Cornwalls very slight adjustments can make big differences in imaging, tone, treble response, bass response, etc..
