Pretty hot looking unit whatever it is.
If so that's one heck of a departure. :)Quote:

Note the frame colour and the magnet colour don't quite match on the 12".
Maybe the 8-Gs were a pair and the frame was busted, someone ordered the wrong replacement frame, mounted the magnet and voila!
Nice looking unit, quite unique I'd bet.
True, but you start with whatever existing components one has at hand...........Quote:

I suppose it was only a matter of time before they did it in the 12 inch frame.
How many 12 inch cone options currently exist? Various cones would make possible a range of "voicing".
I'm still trying to figure what would be the advantage of doing that with a 12" wouldn't they be real bass shy.A 604 can be bass shy if not in a pretty big enclosure.If they were used with a sub could be good I suppose.I think most Altec speakers using the 12" (414) use 2 with a small format HF driver.Just for that reason that they don't produce enough bass.Is this wrong ??? I just don't see the advantage of doing that with a 12" my thought would be to just use a real 604.I dunno :confused:
It works well if you are adding auxiliary bass units as the 12" can be crossed higher than the 15" and will offer higher power handling for the tweeter.

The small horn in the duplex would work with a 12" better IMHO...but again about opinions.:)
