brians7 Posted December 30, 2016 Author Share Posted December 30, 2016 What crossovers are you suing in Beautiful Belles? Quote Link to comment Share on other sites More sharing options...
Wolfbane Posted December 30, 2016 Share Posted December 30, 2016 I threw out the Klipsch AB Xo's that came with my Belles and replaced them with Bob's type A/4500 Xo's after upgrading the K-77 tweeter's. Quote Link to comment Share on other sites More sharing options...

Deang Posted December 31, 2016 Share Posted December 31, 2016 Where did all of the various values in the schematic come from - it looks like a kludge (not necessarily a bad thing). Quote Link to comment Share on other sites More sharing options...
brians7 Posted December 31, 2016 Author Share Posted December 31, 2016 Dean the values come from my poor understanding of a crossover network and to reuse the parts from the AB network. Al said it would not work and sent me a sweep Quote Link to comment Share on other sites More sharing options...

brians7 Posted January 2, 2017 Author Share Posted January 2, 2017 Ok after ordering hundreds of dollars in parts. I have come to realize the prices from our vendors for crossovers is more than fair. Well I am committed now. I will keep you guys updated as I make progress. Quote Link to comment Share on other sites More sharing options...

brians7 Posted February 14, 2017 Author Share Posted February 14, 2017 They are finally finished. I have been dragging my feet for fear that I hand made a mistake some where. Well I put one in the left channel and I am proud to say at least one works. Now only time well tell if I like it more the Deang crossovers.

brians7 Posted February 14, 2017 Author Share Posted February 14, 2017 1 hour ago, totalcomfort said: Nice layout!! Very nice work!! Thanks their is a couple things I would change probably. The first thing I would change is use a smaller hookup wire. And second thing would be drop the autotransformer and resistor in in the tweeter section which by the way is a 15ohm not a 10ohm Al said to changing it to a 15ohm would remove the sag seen in the plot. And third thing would buy the 3.5Mh coil from Bob. The cool thing about them is I can Bi-Amp or Try-Amp the if I choose. And I would like to Publicly think Al Klappenberger for his time helping me with this project. Quote Link to comment Share on other sites More sharing options...
