I had Dean build me some custom crossovers for my custom K-Horns a while back. I needed them to be adjustable since I'm using different drivers and horns. I had been using and older pair of home built universal type crossovers with Dayton and Sonicaps capacitors. After I got the new crossovers, I started listening and tried different attenuation settings on the mids and highs(with ALK tweeter attenuators in the mix). I tried at least 1047.2 different combinations over the next few months until I got the sound right. Much of that was due to the fact that the caps were still "burning in", along with my ears getting used to the sound. I am a firm believer that 100 hours is minimum acceptable time for a decent settling in on components and ears.
This is where I start getting mad. After getting everything dialed in, I started noticing bothersome room reflections, and a nagging wife in the other room telling me to turn it down. I realized that the sound was so much clearer that I kept turning up the volume until I was overwhelming the room with too much sound! Another annoying thing is that I was hearing so much more detail that I had to listen to all my favorite LP's over again as if they were never heard before. Here's the last straw. I am a vinyl only kind of guy, but my dog likes to jump off the couch and skip my records from time to time. So one day I decided to throw in a cd so I could have some music playing without worries of doggie destroying a precious lp. I'll be damned if that cd didn't sound good. Or the next ten. How am I ever going to live with myself?
It is truly amazing how much better my system sounds with the new crossovers. I don't think Dean gets enough credit sometimes, and people tend to think his prices are too high when they can get other peoples crossovers so much cheaper. The components Dean chooses are not cheap, and he has done his homework on the synergy between parts that makes his products shine.
