I'm still looking fora pair of 2.3's near me but I do like these speakers.

    Re-capped and repaired my 1Bs perhaps a year ago. I'm TOTALLY THRILLED with the result.

    I followed the thread started by inspiredsports pioneering the 198 tweets in the 1B/SRS 2 blade/blade speakers. (Replace the 4.4uf capacitor with a 5.8uf cap on each HF board, and buy four RDO 198s.)

    Beyond that, I used inexpensive film caps and non-inductive resistors. If I were doing it again, I would absolutely use the Mills brand resistors as their physical size is smaller than what I bought.
    Dayton 1% caps for the HF circuit board
    Removed the polyswitches and did NOT add additional resistance to compensate.
    Dayton 5% caps and Erse PulseX 3% caps for the LF circuit board.

    Have not changed inductors. Don't have any real urge to, either; although some folks that have upgraded the inductors wax poetic--and I wouldn't deny the possibility of sonic improvement.

    Two photos of the LF board components. Not sure I have decent photos of the HF boards.

    Also installed damping material on the MWs and passives; and attached them to the cabinet with rope caulk instead of the OEM gaskets. Had a defective tweeter so they certainly weren't sounding their best before the project started, but I sure am lovin' them now.

    Also did an internal wiring bypass to allow for future AI-1 use; but I'm no electrical engineer and that mod did not work out as well as I might have hoped. I can use either the original blade/blade interconnect (sounds great) or the single-conductor-with-ground interconnect (sounds less than great, but not hateful.)
    Clearly, you'd not need to include this mod.
