Arkytype Posted April 20, 2020 Share Posted April 20, 2020 Attached are two crossover network schematics of the Forte I and Forte II I found on the Klipsch forum. I assume these to be accurate. Note that the circuit topology is identical for both and with the exception of the inductor in the tweeter filter, all passive components differ only in value. Note also that on the Forte I schematic that the squawker is wired with inverted polarity but not the tweeter. On the Forte II schematic the tweeter is wired with inverted polarity but not the squawker. Can anyone explain the following: 1. Why invert either of the two drivers in the two Forte models? 2. Why was the squawker inverted on the Forte I and the tweeter inverted on the Forte II? I looked at a dozen or so Klipsch crossover networks posted on the Forum and found a few networks with driver polarity inverted. AL-2: squawker and tweeter AL-3: curiously, all drivers wired "normally". Heresy II: tweeter inverted Obviously, changes in drivers or network topology may dictate the necessity of inverting the polarity of one or more drivers to achieve a more uniform frequency response. But I find it curious that the Forte I and Forte II inverted different drivers in the two respective models. Lee Quote Link to comment Share on other sites More sharing options...
