Cerwin 250SE
Little is documented about the Cerwin 250SE. The surviving record is almost entirely a single period test report, published in the "Test Reports" section of HiFI-Stereo (September 1986, p.60). The review's descriptions and measurements are about all that's known.
The 250SE was a loudspeaker with variable midrange and treble response adjustments. The report found them unusually effective. The controls could reshape the response so strongly that the speaker could be voiced to almost any character the listener wanted, within wide limits. Measurements showed a high-frequency rolloff above 15,000 Hz and a periodic response variation with peaks spaced about 1,500 Hz apart across the entire band. On musical program material, the woofer was the only driver the reviewers could push into nonlinearity. The midrange and tweeter held up. The tweeter had an elliptical cross-section, mounted with its longer axis horizontal, which HiFI-Stereo (September 1986, p.58) said gave it better directional properties than a plain dome radiator. Beyond that test report, no original specifications, prices, or sales history for the 250SE have surfaced in the archive's records.
