Cerwin Vega At40 Specs Link

The Cerwin-Vega AT-40 is a vintage floor-standing loudspeaker from the celebrated AT (Advanced Technology) series, produced during the late 1980s and early 1990s. Known for their high efficiency and "rock and roll" sound signature, these speakers were designed to deliver high sound pressure levels with minimal amplifier power. Core Technical Specifications

With a 95 dB sensitivity rating, these speakers can reach high volumes even when paired with relatively modest amplifiers. Signature Sound: cerwin vega at40 specs

Moving to the midrange, the AT-40 employs a 4-inch cone driver, rather than a dome. This design choice prioritizes dynamic range and power handling over ultimate transparency. The midrange cone is typically treated paper or polypropylene, chosen for its natural damping properties. High frequencies are handled by a 1-inch phenolic dome tweeter. While modern soft-dome tweeters offer sweeter highs, the phenolic dome is legendary for its ruggedness; it can handle significant power without distortion and is highly resistant to being blown out at high volumes.

The Heart of the Beast: Driver Configuration

The AT-40 is a three-way, bass-reflex design, a configuration Cerwin Vega has long mastered. The specifications begin with the low-frequency driver: a 12-inch cast-frame woofer. Unlike cheaper stamped steel frames, the cast frame ensures rigidity, reducing unwanted resonances at high volumes. This woofer features the iconic Cerwin Vega "red surround"—a treated foam or cloth roll that is notably more durable and compliant than standard foam, allowing for the extreme cone excursion required to produce the brand's signature "heart-thumping" bass. The spec sheet lists the woofer's impedance at 8 ohms (nominal), making the AT-40 an easy load for most receivers and amplifiers. High frequencies are handled by a 1-inch phenolic
