To contextualize the AT-40 specs, here is how it stacks against its siblings: cerwin vega at-40 specs
| Feature | Cerwin Vega AT-40 | Cerwin Vega AT-12 | Cerwin Vega AT-15 | | :--- | :--- | :--- | :--- | | Woofer | 10-inch | 12-inch | 15-inch | | Sensitivity | 94 dB | 96 dB | 101 dB | | Low End | 38 Hz | 35 Hz | 28 Hz | | Weight | 42 lbs | 58 lbs | 87 lbs | | Best For | Small rooms, nearfield | Medium rooms, rock music | Massive venues, parties |
The AT-40 is the "rational choice" for most homes. You get 90% of the AT-15’s slam without needing a forklift or a living room the size of a barn. | Specification | Detail | | :--- |
The AT-40 differs from budget CV models by including a dedicated midrange driver (many cheaper speakers use a woofer-tweeter two-way design). The 5.25" coated paper cone handles critical vocal and instrument frequencies from 500 Hz to 5 kHz, reducing intermodulation distortion.
The 1" soft-dome tweeter with ferrofluid cooling ensures smooth high-frequency extension without the harshness of cheaper metal-dome tweeters. Ferrofluid also improves power handling, preventing thermal compression during high-volume playback. | Parameter | Value | |-----------|-------| | Nominal
Takeaway: The AT-40 is surprisingly refined for a CV speaker. Vocals are clear, cymbals have sparkle but not sibilance, and the midrange isn't overly recessed.
The Cerwin Vega AT-40 specs paint a picture of a versatile, high-efficiency, bass-capable floorstander that excels at rock, pop, electronic, and home theater. They are not the most neutral or detailed speakers—audiophiles seeking flat frequency response should look elsewhere. But for raw dynamics, explosive transient response, and that "live concert" feel, the AT-40 delivers.
With a typical used market price of $150 to $300 per pair (plus re-foam costs), they are a fantastic value. Pair them with a 100W+ receiver, give them room to breathe, and you’ll understand why Cerwin Vega remains a legend.
Final note: Always verify Cerwin Vega AT-40 specs with the manufacturer’s original documentation if available. Production changes over the years (e.g., tweeter material or cabinet thickness) may result in minor deviations from the data presented here. Happy listening!
