What does one purchase after owning horns?

"IMO the fact that horn-loaded drivers don't have to move much to make a lot of sound helps keep their distortion down."

Mass and inertia are certainly big considerations when designing any high performance speaker, no doubt.

The bending wave theory of sound propagation associated with Walsh style drivers is another design approach that I think solves much of the problem in a very unique and innovative manner.

Of course the radiation pattern of a Walsh driver is at the exact opposite end of the spectrum from horns or waveguides.

Its cool that there are so many different ways to tackle the same problem!

Paulfolbrect, I was referring to the width/length of the horn/throat. I admit that the construction can be better. When you had the Khorns/Lascalas did you do any damping to the mid horn (and cabinets). Every pair I was ever involved with, after damping, eliminated most of what you speak of. As a sidebar : Speaking of damping, I find most tubes have colorations and distortions until you dampen them. But please lets leave this topic to another thread. Regards...

Atmasphere,
am I right in saying that due to this impedance curve on the trio they designed the CDC? I was under the impression this made it tube friendly

Magico Q3,Q5 Much better.

Chadeffect, it does appear the newer Trio has a higher impedance. Their website does not have a lot of technical data, but it seems pretty sure that 3 of the 4 passive crossover components must be caps. If a choke is added to the bass horn, the overall impedance would not be such a hard load for tube amps as the earlier Trios. Overall it would appear that the speaker is nominally an 8 ohm load.
