The AT-40's acoustic performance is characterized by its clear, detailed highs and tight, controlled lows. The speaker's 12-inch woofers provide a robust low-end response, while the 1.5-inch high-frequency driver delivers crisp, accurate treble. The AT-40's frequency response is remarkably flat, with a deviation of only ±3 dB from 50 Hz to 15 kHz. cerwin vega at-40 specs
Unlike modern "audiophile" speakers that require hundreds of watts to produce moderate volume, the AT-40 was built for high efficiency. You could drive these to ear-bleeding levels with a modest 35-watt receiver.
Handling everything above 3,000 Hz, the dome tweeter provides crisp, bright highs. It is protected by an internal PTC (Positive Temperature Coefficient) device. If the speakers are pushed too hard and the tweeter begins to overheat, the PTC temporarily drops the signal to protect the voice coil from blowing, automatically resetting once it cools down.

The 10" woofer is the heart of the AT-40. Unlike the massive 12" or 15" drivers found in AT-15 or AT-12 models, the 10" unit offers a compromise: tighter, faster bass with less boominess, while still able to move substantial air. The cast-frame basket reduces resonance, and the allows for significant cone travel without distortion.
The influences placement. Unlike front-ported speakers, the AT-40 needs some space behind it (at least 6-12 inches) to allow the port to breathe. Placing them flush against a wall will artificially boost bass but may cause muddiness or "chuffing" noise.
