Avid 330

Little is documented about the Avid 330. What the record shows comes from brief mentions in period audio publications. The 330 was a three-way loudspeaker, part of Avid's line during the late-seventies. High Fidelity (March 1979, p.49) noted that the design philosophy behind Avid's speakers - controlled directivity and uniform omnidirectional response - was "discernible in the Model 330." A later listing in the same magazine (1980, p.147) gave the basic driver complement and frequency response.

Known specifications drawn from that period review:

Drivers: 10″ woofer, 1½″ soft‑dome midrange, 1″ soft‑dome tweeter
Frequency response: 39 Hz–20 kHz ±3 dB (re 90 dB SPL)
Anechoic response (from the same review series) within ±2½ dB from 50 Hz to 40 kHz, with a gradual roll‑off above 2 kHz typical of the model’s design.

No further details on dimensions, impedance, crossover points, or original pricing have surfaced. The 330 appears to have been a well-regarded but not heavily documented model in Avid's lineup during the late-seventies.
