Klipsch La Scala 2018 or the Triangle Cello?

Wrong Klipsch. Go with the Cornwall and add two subwoofers like JL Audio F113's. Cross at 100 Hz.

The LaScala's problem like the K horn is that the woofer is some five feet behind the midrange horn creating a timing problem. The Cornwall does not have this problem.

Five feet? Are you talking about the length of the bass horn? Surely you don't mean the woofer is 5 ft. behind the midrange horn?

"Perhaps you haven't heard the current generation of Klipsch speakers. They do the imaging trickery and finesse better than older klipsch offerings. The new Cornwall IV is extremely hard to beat in it's price range."   Oz

I have not heard the new Heresy IV, Cornwall, or LaScala AL5. I have owned the RF-25, a pair of factory custom Heresy IIIs, and have spent some time with the last gen LaScalas. The Triangles and the Klipsch have completely difference sound characteristics. The Triangles being very electrostatic like with a deep sound stage and a very transparent presentation. The LaScalas are very dynamic and efficient but they trade frequency response for efficiency and have the problems of horn systems (resonaces, etc). I liked the LaScalas but I would grow tired of the sound very quickly. Perhaps you are not familiar with Triangle speakers, LOL.     

What will you be using for amplification?

For a short time I lived with my 35 watt Marantz 8B rockin' a room mates La Scala's decades ago and I currently use Triangle Comet's in my home theater.
Regardless of my fond history with horns any attempt at a meaningful memory based comparison on my part would be as far out as my UFO sighting two hours into some Blue Wedge.

Presentation preferences aside the Cello's are said to have a 2.5 ohm point.
My Comet's driven by my Elite receiver's 125 watt switching amps can be surprising even with broadcast sourced audio. Driven by the more powerful Carver Tube mono's was the no brainer to purchase five more for the HT.

I remember that UFO sighting like it was last night and I enjoy the Comet's. Astronomical kook?
