    4311 resurrection

    My first attempt at bringing a pair of speakers back to life. A pair of 4311A's.

    I got my hands on these several months ago. They actually sound pretty good to me. Though the tweeters are not in the best shape. I recently used these guys at a nye party everyone was blown away by the power and detail of them, damn fine rock speakers IMO.

    I intent to strip back the cabinets and restore the original Studio grey finish, recap and possibly replace the LE25's.

    I know there's plenty of 4311 restoration posts (I've checked out a few of them) I'm starting this one partly to get any advice as I go, partly to give me motivation to get it done, and because I thought some of you may find it interesting.

    The LE5-2's are in good nick and sound great, they are both measuring 6 ohms.
    The 2213's are also pretty good, reading 4.8 and 5.2 ohms.
    The LE25's are not great. the paper cones appear a bit creased and the sound of the upper range is a little lacking. Replace em? they are reading 4.5 and 5 ohms.
    So all these readings are well below the 8ohms, is this unusual?

    So I've got the 3112 crossovers. I notice one is painted black (No. 77581A) with the Caps marked "mexico" while the other is not black (No. 86318A) The pots also appear to have different numbers. One of the crossovers changed at one point? I'm gonna do the recap with the 2x4mF daytons, 1x3mF Dayton, and the 0.01mF Theta.

    As for the cabinets I started applying paint stripper and the layers of old paint scrap off pretty easily.

    As I said, I'm an absolute novice so any advice appreciated.
