klipshorn speakers

1+ jallan, any frequency response problems can be managed but there is no way you can get them to image properly. They will do the basic 2 dimension image but that is it. You will never get that sense of space around the instruments like they are standing in your room. Jallan is probably correct. The woofer is five feet behind the rest of the loudspeaker and the midrange 18" behind the tweeter. You have three different group delays. We had them in the store comparing them to Magneplanar 3.6i's and the difference in imaging was night and day. It would be an interesting experiment to tri amp the K horns and manage the delays digitally to see what happens.

If he's a newb, don't waste his money on a K-horn for head banging music; get a pair of vintage Cerwin Vegas and tell him to rock out!

A pair of klipschorns will be wasted in this situation. The recommendation of a pair of CVs is spot on, although add a pair of cheap subs for good effect.

I'll bet dollars to donuts the OPs son doesn't have a room that will support khorns. IMHO you need to have them on at least a 17' wall to get the best performance. But when the stars align, you'll be hard pressed to beat them without spending a lot more $$.

I had K-horns for a while some time ago.

I sense this thread isn't going to make any difference whether or not he'll purchases them. I assume he's obsessed with owning a pair, and I can understand the lure.

However, your son is on the wrong path for his intended use - these are probably one of the worse speakers for playing loud and retaining any real musical qualities. There are so many other choices he would be much better off with, but he's likely not entertaining other options, which is too bad.

Hopefully, this failure will be a good lesson for him down the road.

If your son is still living at home with you..throw him out
