    Charge Coupled Crossover

    Where does one go for an education on charge coupled crossovers?

    What theory describes the benefits?

    I want to start with a replacement project for my 3106's. A very simple crossover indeed.

    I saw Zilch respond to one post on 3105's with "Build one your for $25, charge coupled for $10 more."

    Cool, where do I start?

    Thank you!

    Also, rather than retyping Ian's list, look at his post here with linked references back to these forums:

    Thanks T.D.

    That Gregory Timbers is one smart cookie!

    Those three pages explain it perfectly.

    Off to the electonics store, again.

    Ed Meitner passed the idea on to Greg and Greg incorporated the idea into his statement systems. This is one of two topics that should have stayed in the private forums due to it causing unnecessary fretting and confusion.

    What confusion? It is the act of taking any XO, removing the original caps and replacing them with Solen polyproplyene caps of twice the size and always in pairs. Then connecting the positive side of a 9v alkaline battery to the common point of all pairs.
    The result is a far superior set of speakers. The amount of money spent on CC networks, I spent about $150/ea to build completely new XOs, is well worth it.

    Hi, I'm planning to order parts from Solen.ca and build this xover for my 4344 (schematic attached) but then I just realize that there is no Low Frequency. Could anyone help explain where I would hook my bass driver to ? Thanks.

    The filter you show here is for active only.

    You need an electronic crossover and two stereo amplifiers.

    I made a typo in the network schematic I have posted the corrected diagam in the original thread.

    Further Charge Coupling question: has anyone tried a mismatched series of caps to get a capacitance value in between standard values?

    I.E. on a tweeter 1uF is a standard, so in charge coupling we would use 2 2uF caps in series. Would it work if I used a 4uF and a 2uF in series? The resulting value is not 1.5uF, but it is less than 2...

    4.7 and 2.2 are standard values though (if you -wanted- 1.5) ... 1.8 and 2.2 would get you 1.0
