    I was very skeptical of reports that they did anything at all, until I tried a set. Whatever they are doing - and it could be some comb filtering effect - they certainly do have an impact on the sound, and not just in the high frequencies. Any supertweeters I've tried other than these put out something audible from 8-10k, these don't.

    I guess having two pairs would only increase the output by what, 3db? But might be interesting regardless.

    I did stick a reasonable quality gainclone in as an experiment, driving them directly from that, in an attempt to cover for the mismatch in sensitivity, but without a suitable measurement setup I was just messing around really, and things sounded more 'right' running them off the main amp.

    If that's the case, there was something wrong with the setup. The filter was rolling the units in too early from the description. There should be no audible output from supertweeters.
    It is impossible for anything digital to sound analogue, because it isn't analogue!

    Well you could certainly hear something from Townshends I've owned, and Tannoys, and Audiosmiles ....

    The takets are reportedly the only ones to be silent - I've toyed with trying their batpure further up the range, open backed as I think this could add some extra ambience - but the new Tannoy look sooooo lovely.

    I set up my own supertweeters and filters, which were carefully tuned to avoid audible output. But, you could certainly hear a difference in the sound when they were taken out of operation.

    I've not used any for years though. I have many suitable drivers, but can't be bothered to be honest.

    All supertweeters will seem silent if used properly, i.e., filtered to come in above the audible treble output from the main tweeter.

    Ive heard output as well but if, as Geoff says, the right filter is on it, you shouldnt

    I have external crossovers placed next to my amp. Could I run these things straight from my tweeter terminals i.e. post crossovers or would something nasty happen impedance wise ?

    That's what I do. Their impedance is very high and I'm repeatedly assured that it's nothing to worry about.
