I had my AK3 K horns on a ~15ft wall in a 23ft long room, main seating was about 12ft from the speakers in the middle of the room... while the K horns sounded good overall for lower or mid volume listening, they had too many issues that made them hard to enjoy on a regular basis. Mainly the unbalanced midrange that required tone control adjustment as every song/recording was different needing frequent adjustment. The bass was great when it was good but very finicky, would sound good in one spot on the "U" shaped couch but terrible on the other end, same for different places in the room, strong at the back corners but less in the main seating position and almost non existent only a few feet away at other end of the couch or side chairs.
Another thing I really didnt care for was how too many recordings sounded bad on them, yet other klipsch speakers like CF4, KG5.5 and forte/chorus2 or other brands sounded fine on same recordings and same system. Also noticed the time alignment issues these speakers have, smaller rooms seem to be worse for this since the speakers dont have the room they need to breathe or let the sound stage expand like it can in bigger rooms with higher ceilings. When listening louder, all those things mentioned got worse, as good as the bass can be, up louder the mids overwhelm everything and the bass knob or loudness button needed to be turned up to compensate.
As mentioned above and something I say all the time... far too many variables to say they will or wont work in any given room, system or a persons taste in music or volumes they listen at, but after owning 2 pairs of these speakers, 1 AK3 and 1 AA, they are just to difficult to make them sound right in a smaller room for the majority of music I listen to which is mostly classic, modern and alternative rock music.
Dont get me wrong, they are great speakers that can do amazing things when all the stars are aligned just right and I'm sure much of the problems were related to the smaller room, but when other speakers sound good on the same recordings/system/room, that indicates the K horns were just too finicky and picky in a smaller room with mid-fi solid state gear. I am much happier with my current set up of chrous2 and dual SVS subs in that same small basement for music, I run Definitive Technology speakers for movie use but they also sound very good for music. And since you are a epic speaker guy, I liked my CF4's the most of all my speakers so far, I actually sold them and some other speakers to fund the K horn purchase, but I sold the Khorns a couple years ago when I got an offer for 2x what I paid. Maybe will own them again when I get a bigger house. The good thing is, if they dont work out you can sell them for what you paid or more if you get a good deal.
Hope they work out for you, just dont sell the epics before you decide.
