  • Bass: Potent, chest-thumping, but not one-note. The 10" woofer is articulate enough for bass guitar lines.
  • Midrange: Slightly forward but not aggressive. Snare drums and vocals cut through a mix.
  • Highs: Smooth rolling-off above 15 kHz. Not for ultra-revealing studio monitoring, but fatigue-free for long listening sessions.
  • Dynamic Range: Excellent. These speakers come alive at moderate to high volumes. At low volumes, they lose some bass presence due to the port tuning (a common trait of vented designs).

The AT-40 is a three-way, bass-reflex floor-standing system designed for high efficiency and high output.

2. Legendary "Eyes" High-Frequency Driver A signature of the AT series, the AT-40 features Cerwin-Vega’s iconic dome tweeter, often referred to as the "Eyes" due to its distinct visual profile. This driver delivers crisp, room-filling high frequencies with a wide dispersion pattern, ensuring every seat in the house is the "sweet spot."

Driver Complement (The "Red" Heart)

  • Woofer: 1 x 10-inch (250mm) cast-frame woofer with CV foam surround (red)

    Woofer: The Legendary 10-Inch Power Plant

    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 high-excursion foam surround allows for significant cone travel without distortion.

    • Crossover frequencies: 500 Hz and 4.5 kHz.
    • Slope: 12 dB/octave (2nd order Linkwitz-Riley alignment).
    • Protection: Self-resetting polyswitch on tweeter circuit.
    • Components: Air-core inductors on tweeter, mylar capacitors.
