[extra Quality] — Cerwin Vega At-40 Specs

When discussing the golden era of high-efficiency home audio, few names command as much respect—and nostalgic reverence—as . Known for their signature orange surrounds, aggressive styling, and earth-shaking bass response, Cerwin Vega speakers have been the party animal’s choice for decades. Among their storied lineup sits the Cerwin Vega AT-40 , a floor-standing tower that often flies under the radar compared to its larger siblings (like the AT-15 or D-9), yet delivers a potent blend of power handling, sensitivity, and classic CV character.

The is a high-efficiency, floor-standing loudspeaker produced during the late 1980s to early 1990s as part of the brand’s “AT” (Acoustic Technology) series. Known for their distinct orange surrounds and high sensitivity, Cerwin-Vega speakers have long been associated with professional sound reinforcement and home high-output hi-fi systems. The AT-40 models specifically target users seeking high dynamic range, low distortion at high volumes, and extended low-frequency response without requiring massive amplification.

: 3-way system, typically featuring a 10-inch woofer (ATW10 for European models).

: By splitting the audio across a dedicated woofer, mid-range driver, and tweeter, the AT-40 manages a fuller soundstage than smaller two-way bookshelf speakers of the same era. cerwin vega at-40 specs

: Thanks to the 30 Hz extension, the bass kickdrums and bass lines are felt as much as they are heard. The low end is full, robust, and punchy, carrying excellent acoustic headroom.

The core appeal of the Cerwin-Vega AT-40 lies in its impressive electrical efficiency and massive headroom. Unlike modern low-sensitivity bookshelf speakers that require high-current amplifiers, the AT-40 can reach party-level volumes with a modest power source. 📊 Technical Spec Sheet Specification 3-Way Bass Reflex (Ported Enclosure) Frequency Response 30 Hz – 22 kHz Power Handling Capacity 125 Watts (Continuous RMS) Sensitivity (1W @ 1M) Nominal Impedance Crossover Frequencies 400 Hz / 3,000 Hz High Frequency Protection PTC (Positive Temperature Coefficient) Automatic Reset Cabinet Dimensions (H x W x D) 730 mm x 365 mm x 320 mm (approx. 28.7" x 14.3" x 12.6") Drivers and Acoustic Architecture

. It is characterized by the classic Cerwin-Vega "loud and punchy" sound, featuring the iconic red-surround woofer. Technical Specifications Speaker Type 3-way, Bass Reflex (Ported) Frequency Response 30 Hz – 22 kHz Power Handling 125 Watts (RMS/Continuous) Sensitivity 95 dB (1W @ 1m) Nominal Impedance Crossover Frequencies 400 Hz and 3,000 Hz Protection Self-resetting PTC (Tweeter protection) Dimensions (H x W x D) 730 x 365 x 320 mm (~28.7" x 14.4" x 12.6") Key Characteristics Driver Configuration : 3-way system, typically featuring a 10-inch woofer

The table below aggregates the most consistent and reliable technical data for the Cerwin Vega AT-40.

Most modern bookshelf speakers average 85–87 dB sensitivity. That means to achieve the same volume as the AT-40, they need roughly 4 to 5 times more amplifier power.
