I recently picked up a pair of Electro-Voice DH1506 compression drivers (CD) to upgrade my CF-4's. There was nothing wrong with the stock K-63's, but strong endorsements from Moray James and Alexg5775 got me wondering if the already fantastic sounding CF-4's didn't have a little room for improvement. I A/B'd the K-63 and the DH1506 and found them very close in sound. My testing was very informal and the sound was slightly better in the midrange with the DH1506. I wanted to get them measured properly to see if the diaphragms were within spec, so after a quick call to Mustang Guy I was off to the Speaker Ranch to get them measured. As usual, Craig had a better idea. I call his place the Speaker Ranch because his building is so large it's like a free range area where Klipsch speakers can wander and play freely, as loud as they want. There are fully 6 La Scalas set up in a 6.2 configuration, sometimes more. See Mustang Guy's signature for the entire list. It was around 20 or 30 last time I checked. Craig immediately grasped a 1506 which was attached to the CF-4 horn and connected it to the squacker section of the right side La Scala. Then we listened. We set up in the main LP and could hear an immediate difference, probably in favor of the DH1506. I say probably because this was NOT a controlled test, it was very much seat of the pants. We both thought the DH1506 might have been more efficient making that side a little brighter. If there was a difference, it was very little, both CD's sounded fantastic. Certainly one CD could be used interchangeably with the other and in a blind listening test you could not tell which was which. Craig took some measurements of both CD's in a very interesting way, so I think I'll stop here and let him post his comments.
Hi fellow Klipsch fans! Long time since I have visited. I have been enjoying my KHorns without even feeling the need to tweak or change anything! I know, hard to believe Until today, when I heard this faint buzz / distortion. I couldn't tell if it was mechanical or signal. So I started basic signal flow t-shooting, and found my right K-55 to blame. So now what... Well I start to take apart the k-55 using the instructions found here . All looked normal at first. Reassembled hoping that whatever it was had been resolved . Still there. So I take it apart again. This time I look close at the voice coil, and I see that it is a bit of fuzz on it. Distilled water and a cue tip clean it up no problem. Reassembled, and the buzz is gone. Some pretty simple maintenance took care of it. Just wanted to through this on the forum in case anyone comes looking for a k-55- buzz like I had. While I was in there, I also trimmed the red gasket so the excess did not impede the throat of the horn. Well, back to enjoying my Klipschorns!!! TG
