Hi,

I don't think that was the tweeter, personally. There is a little "brightness" remaining with the Bicone Drivers, especially the Version you heard (those where off the shelf Supravox, the production ones have had their parameters adjusted to bring a little better balance in among some other things).

But equally, without the whizzer cone the speaker would cut off at 10KHz, meaning a Supertweeter becomes mandatory (this is the case for my current setup which uses a single cone fieldcoil driver). There the Supertweeters are very nice and not at all "bright". Drop in for a listen when you are in London....

Ciao T
