    Not to my ears.
    To my ears it's a clear upgrade, no doubt.

    To mine too... though I am using an analog PEQ to make a minor EQ adjustment in the lower midrange.

    I meant the schematics are available. You would need to build them.

    Hi Brian,

    It seems to me that some coils are not mounted as usually suggested.

    I think ivica is right, I believe one of the 2 coils on a board should be turned by 90° so that they don´t line up anymore. The coils will manipulate each other the way they´re mounted now.

    I am not sure what you meen ?

    The filters are original 67000 filters.
    And I can se that the placement of the coils are basicly the same as the 66000.

    "Crushed under this tombstone" is the desirable form for the true Everest 4x or 6x hobbyist EOL, i would think


    Rgd the networks, i think the components look OK with regard to coil cross-interaction (if not, where?), but improvements in component quality like Brian did for the bass units are also possible on the networks. At least measurable. If the listening experience improves that way is a very different question...

    When doing multiple driver swaps one might want to consider making a template like the factories use. A simple sheet of hard plastic with the bolt patterns enlarged. Place the woofer into the cabinet, place the template over the woofer and then have it with the screws. I consider myself pretty handy with tools but sometimes Mr. Murphy show up.
