Yes 4-way digital active is the way to go. I did it over 10 years ago with Legend's Tikandi Grande loudspeaker that has many similarities with the Linn 360 though I used a triangular front baffle rather than large radii to minimise edge effectsNice to have you on this forum - I loved the sound of active Keltiks and also had active Kabers. I follow your speaker constructions at Legend acoustics with big interest. It seems that an active 4 way speaker is the way to go, without big compromises ?
