High-frequency driver with internal protection circuitry. Performance Review & Sound Profile
10-inch (25.4 cm) cast-frame or stamped-frame cone with a signature red polymer foam surround
The "AT" series (including the AT-40) is distinct from the more common "AT" (Acoustic Thunder) series from the late 1980s/early 1990s. The AT-40 is a later model (circa late 1990s to early 2000s), often considered part of the "Intensity" or transitional series, featuring a more modern, curved cabinet design while retaining Cerwin-Vega's signature high-efficiency, high-output philosophy. cerwin vega at40 specs
The midband frequencies (between 400 Hz and 3,000 Hz) are handled by a dedicated . Isolating the midrange prevents the large 10-inch woofer from muddying up critical acoustic territory, ensuring that vocals, guitars, and synthesizers cut through the mix with high clarity even at high playback volumes. 3. High-Frequency Tweeter (1-Inch)
The Cerwin-Vega AT40 is part of a larger family of loudspeakers, including the popular Cerwin-Vega XLS and SL series. Here's a brief comparison: High-frequency driver with internal protection circuitry
The is set at frequencies of approximately 800 Hz and 5,000 Hz. This carefully chosen dividing network ensures that the 12-inch woofer handles the deep bass and lower midrange (where cabinet resonance matters most), the 4-inch driver handles the critical vocal range, and the tweeter delivers only the highest harmonics and cymbal crash.
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. The midband frequencies (between 400 Hz and 3,000
Often overshadowed by its larger siblings (AT-60, AT-100, AT-15), the AT-40 represents a fascinating moment in hi-fi history—a bridge between the gritty, party-speaker reputation of CV and the refined "studio monitor" aspirations of the era. For collectors and budget vintage buyers, understanding the AT-40 specs is the key to unlocking a surprisingly versatile loudspeaker.
The following specifications are commonly cited for the AT-40 model: Specification Frequency Response 30 Hz – 22 kHz Power Handling 125 Watts (Peak/Maximum) Sensitivity (1W/1M) Nominal Impedance Crossover Frequencies 400 Hz and 3,000 Hz LF Driver (Woofer) 10-inch (ATW10) with fiber-impregnated cone Midrange Driver 5-inch cone HF Driver (Tweeter) 1-inch soft dome with ferrofluid and waveguide Protection
