is a 3-way bass reflex system that balances Cerwin-Vega's signature deep bass with a more refined high-frequency response than earlier "D" series models. Frequency Response: 30 Hz – 22 kHz. Power Handling: 125 Watts (Continuous/RMS). Sensitivity: 95 dB (1 Watt @ 1 Meter). Nominal Impedance: 6 Ohms. Crossover Frequencies: 400 Hz and 3000 Hz.

Protection: Equipped with a PTC (Positive Temperature Coefficient) self-resetting circuit protector for the tweeter. Driver Configuration

features a classic three-driver layout designed for high-impact audio:

Low Frequency (Woofer): 10-inch high-excursion driver with a cast aluminum frame. European versions, often built under license at the Dali factory in Denmark, typically utilized the ATW10 woofer.

Mid Frequency: 5-inch cone driver optimized for vocal clarity and midrange presence.

High Frequency: 1-inch microcell polymer dome tweeter. This represented a departure from traditional horn-loaded tweeters, offering a smoother, less "shouty" high-end. Design and Build cerwin vega at40 specs
