SDA 1c - Full Mods

Time to let someone else enjoy these fine speakers. Work/mods include: Sonicap Gen 1 caps, Mills resistors, poly switch removed, Cardas binding posts, all drivers Dynamatted and magnets glued, hurricane nuts installed, replaced bass inductor with Erse inductor, Black Hole 5 behind mid woofers, and RDO 194 tweeters. Exterior is all original. I would rate them a conservative 8 out of 10 cosmetically. Pick up 50 miles south of Chicago or I could drive to meet part way. Asking $700.00.

    didn't realize you were so close

    Thanks pitdogg. Listening to them right now and I wonder if I am doing the right thing. Same with the DCM Time Windows. I listened to them earlier today while I was on my computer in the office. Sigh. Where abouts are you located?

    Those are gorgeous, Faustin. I've always thought that the CRS were the right size for our apartment, but still . . . the 1c's are like twice the speaker! Is 200wpc enough power for them? What did you replace the IC cable with?

    Wow @Faustin those look sweet! And a great deal, IMO, since you did all the work! :smile: I'd be all over them (but I have 2 sets already)! :smile:

    200 wpc is plenty. Right now I am running an Adcom 555 which is 200 at 8 ohms and iirc 350 watts at 4 ohms and alternate between a Bottlehead Quickie tube pre and an Eastern Electric Minimax tube pre. . IC cable is Goertz Alpha Core speaker wire.

    Snag these while you can! Great deal for some fully modded 1C's.
    Taken from a recent Audioholics reply regarding "Club Polk" and Polk speakers:
    "I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion." :\
    My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

    I'm preemptively jealous of the new owner. Those are gorgeous examples.

    Very nice set of 1C's at a great price. GLWTS.

    Fully modded 1C's are a very special speaker. Phenomenal soundstage, especially with a tube amp.

    I honestly can’t understand why you would want to sell these and keep the DCM Time Windows. Good speakers, but they cannot handle dynamics or they’ll blow up!
