Cerwin Vega At40 Specs ((free)) Now
When audiophiles mention Cerwin Vega, the immediate mental image is usually of the massive, high-efficiency "CLSC" series (like the CLS-215) or the legendary, earth-shaking "Earthquake" subwoofers. However, tucked neatly into the late 1980s and early 1990s catalog is a sleeper hit: the .
Here is why this feature stands out:
The AT-40 is a 3-way, bass-reflex floor-standing loudspeaker. It is the smaller sibling to the AT-60, but unlike the AT-60 which sometimes struggled with midrange muddiness, the AT-40 is praised for a surprisingly balanced sound for its size—provided you feed it enough clean power. cerwin vega at40 specs

A common flaw in large vintage speakers is "muddy" midrange caused by the massive back-wave air pressure of the woofer interfering with the smaller midrange cone. Cerwin-Vega solved this in the AT-40 by placing the 5-inch midrange driver into an internally sealed sub-chamber. This ensures that vocals and acoustic instruments remain clean, distinct, and free from intermodulation distortion. 3. The Metallized Mylar Tweeter When audiophiles mention Cerwin Vega, the immediate mental
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.
For enthusiasts looking to restore these, high-quality re-foaming kits are widely available through retailers like Simply Speakers or The Speaker Exchange , as the original foam surrounds tend to degrade after 20–30 years.
