Cerwin-Vega AT-40 Specs: A Detailed Guide to the Classic Loudspeaker
One of the best features of the AT-40 is the inclusion of adjustable high-frequency and mid-frequency potentiometers (dials) on the rear terminal plate. These dials allow you to manually boost or cut the output of the tweeter and midrange driver to match your room acoustics or personal taste. Additionally, these speakers feature built-in circuit breaker protection to safeguard the delicate drivers from accidental power surges or amplifier clipping.

The "AT" stands for "Atlas," and the build quality matches the name. The woofer features a cast-aluminum frame (rather than stamped metal), which is more rigid and resonance-resistant. Combined with a rugged cabinet design, this allows the speaker to handle high power (200 watts RMS / 400 watts peak) without distortion or mechanical failure.
These floor-standing speakers are known for their high efficiency, "rock-and-roll" dynamics, and the iconic red-framed woofers. Physical Build & Dimensions Cerwin-Vega AT-40 Specs: A
Lab tests from the era (courtesy of Audio Magazine , Nov 1989) showed the AT-40 had a slight rise around 70Hz (+2 dB) due to the port tuning, then a remarkably flat midrange (±2 dB from 300Hz–3kHz), followed by a 3-4 dB roll-off above 15kHz. This makes them "warm and forward," not harsh.

In conclusion, the Cerwin Vega AT-40 is not a studio monitor; it is a statement of intent. The specifications tell a story of raw efficiency, massive displacement, and rugged construction. If your goal is to feel the kick drum in your ribcage, to fill a large living room with sound without buying a separate subwoofer, or to simply own a piece of high-efficiency history, the AT-40’s specs are a blueprint for success. They are the technical manifestation of Cerwin Vega’s motto: “Live… Loud.”
Takes over at 400 Hz and extends up to 3,000 Hz. This dedicated mid-range ensures that vocals and instruments retain distinct separation from the heavy bass frequencies generated by the woofer. 3.
