Speakers similar to Avantgarde horn

They sound like that because they are front loaded horns....conventional loudspeakers are going to sound like, well, conventional speakers. Are Oris 200's a little smaller?
Sorry, no free lunch.

Maybe the Quad ESL 988 is what would do for me. I still need to make sure my room is big enough for them.

HUH?! The Quad ESL 988 is a great speaker for sure, but it's not a horn, nor does it sound like a horn. You may want to listen to a pair first if your expectations are set around the sound of horn speakers. The ideal amplification for each of those types of speakers may vary dramatically also. The Quad will likely require a bit more muscle. Either would be best suited with tube amplification though (IMO).

Köchel is another horn option. Be careful that the speaker you select will work properly with the size of your room.

If you like the sound of horns, be very careful about purchasing another technology. I especially love the articulate horn loaded bass provided by the Köchel K300.

Edgarhorns and Classic Audio Reproductions are EXTREMELY good options as well. Duke at Audiokinesis is a trustworthy and knowledgable dealer that is familiar with differing designs.

Check out the Audio Asylum High Efficiency Speaker Forum for insight regarding horn technology. Just like other speaker technologies, there are many approaches to horn design, with some liking one approach over another. They are all good, but you will probably have a preference.

If you can wait until October, Rocky Mountain Audiofest would be a good place to hear a variety of horn designs.
