    Omitted Build Notes:
    6. five coats of Flex Seal* applied to interior - something different & untried
    7. Armaflex on mid magnets, frames, & closure walls - as w/the other speakers
    8. mineral wool gently tucked in between Power Port tubes & closure walls
    * does, by its self, help to reduce closure ringing

    Update. Everything XO'd @ ~2K, 4th order. I expect some heat for this.

    Did a bunch of listening w/the XOs set as closely to Polk's specs as possible. Then I reset them to the above. Seemed cleaner, w/ the same FR. Makes sense given that those mids will beam above 2.3K.

    Polk specs their filtering, all 2nd order, as follows:
    tweeter: 2.2kHz
    mids @ 1.5kHz & 3.8kHz, -6dB

    Side note 1: triamping my center increases available power to 100 watts per driver. Added a real 100+ watts across my front.

    Side note 2: discovered my pre/pro allows English or metric distance settings - increments either 6" or .1 meter = ~4".

    Enjoy.
