First time guests to my modest home will usually end up asking, "is somebody playing a piano in the other room ?".
So I will show off my mighty oak Klipschorns, sounding like an actual grand piano while being powered by a
one (1) watt per channel, AA battery powered I-Pod dock.
After their initial astonishment wears off, I will then take them into my acoustically treated home theater room and introduce them to the sound of my hi-powered Klipsch Heritage audio system. Most people never feel quite the same about speakers after that.
I believe that for K-horns to sound their best, they need good solid corners. Notice that in my pictures, the corners are re-inforced with sections of low cost, used solid-core door slabs, cut to the height of the speakers. Some people use plywood, MDF or extra sheetrock. 32" wide panels are better than none. Paint it, stain it or staple some fabric on it. Klipschorns deserve better than single layer gypsum drywall resonance distortion. Enjoy the music!
