@wrm57 assume I’m ignorant of what you’re saying, even when 20 years experience in this hobby. My line magnetic 518 has taps for four, eight, and 16 ohms. Would that make a difference with those triangles?
I mean simply that a 102 db horn-loaded speaker with a relatively flat load of 8 ohms is going to sound different than a less-efficient speaker that has a deep impedance dip and is made with cones and domes, especially on a lowish-powered tube amp. Not necessarily worse but different, especially in dynamics, which are a primary horn strength. These are different categories of speaker, each with its own virtues to offer. The various taps on your LM will certainly help to match it to the Triangles. They might well sound fantastic together, better than the CWs in some regards. I am by no means suggesting they won’t. But I’d wager the listening experience would be quite a bit different. I, myself, will be experimenting with the Klipsch specifically because I’m looking for a different sound than mid-efficiency cones and domes, which is what I already have in my main system, not as a replacement but another flavor. So it all depends on what you’re after.
