    Just a personal thought......I might try to relocate that long resistor along the back of the board to clean up the look. I have never liked how those look cramped or wedged onto boards at odd angles.

    I agree, that's the only thing I don't like about the Dueland Resistors, but I will probably just leave it, it's been that way for a few years now..

    Here ya go Larry, The Red X's (with J5 in place) all connect to pad B and the Red Y's connect to pad G.

    Something I plan on doing to my CRS+'s is strip the cabs and take them to a body shop and have them painted a gloss black (Piano Black, no orange peel etc..) then (Hint, Hint) replace that piece off molding below the speaker grills with brushed aluminum of the same shape. If you decide to do the aluminum thing please let me know as I'm having a hard time finding someone who will do this without charging me an arm & leg plus my first born.

    Those look nice. Is it a must to use non-magnetic alloys when making the custom electronic/crossover housings?
  • Toolfan66Toolfan66 Posts: 14,292
    I have wondered the same thing, but I do see where it makes sense in doing so, but at the same time, most all amps, pre amps, CD players, blue ray players etc. have steel housings..

    I've had the idea to build external crossovers for my office speakers for a while now. One of the reasons being the components I want to use would take up way too much internal volume. I recently sat down to design the box and would love to have them made from aluminum, but may end up making them from MDF. Either way I think it's a good idea that they be non-magnetic.

    I had some spare 304ss, but held off making my crossover adapters, because machining it or a grind/polish returns it back to its magnetic state. I need to adapt the Erse inductors and will ask how they need to be orientated in my thread when they show up.

    I am loving how the internal wiring harness is looking..
  • Toolfan66Toolfan66 Posts: 14,292
    So I made a prototype crossover case that will mount to the stands, wanted to play with the layout with the 16mh inductor, what are your thoughts, back wall or side wall??

    You'll want it away from the steel frame, and 90 degree opposite from the board inductors on either plane

    Is any of it going to be see through? Might be cool to be able to see inside and have it light up or not to show off your work...

    Larry, I'm still in the planning stages, but thank you!

    I'm being lazy......did you color the Neutrik gaskets or do they sell them that way?
