Cerwin Vega DX-7

Little is documented about the Cerwin Vega DX-7. The HiFI-Stereo May 1992 issue tested it (p.48) and measured it at a sensitivity level equivalent to 90 dB SPL. The review noted distortion between 0.2 and 0.4 percent from 60 to 250 Hz at that level (HiFI-Stereo, May 1992, p.48). The reviewer also remarked that with the DX-7, a certain negative effect - likely coloration or boominess from close miking - was less pronounced than expected (HiFI-Stereo, May 1992, p.48). For the test, the speakers sat two feet from the side walls and two feet from the wall behind them. The microphone was on the forward axis of the left speaker, about twelve feet away (HiFI-Stereo, May 1992, pp.47-48).

Beyond this review, almost nothing is recorded. No specifications, dimensions, driver complement, price, or production years have surfaced. It appears to have been a loudspeaker model in Cerwin Vega's lineup during the early 1990s, but even that is inferred from the review date. The DX-7 does not appear in any of the broader Cerwin Vega documentation held in the Archive. It is a genuinely obscure model. Likely only a small number of units were produced, or it was overshadowed by more popular CV offerings of the era.
