Carver AL III

Very nice, SLF. I am a fan of OB speakers and will have to keep my eyes open for a pair of these locally. Vintage Voltage 2015 should be coming up pretty soon and may be a good place to look.

Good luck tracking down these speakers, Nick.

The Andromedas are really interesting speakers and wonderful sounding. Carver still gets excited talking about them - I had a chance to chat with him a few years ago when I visited his repair shop. Mine are keepers. Here's a couple of pictures of the backs of the panels.

Whoa, what's happening there? Is that a cone driver into a horn divided by a baffle? To be a dipole? Hmmm...

With the 5 driver/ horns pointed up huh, almost omnidirectional, maybe? Then you have the dipole section with the woofers and fullrange drivers(?).

Yep, someone recalled that Carver was trying to get the spacious sound of planar dipoles using conventional drivers but also with lower distortion and better dynamics.

The cone tweeters are treated with a damping compound applied to the paper cone structure - "resulting in an absence of ringing and an extremely well damped but very slow tweeter" Transient capability is achieved through the network and an electronic motion control module. The entire system including the subwoofer totals 20 conventional drivers.

"Transient capabilities of the Andromeda III have achieved a new level of accuracy by the combined use of a large numberof high frequency drivers and elaborate electronic control circuitry. By using 20 drivers, Andromeda III combines the ability to operate at high volume levels, with very low distortion over the complete frequency range of 24Hz to 20kHz."

The subwoofer weighs 90lbs with two downward firing 12" woofers.

They need a bit more room around the panels than the Amazings do due to the upward firing tweets and the backward firing mid's. They are not placement fussy at all. Really interesting speakers!

With 20 drivers no wonder they were so power hungry!!
 
Were they an impedance nightmare or pretty well behaved??
