The Cerwin-Vega! AT-40 is a studio monitor and consumer loudspeaker model from Cerwin-Vega, a brand long associated with high-efficiency, bass-forward loudspeakers designed originally for live sound and car audio before moving into home and studio markets. The AT-40 exemplifies the company’s design priorities—robust low-frequency response, high sensitivity, and a focus on musical impact—while reflecting trade-offs common to many speakers that emphasize bass and loudness.
Like its siblings, it features the iconic red-ringed woofer and a bass-reflex cabinet designed to "move the air". cerwin vega at40 specs
