jackpod Posted December 4, 2006 Share Posted December 4, 2006 I have a pair of 1997 khorns with AK3 networks. What are the crossover points? I have a Marchand XM9-2 active crossover I would like to try Quote Link to comment Share on other sites More sharing options...
mark1101 Posted December 4, 2006 Share Posted December 4, 2006 I've seen 400/6000, and 350/5800. Not sure but in the ballpark. Quote Link to comment Share on other sites More sharing options...
jackpod Posted December 4, 2006 Author Share Posted December 4, 2006 Thanks Mark, I thought I had read about the 400 but had no idea about the mid/tweet point. Now to fabricate some resistor networks for those frequencies for my Marchand and I get to play Quote Link to comment Share on other sites More sharing options...
BEC Posted December 4, 2006 Share Posted December 4, 2006 Here is a trace I ran on a new AL-3/AK-3 last year. Bob Crites Quote Link to comment Share on other sites More sharing options...
JohnA Posted December 4, 2006 Share Posted December 4, 2006 The nominal crossover points are 400 Hz and 6000 Hz. Based on my experience, I'd use 350 and 5000 to 5500 for the tweeter (experiment). At least some K-55-Ms have a response return (bounce) around 7500, so I'd use a band-pass on the squawker to kill that. Quote Link to comment Share on other sites More sharing options...

John Warren Posted December 8, 2006 Share Posted December 8, 2006 comparing Bob's plot with the SPICE predictions gives me a warm fuzzy- Quote Link to comment Share on other sites More sharing options...
Ki Choi Posted December 21, 2006 Share Posted December 21, 2006 Bob: Based on your graph, the sqwaker extends as high as the tweeter. Am I looking at the graph correctly? Ki Quote Link to comment Share on other sites More sharing options...
djk Posted December 21, 2006 Share Posted December 21, 2006 Yes, you are. Klipsch does not roll off the high end of the squawker on most of their older networks. If you are tri-amping at 24dB I would try 400hz and 4500hz to start with. The LR4 rolls off the power to ech driver 6dB at the crossover point. Marchand has a Q control on some of their crossovers, it controls the response right at the crossover point. You may want to try 450hz on the low end, and peak the Q a bit.

ZAKO Posted December 21, 2006 Share Posted December 21, 2006 John.....Warm fuzzy? thats because your Binky,s on fire. Useing my electronic xover I find 450hz & 5500 optimum. Quote Link to comment Share on other sites More sharing options...
