    Default Polk Audio SDA SRS Modification Thread Part 2 - The "Ultimate Build"

    So I have the rare opportunity for someone to bring me the speakers in person! They are making the trek from Virginia -

    Will start the thread and update it upon completion -

    Specs of the build -

    Tweeter Network -
    Clarity Cap MR 400v
    Clarity Cap ESA 250v
    Duelund Resistors
    Jantzen Inductors
    Supra Rondo 13 awg Internal Wiring

    Midbass/SDA Network -
    Clarity Cap MR 400v
    Clarity Cap ESA 250v
    Jantzen Inductors
    Jantzen C-Coil SDA Inductor for the lowest possible DCR

    Other Features -
    Updated shelf design - will be mounted inside the enclosure, front to back with a "flipped" front that opens up to a clear lexan window on a custom built faceplate that will be built for a beauty view of select parts, most likely a Duelund resistor and two MR caps and an engraved plate. Will be looking into a battery powered led with a switch to light this area up. Custom rounded handles, little wider than the stock flat handles for a more modern design.

    Clear lexan substrate versus delrin, .25" thick - will be using tech flex/heat shrink for the internal wiring for the cleanest look

    9 AWG SDA Cable, NL4 connection

    Custom round aluminum termainl plate

    WBT Binding Post

    Hurricane Nuts for all screw locations

    Dynamat driver baskets

    No Rez or Sonic Barrier for the enclosure walls

    "Custom Bass Brace" that is a "cage" design that attaches on four points on the back of the speaker with head duty rubber isolation mounts that will aid in an earthquake as well as accomplish the point of the original bass brace.

    Attached is a concept of the original chassis design which has already changed.

    1st Quarter Update!

    After extensive R&D on the new shelf platform I came up with a fully isolated design that will be a three piece build. I am excited, the fabricator is building them now. Very excited about this build.

    I upped the aluminum to 1/8" thick, 6160, the front panel is 1/4" thick and the Lexan substrate is 1/4" thick. All aluminum hardware will be used on the shelf system as well.

    Pictured below is the internal wiring and No Rez installed.

    Since those were delivered makes all the sense you would take on that big boy project. When done I'll be very intersted to have a look at the see through features ala the glass back Ferrarris that show off the v12. Do you also take in on shipped items regular sized speakers to do whatever they request? Btw the cross overs settled in beautifully and listeng to them right now. Again can't thank you enough to work w/ me and then the whole mis delivery deal which really scared me. It all worked out.
