    Wow, those look real nice. I don't think I am smart enough to do something like that. Great job.
    Oh, Listen here mister. We got no way of understandin' this world. But we got as much sense of this bird flyin in the sky. Now there is a lot that bird don't know, but it don't change the fact that the world is happening to him all the same. What I am tryin to say is, is that the course of your life, well its changing, and you don't even see it- Forest Bondurant

    Great job!

    Are you adjusting the Mid cossover point to the woofers? I have read in a few articles that seemed to question why Polk made that decision to use the 120hz point.

    If not out of line- What would a crossover like this cost to make or purchase?

    Thanks guys!

    No crossover points where changed.

    I wish it was an old beat up truck - that was a rather new Ford F150 doing that...

    Awesome. How long is your in-home audition period? Just kidding. These are very tempting. Nice craftsmanship.
