Best all around box speaker between 15K and 25K

My vote: Avalon Eidolons.

If this isn't an indication as to exactly how personal tastes can be, I don't know what is!

As my ex-girlfriend once said:

"What is annoying to one, is endearing to another!"

How about a Dunlavy SC-IV.

That was supposed to be Dunlavy SC-VI!

Get out and have a listen to the Vmps RM/X's, at around $10,000 a pair you will have plenty of cash left over for an active X-over and extra amp for a bi-amp setup of these monsters. http://www.vmpsaudio.com/rmx.htm

I have not listened to a pair of these yet, but have listened to their little brothers..Vmps RM-40's.
