What Horn loaded speaker/ speaker system for $10k'ish and under

For me, horns are the way to go. I have owned all the Klipsch Heritage models ( not all of the different series ), and I feel the Lascala, which I own, offers the best bang for the buck. Of course, they need some attention with vibration and resonance control ( and the correct crossover specific to the listener ), and if you need the extension of the lowest 1/2 octave, a pair or more of subs can do the trick ( not all subs are fast or agile enough ). For me, the LSs do more right than wrong, work great in my room, allow me to listen near field, and sounds great with a number of many different amplifiers. By themselves, the bass reproduction and " tunefulness ", is awesome, and they are, imo, very coherent. I get quite a lot of musical satisfaction from them. I have heard others, with conventional woofer set ups, such as the 4367, lower priced Volti's, Altec 19, Avantgarde, etc. and often hear a disconnect between the bass, and the horns. Keep in mind, this is based on my listening, my room, and what pleases me. YMMV. It comes down to what characteristics, both good, and maybe not so good, you can live with. Every speaker / room is a compromise in some way. 58 years in this hobby ( I am 69 ) has taught me this. Enjoy ! MrD.

I agree with mrdecibel. One should be aware of the large design differences between horn models and the comprises they entail. Some of those horn loaded woofer designs sound very different from hybrids and have different setup requirements. I have owned the 4367.  It has lower efficiency, requires a very high-watt amplifier and has a better step response. It is not full range, like a D9 but LF extension satisfaction will largely depend on your taste and your room. When given power the woofer is outstanding, though.  

If you liked LaScalas but want something more refined, consider the LS II or the AL5. Much better than vintage LS.

While we're on the subject of LaScalas....I own a pair of them powered by the Raven Blackhawk tube amp. Recently I finally decided to try the Bybee Quantum Clarifiers. They cost $200 for the pair. They conveniently magnetically attach effortlessly to the rear protruding mid horn magnets. (I love non-invasive tweaks that don't cost too much) Fantastic improvements beyond words. But I'll attempt to voice some impressions...clearer for sure, instruments are less hazy, the sound stage isn't as tunneled but pleasantly naturally spaced out. Vinyl playback has gained an air and sharpness which stuns me. LaScalas apparently can benefit immensely from these small square "magic" attachments! Revolutionary. I'm just sorry I'm so late to the Bybee creations!

My older 1989 LaScala's were not stock by any means, all the drivers were from Crites, Crites 4500 crossover as well, i also damped the horns with dynamat and the cabinet was extensively damped as well. so they did not sound anywhere near what the originals sounded like. They were really nice and I regret selling them but I I hate black speakers and they were black, and looked like black holes.  I was going to buy the new ones in a wood finish but thought I'd try some Spendor D9.2's after a listen at my dealer along side the Klipsch's. Regrettably the Spendor's did not work in my room, reason I'm back on the speaker hunt.
