cfelliot Posted December 18, 2009 Share Posted December 18, 2009 I had to open up one of my Heresy IIIs to replace a bad mid-range. To my surprise the autoformer is now gone from the crossover replaced with resistor networks to match the different efficiencies. Was this done to all of the new Heritage line? Anyone seen schematics of these new networks? Quote Link to comment Share on other sites More sharing options...
BEC Posted December 18, 2009 Share Posted December 18, 2009 Correct. Klipsch no longer uses autotransformers. Bob Crites Quote Link to comment Share on other sites More sharing options...
kg4guy Posted December 19, 2009 Share Posted December 19, 2009 Was this done to improve the crossover or is it a cost issue?[*-)] Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted December 19, 2009 Share Posted December 19, 2009 Cost is my bet. Those autoformers contain a noticeable amount of copper. Resistors are cheap, small and light. Quote Link to comment Share on other sites More sharing options...
cfelliot Posted December 19, 2009 Author Share Posted December 19, 2009 I didn't count, but they're loaded with copper. I think I counted 4 coils. And, maybe 6-7 caps. Then the resistors! I'd love to see a schematic! Quote Link to comment Share on other sites More sharing options...
boom3 Posted December 20, 2009 Share Posted December 20, 2009 My impression is that all the current Heritage crossovers are new designs, not just the use of resistors versus autotransformers. Quote Link to comment Share on other sites More sharing options...
cfelliot Posted January 14, 2010 Author Share Posted January 14, 2010 While I had it open, I took some pictures of the H3 Crossover. The top board is the HF crossover and the lower is the LF crossover. Quote Link to comment Share on other sites More sharing options...
Islander Posted January 18, 2010 Share Posted January 18, 2010 I'm no crossover expert, but the H3 crossover looks a lot more sophisticated than the H2 model. I was impressed with the improvement in sound of the H3 over the H2, but so many of the components, including drivers and tweeter horn, are changed that it's hard to say exactly where all the better sound comes from.

neo33 Posted January 18, 2010 Share Posted January 18, 2010 Why is there three set of Banana Plugs with the middle and the lower not pluggable and the top labeled "HF", the lower labeled "LF"? BTW, how do you put multiple pictures into the same post with no .jpg file in the header? Quote Link to comment Share on other sites More sharing options...
cfelliot Posted January 18, 2010 Author Share Posted January 18, 2010 There is no middle. That is a reflection of the LF connection. Those caps on the connectors are removable to accept a bannana plug. Whatever the changes from the H2, the H3 is an awesome sounding speaker. I cross over to subs at 100hz so I have no lack of bass. I should listen to them without the subs sometime, but I know I won't leave them that way. I'd still like to see a schematic of these crossovers?

neo33 Posted January 18, 2010 Share Posted January 18, 2010 Oh, I get it now. Your amp goes into the "HF" and the sub goes into the "LF", correct? Quote Link to comment Share on other sites More sharing options...
Islander Posted January 18, 2010 Share Posted January 18, 2010 The sub would not be connected to the main speakers. The "HF" and "LF" indications are for the convenience of someone who wants to bi-wire their speakers. For normal wiring, the wires can be attached to either the HF or LF connectors, as the jumper straps will carry the current to the other connectors.

cfelliot Posted January 18, 2010 Author Share Posted January 18, 2010 No, the HF and LF connections are for bi-wiring or bi-amping. I do neither, hence the shorting strap is in place connecting them together. The H3s are driven from a Bryston 2B. I have a Yamaha receiver that I use the power amp sections only for the center and surrounds. The L/R feeds the Bryston. The subs have their own power amp an Anthem MCA-20. The Yamaha sends all signals below 100hz for all channels to the subs. Quote Link to comment Share on other sites More sharing options...
neo33 Posted January 18, 2010 Share Posted January 18, 2010 Okay, I got it now. So the covenient of bi-amping is added to the H3s. Quote Link to comment Share on other sites More sharing options...

Invidiosulus Posted January 19, 2010 Share Posted January 19, 2010 You can do it through the wysiwig editor as well IF you have the images hosted on another site. click the little tree button and then paste in the location of your file. Or as cfelliot said you can edit the html directly which is totally more 1337. -Josh Quote Link to comment Share on other sites More sharing options...

The reason for doing it in HTML is that it is way faster than adding them via the GUI interface when they are only different by a couple of characters in the image filename.

cfelliot Posted January 19, 2010 Author Share Posted January 19, 2010 When you are composing a message, insert the first image and then switch to HTML mode. It's the icon next to last on the message toolbar. This switches to HTML mode and you can copy and paste sections and then change the filename. Note as stated above this only works if you have a URL to the image stored on some other site. You need to know very basic HTML. There are some great tutorials on the web.
