these compression drivers that just found their way to me?
They are even larger than they look. The voice coil diameter is six inches. The overall diaphragm is larger than a Lowther. Preliminary measurements say that the low frequency ability will be basically limited by the horn. Do I get out my old horn extensions that I used for the JBL 2482 and drive them down to 60 Hz? Do I whip up a field coil and convert them first just to get rid of the "ceramic sputter"?? If I only use them up to 200 cycles, then does it matter how the ceramic sounds? I dunno...
I am sure they will be slapped onto a horn soon enough just to evaluate for potential. ...kinda like dave was in Lisa's post below... I am thinking the same will result... we can make these into something with only some time and effort.. :^)
They are here on long term loan... but I bet a field coil will happen rather quickly, don't ya' think?
Quad QA12/P Amplifier - This is pretty close to Quads first amplifier. I got to put my hands on one of these once very cool early British amplifiers. http://www.itishifi.com
