I compared them to Bozak Concert Grands with the line array and purchased the Grands. I later compared Khorns to stacked pairs of Mcintosh ML-4C and chose the ML-4c driven by 2 MC 2300. Lately I compared K-horns to Magico Q5 and if I had the money I would take the Q5. I also compared the Khorns to XR 290s driven by a 2600 and the 290's won easily. The speakers the Khorns did beat were, JBL Paragons and Hartsfield (no highs), Altec Carmel, Capistrano, Magnificant and A7-500, EV Patrician and Georgian and Model 6, JBL Olympus was a tie, but I thought the 4435 was a better speaker as were Urie big monitors with either one or two extra 15" woofers. There are very few speakers with less than 93 db sensitivity that can equal a corner horn. But it it isn't always a matter of quantity, but the guilty that I feel is more important. 110 db peaks is about all I can take, thats only 10 watts to Khorns in my room and about 50 watts to my Grands tri amped with added super tweeters. .The ML-4c stacked required 400 watts. The XR 290's required a little over 200 watts and they and the ML-4 would reach 16 hz, which a Corner horn can't. .
