If so, it sounds like I now have a new quest to work on. I find it very hard to believe that there is nothing out there that can closely imitate the ceramic speaker of that time. Ken
The first speaker, the one Weber was trying to clone, was alnico, not ceramic. Both were designed by the same person, Bob Gault, with ceramic being substitued as alnico became rare and expensive. Eminence was the company he started after CTS went under and to save money, he redesigned the driver to use less expensive magnets. They sound about the same, but since ceramic magnets are weaker than alnico, old ceramic magnet SVT speakers were 5-6 lbs heavier than their alnico counterparts to get the same amount of field strength.
There are other cabs out there that sound similar to the old SVT 8x10 coffin, but they all have their tradeoffs, whether power handling or volume or even weight when compared to it. There is nothing out there even remotely similar on an individual driver basis. Modern 10" speakers are designed around port tunings and are not made to be used in sealed cabs. Since audio power is cheaper than drivers now, speaker designers make them to have steep rolloff below resonance and high power handling. Ironically, cheap guitar speakers come the closest, as they are designed for maximum output overall, not just tuned efficiency. A friend of mine who built a coffin clone used Jensen Mod speakers, which are available in 32 ohms, another must
for the cab's tone.
