PTC (Positive Temperature Coefficient) tweeter protection circuit.

The heart of the AT‑40 is a 10‑inch woofer with the company’s signature red foam surround. This lightweight cone is designed for fast transient response and high mechanical stability, allowing it to move a large volume of air with minimal distortion. The red foam surround not only looks distinctive but also provides the flexibility needed for long excursion, which contributes to the deep, punchy bass that Cerwin‑Vega is famous for. To accommodate the woofer’s travel, the cabinet is built as a , with a rear‑firing port that reinforces low frequencies and reduces air turbulence at high output levels.

The complete specifications, performance capabilities, and design architecture of the Cerwin-Vega AT-40 provide a detailed look at what makes this speaker unique. Technical Specifications

The internal crossover network splits signals at and 3000 Hz using clean slopes to manage driver transitions smoothly. To protect the voice coils from damage during heavy parties or accidental clipping, Cerwin-Vega integrated an internal PTC (Positive Temperature Coefficient) protection circuit . If the tweeter gets too hot from excessive power, the PTC safely restricts current until temperatures drop, acting as an automatic fuse. 3. Bass-Reflex Enclosure Construction The Legendary Cerwin-Vega AT-40: Compact Powerhouse Specs If

The heart of the AT-40 is its 10-inch woofer. Cerwin-Vega utilized custom-wound voice coils and massive magnet structures to ensure the cone could move large volumes of air without distorting. The iconic red-orange foam surround is made of a compliant polymer designed to allow maximum excursion. This driver handles everything from 30 Hz up to the first crossover point at 400 Hz, giving the speaker its characteristic punchy, physical bass response. The Midrange Driver

Like many vintage Cerwin Vega models, the woofer surrounds are made of foam which can deteriorate over time. If the bass sounds distorted or the foam looks cracked, you may need a , which is a common and straightforward repair for these units. Learn about Cerwin-Vega's legacy of high-quality audio
