Cerwin Vega At-40 Specs Verified

Bass-reflex (vented) design to maximize efficiency and bass extension. Physical Dimensions: 730 mm (H) x 365 mm (W) x 320 mm (D).

The high frequencies are managed by a 1-inch polymer dome tweeter that extends up to 22 kHz. Cerwin-Vega acoustic engineers recognized that these speakers would be pushed to their absolute limits at parties and high-volume listening sessions. To prevent accidental burnouts, the AT-40 includes a rear-panel protection fuse for the tweeter circuit. If the amplifier starts clipping or sending dangerous spikes, the fuse blows first, saving the voice coil from permanent damage. 4. Acoustic Level Controls

The is a classic three-way, bass-reflex floor-standing speaker known for delivering the "legendary CV sound"—high efficiency and high output . Often associated with the 1980s and early 90s, the AT (Acoustic Transformer) series was designed to provide room-shaking bass and high sound pressure levels with relatively modest power requirements. Core Technical Specifications cerwin vega at-40 specs

High efficiency, often above 95 dB (1w/1m), meaning they play loudly with lower power amplifiers.

: PTC (Positive Temperature Coefficient) high-frequency protection to prevent tweeter damage. Dimensions : Key Characteristics Bass-reflex (vented) design to maximize efficiency and bass

One of the most impressive specifications of the Cerwin-Vega AT-40 is its . In practical terms, this means the speaker can produce a very loud 97 decibels of sound with just 1 watt of power measured at a distance of one meter. Because they are so efficient, you do not need a massive, high-end amplifier to drive them. Even a modest 35-watt vintage receiver or a modern budget amplifier can drive the AT-40 to room-shaking volumes without breaking a sweat. Sonic Signature

The AT-40 is efficient, designed to deliver high sound pressure levels (SPL) without requiring massive power amplifiers. Sonic Signature The AT-40 is efficient
