Specs | Cerwin Vega At40

Before jumping into the raw data, it helps to understand what the Cerwin Vega AT-40 represents. The AT series (which stands for "Active Tuned") was introduced by Cerwin Vega around 1989. In the late 1980s, the audio world was shifting, and Cerwin Vega, a company known for its high-efficiency, hard-hitting speakers, aimed to blend its legendary output with more modern design elements and improved sound quality.

With a sensitivity of 95 dB, these speakers can produce high volume levels even with relatively low-powered amplifiers, making them a popular choice for rock and popular music. Cabinet Build:

Since the AT-40 has been discontinued for many years, its value is determined by the second-hand market. Forum posts from the mid-2000s mention prices around 1500 SEK (approximately $150 USD at the time) for a pair in "top condition". Today, prices vary greatly based on condition, whether the woofers have been refoamed, and the local market. A well-maintained pair can often command higher prices, reflecting their growing status as a sought-after vintage classic. cerwin vega at40 specs
