I am in a maelstrom of kit-shifting (and now computer-cleaning, it seems!)
and have finally got round to trying an old pair of homemade standmounters
that have dwelt in the 'speaker heap', in my garage, for the last couple
of years.

I've put 'em on and they sound quite amazing! (I'm cautiously thinking
they might be the perfect solution to my current problems with terrible
room acoustics - bass honk and resonance).....

They are paper drivers - both the tweeter and the bass driver. (What a
blessed relief after Kevlar cones - now sold!) But the mystery is the bass
driver - it's about 7 inches Ø and has a smaller cone about 3 inches Ø
protruding from it whicjh is rather like the last inch of a trumpet's, er,
bell end! (Can't post a pic atm!)

Anyone ever seen the like?


If you happen to like building valve amps too, these are probably just
what you want. They should sound great as they are probably quite
sensitive (those paper cones!). You don't get a flat frequency response,
but they will probably sound very nice. It may be worth pairing them with
more modern dome tweeters though as the cone types tend to be very
directional.

The extra cone is known as a "parasitic" cone and tends to add mid-upper
mid response to the main cone. Sometimes they are "damped" with a foam
ring on the outer edge to control its resonance.
