The heart of the AT-40 is its 10-inch woofer. Cerwin-Vega utilized a custom-designed cone suspended by their signature red foam surround. This driver is housed in a sturdy basket assembly, allowing for high excursion (physical movement) without warping. Because it operates in a tuned, rear-ported bass reflex cabinet, this woofer can effortlessly drop down to 35 Hz, delivering physical, punchy bass that you can feel in your chest. 2.

The original red foam surrounds deteriorate over time due to humidity and UV exposure. If the red foam looks crumbly, torn, or is missing entirely, the woofers will need to be re-foamed. Luckily, re-foam kits are inexpensive ($20–$30) and a popular DIY project.
Cerwin-Vega AT-40 is a classic three-way floorstanding speaker known for delivering the "loud and proud" sound that defined the brand's legacy during the late 1980s and early 1990s. Often built under license at the Dali factory in Denmark
