    Forte IV

    in General Klipsch Info

    Posted

    In my opinion there are at least two serious avenues for improving Forte III: the middle compression driver using the same as on Cornwall IV, I remind you that the Horns are of identical architecture with the mumps, only the size is a little smaller on FIII. And also the new diffusion piece of the new K107Ti from CWIV and HIV for better treble.

    Hello and welcome to the forum!

     

    Here is the connection for a passive bi-amplification, don't forget to remove the jonction plates on the RF7II terminal blocks :

    Will the existing capacitors have their value on the side of them? Or will I need to open them up to see the values? 

     

    other example >>> 2MFD = 2µF on grey klipsch original métal box capacitor and 15µF on White Sonicap

    MKP = polypropylene film capacitor, these are the best capacitors for network speakers.

     

    If you don't want to bother chose the Bob Crites Kit, because he had the capacitors made with the correct values for filter B = 4 and 2µF.

     

    On the other hand, if you are a DIY enthusiast you can order capacitors of standard values and combine them in parallel to make the right value. In this case you can order capacitors known for their sound quality, I recommend Jantzen superior Zcap red, I told you above to check the values of your filter and if you have 4 and 2 µF made 4 with 3.3 + 0.68 and 2 with 1+ 1.

    It's for Heresy or KHorn, but it's the same for Cornwall, just look at the values of the capacitors to change on your network

     

     

    If you want this kit >>>>> https://critesspeakers.com/crossover_repair_kits.html

     

    Price >>>> https://critesspeakers.com/prices-crossover_repair_kit.html

     

     

     

     

     

    If you put MKP it will look like this at the end

    Show us pictures of your networks and capacitors with the values written on them 😉

     

    Normally your Cornwall type B has 2 capacitors, 1 of 4µF and 1 of 2µF.
    To replace them by MKP you can make 2µF with 2 capacitors of 1µF in parallel. To make 4µF you can put for example 1 of 3.3µF and 1 of 0.68µF in parallel it will be 3.98µF it is similar to 4µF

     

    Here is the diagram of Network type B of Cornwall
