GLFMD56 Posted November 20, 2008 Share Posted November 20, 2008 Here is my dilemma; I have Forte's and Heresy's powered by a Sansui AU D9. Recently I re-built both crossover networks using high end components. The Heresy XO capacitors have been upgraded with Mundorf SIO and the Forte with Mundorf Supreme, Sledgehammer Inductor, Dayton Wire Wound Resistor. While playing these side by side, the Forte sounds extremely closed in and muffled, while the Heresy sounds open and clear. The Forte's have a sensitivity of 98dB while the Heresy's have a sensitivity of 96dB, so if anything, the Forte's should sound louder which is not the case. The Forte capacitors only have about 25 hours on them but I find it hard to believe that after 100 hours or so they will magically open up. At this point I am questioning whether the tweeter and midrange horn magnets could be weak (all 4 unlikely), or maybe the spring clip terminals are effecting the sound, or I have wired something wrong (checked it twice). I have provided a diagram of my XO layout. Any suggestions would be greatly appreciated. Thanks! Mike Forte XO.pdf Quote Link to comment Share on other sites More sharing options...
BEC Posted November 20, 2008 Share Posted November 20, 2008 Mike, On your drawing, is the point where the 47uF cap, 40 ohm resistor, and .16mH inductor connect also connected to circuit (-). It should be. I have attached the schematic for the Forte. Bob Crites Forte1.pdf Quote Link to comment Share on other sites More sharing options...
