    The cap is like a .22 uf (extremely small) - cost approximately $40.00 - if you were replace the 12uf caps it adds about $1500 on to the price, give or take so it can get pricey quick...

    I do *every* speaker that comes through here right side positive, just to be consistent.

    There is no right or wrong though, as long as you wire it with the correct polarity..

    I would do one vertical, horizontal and flat just to make sure. Better safe than sorry

    I am interesting in seeing our final product, are you going to leave it exposed or put it in a case?

    Very nice!

    The 6.8uf MR looks odd.. :-P - Looks like a 5 hour energy drink!

    Yeah, I use the 6.8uf as well, never used a 6.8 MR though, hehe

    This is true.

    The big one I am working on the only stipulation to it was "It has to drop in and that's that" so... ya know... :)

    The MR is like the cocaine of speakers...

    The true down side to the MR is the burn in, an easy 250 hours before it even achieves 25% of its performance then a switch just goes off. It is the one audio experience to this day that floors me.

    I guess you could maybe go to Duelund caps, $800 or so a piece - better or worse, preference? Hard to say

    Hey Larry!

    Why don't you use NL8 connections for your internal wiring if you are going external, or better yet -

    Ah, sorry - I saw the Molex on the layout and was curious...

    NL8s are incredible! :)

    I feel it needs repeating once more - those caps are enormous!

    Great work, Trey.
