I built a set of DIY Sound Group Titan 615LX two years ago, and it is uncanny how expansive a sound stage they throw yet still have pinpoint accuracy in placement. I've owned various other speakers the past 25 years including Meridian DSP 5200/5000/5500, Ruark, KEF, B&W, Mission and Boston Acoustics, and never experienced that kind of imaging. Maybe it's the horns, or that only now I have a fully treated room (acoustic design by Shawn Byrne), or something else about them, I don't know. I now feel done, completely content, with speakers.
