    Personally I find they sound best with the trim pots set to 0 or close to. I think on mine the tweeter is a fraction lower than 0 and the mid is flat 0. I would start with this and then experiment. I did hear some not long ago with the mid turned to -3dB and whilst the owner claims it gave the flattest frequency response I find this impossible to believe as the mid sounded extremely recessed and almost like it had been disconnected! (It's easy to make a mistake measuring speakers).

    I'm not sure why you are being given the advice above. The drive units aren't intended to be dismantled and I'm sure you aren't intending to. However, unless you intend to grind the cones (both the mid and tweeter are pure beryllium) to a powder and inhale it you won't suffer beryllium poisoning.

    Sorry, you mean you were saving him from potentially being poisoned? Luckily, unless he is planning on eating any of the beryllium domes or grinding them up and inhaling them then he will be OK (from poisoning at least) - there's no beryllium dust/gas etc in them waiting to be released.

    If any of the drive units don't work I would recommend you claim a refund as replacement units are expensive and repair is, at best, a delicate procedure (if it can be done at all).

    Metallic Beryllium is perfectly safe when used in speaker diaphrams.

    cheers all.
    yes bought at auction and was told they were working before being entered for sale,if by chance somethings a miss i will probably break (which is a shame) due to the cost of replacement drivers let alone one turning up in the first place for sale!
    i wait with bated breath

    No, because they were bought at auction, that doesn't apply.
