Cerwin Vega — At40 Specs [patched]

The inclusion of an internal PTC protection device acts as a circuit breaker for the tweeter. If the speaker detects a dangerous power surge or clipping from an overdriven amplifier, the PTC temporarily cuts or resists the signal to prevent the voice coils from burning out.

Interestingly, many European-market AT-series speakers were built at the Dali factory in Denmark under an official license from Cerwin-Vega. While the drivers and crossovers were imported from the United States, the high-quality wood-veneer cabinets were constructed in Denmark, giving certain regional batches distinct structural craftsmanship.

For nearfield monitoring or detailed mixing work, the AT-40’s coloration—particularly bass emphasis and any mid-bass hump—means engineers should rely on reference checks on other, more neutral monitors or headphones. However, as consumer or multimedia speakers, they provide an engaging listening experience and deliver satisfying impact at lower amplifier powers due to relatively high sensitivity. cerwin vega at40 specs

features a classic three-driver layout designed for high-impact audio:

The Cerwin-Vega AT-40 is a 3-way loudspeaker system, meaning it splits the audio signal into three distinct frequency bands to be handled by dedicated drivers. Driver Complement The inclusion of an internal PTC protection device

Before we dive into the datasheet, context matters. The "AT" series stood for "Acoustically Tuned." This was Cerwin Vega’s mid-to-late 80s attempt to compete with brands like JBL, Klipsch, and Infinity in the "high-end consumer" space. Unlike the brutally simple CV speakers of the 70s, the AT series featured: While the drivers and crossovers were imported from

The Cerwin-Vega AT-40 is a vintage three-way bass reflex loudspeaker known for its high efficiency and signature "loud" sound profile. Introduced as part of the AT (Arc) series, these speakers were specifically designed to deliver high sound pressure levels with minimal amplifier power. Design: 3-way, Bass Reflex (ported) cabinet. Power Handling: 125 Watts. Frequency Response: 30 Hz – 22 kHz. Sensitivity: 95 dB (1 Watt @ 1 Meter). Nominal Impedance: 6 Ohms. Crossover Frequencies: 400 Hz and 3000 Hz.

Understanding the numbers above tells us a great deal about how the AT-40s are designed to perform.

strikes a perfect middle ground within the "Audio Theater" (AT) series. It delivers massive, floor-shaking sound pressure levels without requiring a high-end, high-wattage power amplifier. Cerwin-Vega AT-40 Core Specifications
