The K-horns do a great job in their passband, but I want to build a sub that is as efficient in the octave below to match them, and do something to extend the high end as well. I estimate the sub portion of the project will require a pair of 15 inch drivers and a folded horn enclosure that is about 4 ft tall by 4 foot deep and eight feet long. It is probably large enough to install a K-Horn mid/high range driver set , and possibly a 15 inch direct fire woofer into, and work double duty as a passible center channel if I cannot find a suitable Belle. (This will be a project to try for fun)

The rears currently in my system are copies of Dunlavy Black Knights - A horrible mismatch. These cannot keep up (They'e inaudible when driven 1 to 1 with the K-horns, so they need 10-12 dB boost) The dam$ed Dynaudio drivers destroy themselves due to foam surround literally turning to dust with age, and that's accelerated when they are trying their hardest to move as much air as K-Horns. I also believe the 1 inch Dynaudio D21/AF tweeters in these towers are improperly crossed over (too much low frequency energy applied in an attempt to balance 2 12's and a 6) which causes them to incur failures with the voice coil leads or in the coils themselves.

I thought about modifying the enclosures to accept a pair of D21's to divide the load, and adjusting the crossover design to either move the tweeter's point up a bit and/or cross it over faster, but I am so busy with other stuff that I don't see getting to that point. I am probably ending up just replacing the foam surrounds in all 4 woofers, and dropping a pair of D21-2's in them and then giving them to my brother to make room for what I really want. He'll never try to do what I was with them.
