These have the rare frequency control switch, probably one out of ten million pair...
The bonus is, you get to get ripped off at the police station.

Seems optimistic. But maybe that's just me. Foam on the right one doesn't look too good either.

Wow, what a deal.

What are the odds?
Here's another pair with the extremely rare contour switch. Only $600.
Not mine, no affil.

Does anybody know the history on this switch? I've owned and seen a LOT of Advent speakers. Never encountered a pair with a tweet switch. Very reminiscent of the switches in KLH speakers (e.g. KLH 6, 17, etc). Perhaps Henry Kloss copied his KLH design in the very first Advents?

Specifically which Advents have you seen without the tweeter switch?

The High Frequency Control switch is part of the OLA and NLA crossover. Check out the OLA and NLA crossover circuits at http://baselaudiolab.com/ADVENT_LA_XO.html They both have the switch. There is nothing rare about it.

Both my original Large Advent OLA and my new Large Advent (NLA) have the switch. My Advent/1 does not have the switch. My newer Advents don't have the switch (Legacy II and Baby III).

@RTally, yes, of course the OLA and NLA have the switch! Brain fart. For some reason I though the OP was referring to a later model, like the 5012, etc.
