K-horn won't fit, any other corner speakers recommended for a big room?

You might look at Pi Speakers.  A couple of their models are designed to go into corners. 

I first heard the 7 Pi at the Midwest Audio Fest many years ago.  I knew nothing about them and had no idea what was in the room, and from where I had to stand (because of the crowd in the room) I could not see the speakers, but from outside of line-of-sight they sounded absolutely incredible.  My jaw dropped when I was finally able to enter the room far enough to see the speakers.  I had no idea I had been listening to horns.  Designer Wayne Parham is superb, every design I have heard of his has been excellent, but his specialty is (arguably) speakers designed for placement in the corners.

@tsushima1  yes, budget would be helpful.  I’d like to stay under $5k if at all possible.  
 

@audiokinesis   I have been looking at the 7 Pi for awhile and have considered it as my last alternative.  I have built a few cabinets as well as speakers in my day, so the option of building a pair is real, but with this prior experience I also know how much time that takes to get woodworking to my standards.  Your first hand experience is the first that I have read outside of the Pi website so that is very encouraging.  To be honest, as I have followed Agon for several years now and have read many many comments and opinions of yours in particular, I take that experience and commentary as the gospel truth.  No BS at all.  The same goes for many of the responses that have been shared on this thread.  It is an honor to get opinions and help from those that I hold on high regard.  Thank you.  

I agree with @mrdecibel 

Tight in corners is no good for any heritage speaker except a khorn. Even the cornwalls can benefit from being a ft or so away from walls. My LaScalas are a couple of feet away from the corners (where the subs reside) and they sound just grand.

So my suggestion is for a Cornwall IV if khorns or lascalas are a no go.

I have not heard the new Khorn other than in a corner, so I cannot say from my own listening experience, if they were to be excellent set up in free space, away from all walls and corners. But I speak to many Klipsch and Khorn owners ( I am talking about the new AK6 ), and none are using them far from the corners, based on their listening preference. However, based on my readings and research, the dog house on the new Khorns are ( just imo ), designed like a slot loaded sub, kind of like the older Janis W1 and W3 subwoofers, designed by John Marovskis ( I believe this is the spelling ). I met him at his Bronx warehouse on 2 occasions, once for a pair of W1s, and another for a pair of W3s. Read up on the design. If I am wrong about this, so be it, as I have been wrong once or twice before...lol. To answer @kren0006, my description of what happens ( from my own listening ) when placed in a corner, is true on all Klipsch ( again except Khorn ), and, most speakers. Corners are acoustically problematic, ime....but, if the corners are the only place for speaker location, get the speaker that has all of the other attributes you are looking for, as nothing will be optimum in a corner, but can still be enjoyable. My best, and enjoy ! Always, MrD.

@speed005 did you ever make a move?

@audiokinesis absolutely!

I am a proud owner of 7pi corner horns, and I’ve never heard anything so relaxed and smooth, yet dynamic and punchy ant the same time (in my typical domestic settings)

They put my floor to ceiling line (full range) arrays to shame in the way of “punch and drama”…

The arrays do have their advantages though…just completely different.
