Cerwin H-25
Not much is documented about the Cerwin H-25. The only period reference the Archive has found is a short product-news item in Sound and Communication (February 1986, p.43). It describes an H-25 compression driver with an integral horn. The same item mentions an oversized barium ferrite magnet driving a lightweight one-inch phenolic dome. Those details fit professional sound-reinforcement drivers of the mid-1980s.
The surviving text is publisher OCR and garbled in places. A frequency figure printed as "3 Hz to 20 Hz" is not credible for a compression driver, so it is not reproduced here. No production years, original price, sensitivity, power handling, crossover or application details have surfaced. The H-25 appears to have been a professional-grade driver, but the record is too thin to say more with confidence.
