    Wow Wow Wow (as usual)! Will there be a switch for the tunable high freq circuit or is it movable wires on a terminal block? What adhesive works well for adhering the wood veneer to the Delrin?

    Also, what are the metal cutting capabilities of your CNC laser? I don't suppose it can cut steel can it?

    Thanks guys!

    Yes there is a terminal block that you insert a wire to bypass a resistor to adjust the highs. When simulating the crossover, I noted the rise and added a resistor to adjust it slightly back to flat.

    The wood is actually quarter inch solid burl, but then it is backed by a quarter inch piece of delrin. I used power grab ultimate which seems to work really well as long as you sand the delrin.

    The laser can't cut or etch metal but you can use a spray to "engrave" it but that is really a chemical reaction more than anything. A laser capable of doing cutting is way way more powerful and much more money

    I like the laser cut "Twenty.22" on the front of the felt pad.

    You know when the crossover box is as big as your speaker box...things are heading in the right direction :-p
