In Reply to: RE: Don't miss the CAR room... posted by Bill F. on September 30, 2009 at 07:57:25
The new T-1's with the Field Coil Drivers (NOT TAD) and the Edgar built Horns is worth the flight to Denver.
No comparison whatsoever with earlier CAR designs which used TAD drivers.
That said, I have heard the TAD driver CAR Hartsfelds sound decent and in fact quite good, at CES/THE show in Las Vegas a few years ago.
But a RMAF they just drive me out of the room.
Go figure.

Don't blame the TADs. It's all the horns and/or implementation that results in bad sound (if any). TAD components are about as good as it gets, better than JBL generally in terms of engineering and build quality. Bert Locanthi, the brains behind many of the JBL designs from the golden age, went to Pioneer to start TAD. They basically gave him carte blanche to do what he wanted, which was what JBL could have been if they had the funds and dedication. (IIRC).
That said, I've never been partial to the CAR speakers, they always sounded edgy to me.
Is Josh showing at RMAF? He's been working on some pretty impressive field-coil drivers.

are modified with field coil magnets on the mid bass(D140?) and mid compression driver (2441?) and custom make beryllium diaphragms on the Edgar designed mid horn and horn loaded tweeter.

I did notice that, but still, I think TAD surpasses JBL as far as overall driver design. What the FC motor brings to the picture, I don't know. I bet FC TADs would be sweet! ;-)

THE REASON I DID NOT BUILD THE FIELD COIL MOTOR FOR THE TAD DIAPHRAMS IS QUITE SIMPLE. WHILE THEY WERE CLOSER TO CUTTING EDGE AT THE TIME THERE DIAPHRAM DESIGN IS OBSOLETE' THE BERYLLIUM DIAPHRAM IS TERMINATED ON A BERYLLIUM SURROUND. VERY STIFF CAN'T BE PROPERLY USED AT LOWER FREQUENCIES AND HAS VERY POOR YOUNG'S MODULOUS SPECS.
MUCH BETTER RESULTS WERE OBTAINED WITH HARMON'S 2435 UNIT GOTTO MADE FOR THEM. BUT THE DROPPED THE BALL HALFWAY DOWN THE FIELD WHEN THEY MADE THE 4" UNIT FOR THE NEW EVEREST SYSTEM.
