This is a top notch piece, Clarity ESA, Jantzen + C-Coil, Supra internal wiring, Mundorf resistors! The only thing missing from the picture is the lexan substrate for the C-Coil.

    I try not to use the forum as a sales platform, just like to post stuff in the DIY mods section. If you would like to send an email to Vr3Mods@GMail.com we can talk more about that... :)

    Thank you

    Ok, as someone who has done the same exact crossover for my 4.1TL's, all I can say is that is seriously sweet dude. One question - why four binding posts per speaker?
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    Thank you sir!

    I converted them to a bi-wire.

    Is it just two posts in parallel or more to it than that?

    You remove the "J1" and "J2" jumper and install a 5 position Molex at the input. Instant bi-wire.

    And to be honest, This is the first one I have done like this and I missed the removing the J2 jumper. Will be doing that shortly... good question! :)
