I'm putting some new crossovers in my L300s and I am PUMPED to hear the results. I've re-capped a few sets of speakers in the past, but since I don't know much about the science/art of crossover design I decided to outsource the job to someone who actually knew what the hell they were doing. Lansing Heritage member Duaneage was kind enough to volunteer to assemble these for me. I went with the Nelson Pass re-designed version of these crossovers. Dayton resistors, Jantzen cross-caps and superior Z caps were used. Duane did these RIGHT with custom etched PCB boards and serious soldering skills! :thmbsup:

I wanted the option of bi-amping these in the future without getting into external electronic crossover territory, so the crossovers were split into 2 separate boards - one for the HF drivers and one for the LF.

I got lucky with a bi-amp ready binding post assembly from PE - it fit the existing hole in back of the cabinets like a glove and looks to be a big improvement from the cheesy particle board and old binding post arrangement.

The biggest pain was getting the "foil-cals" off to install the L-Pads - a hair dryer to melt the glue and a small palette knife did the trick nicely.
I got one speaker done last night and was able to A/B between the new and old crossovers. WOW what a difference! I thought the old ones were good and couldn't imagine a HUGE improvement but thankfully I was wrong. Everything is SO much clearer and less grainy sounding in the HF. The bass is now shockingly well defined too - going back and forth between the two speakers (old vs. new xover) its amazing to me how seemingly blurred together all of the instruments are in the old vs. the new. Needless to say I am blown away and am putting in the second new crossover STAT :yes:. Thanks again to crossover guru Duaneange for his awesome skills and advice!
