Cerwin Vega At-40 Specs
The Cerwin Vega AT-40 is a two-way, bi-amped loudspeaker that boasts an impressive set of specs. Here are some of its key features:
10-inch (25 cm) cast aluminum frame woofer with a 1.55-inch voice coil. Midrange: 5-inch cone midrange driver. Tweeter (High Frequency): 1-inch Mylar dome tweeter. Physical Dimensions & Build Dimensions: Approximately 28" H x 12.5" W x 11" D. Weight: Roughly 40 lbs (18 kg) per speaker.
However, because the impedance settles at , it draws slightly more current than a traditional 8-Ohm speaker. For optimum bass control and maximum headroom, pairing the AT-40 with a high-current solid-state amplifier or a robust vintage receiver from pioneers like Pioneer, Sansui, or Kenwood will yield the punchiest results. Maintenance and Modern Restoration

The visual hallmark of any classic Cerwin-Vega speaker is the striking red foam surround on the woofer. The AT-40 features a 10-inch low-frequency driver built on a rugged chassis. This woofer utilizes a lightweight, rigid paper cone optimized for fast transient response and high sound pressure levels (SPL). The cabinet's rear porting allows the 10-inch driver to drop down to a true 35 Hz, delivering deep, physical bass that you can feel in your chest. 2. Dedicated 5-Inch Midrange
While an original owner's manual is not available, this article compiles a comprehensive guide to the Cerwin Vega AT-40 specifications, drawn from multiple verified enthusiast sources.

The Cerwin Vega AT-40 is a testament to a unique era of speaker design, prioritizing efficiency, dynamic range, and sheer listening enjoyment over sterile accuracy. While they require a bit of care in terms of maintenance, their legendary durability and powerful sound continue to make them a highly sought-after speaker for those who love to rock out at home.
The midrange driver handles vocals and instruments, while the soft dome tweeter provides crisp, clear high frequencies that do not become fatiguing, even at high volumes. The high sensitivity of these drivers means the speaker doesn't need huge power to reach "concert" levels. 3. Crossover & Protection
: Most units include rear-mounted potentiometers for adjusting high and mid-range output to suit room acoustics.
Fortunately, because of the popularity of the AT series, exact-spec replacement foam kits are widely available. "Re-foaming" the 10-inch woofers is a straightforward DIY project that restores the speakers to their original factory performance. Additionally, checking the internal crossover capacitors and cleaning the rear attenuator dials with electronic contact cleaner will ensure these classic towers continue to perform for decades to come.
The Cerwin-Vega AT-40 occupies a particular corner of audio lore: part studio monitor, part home hi‑fi, and all about delivering punch where it counts. Whether you’re tracking in a small project studio, mixing electronic beats, or hunting for an affordable full-range speaker that refuses to hide the low end, the AT-40’s specifications tell a story about intentions and tradeoffs—one that helps you decide if it suits your needs.
: Crossover points split the signal at 400 Hz, sending crucial vocal and instrumental frequencies to a dedicated mid-range cone. This relieves the woofer from playing mid-tones, ensuring cleaner, more defined dialogue and presence.
