features a high-excursion woofer that delivers low-end down to 30 Hz. The cabinet features a rear-firing bass port to reinforce the kick-drum slam and deep bass frequencies common in rock, electronic, and hip-hop music.

: Like most Cerwin Vegas, the AT-40 excels in the low end. The 10-inch woofer (often featuring the iconic red/orange surround) provides a "chest-pounding" bass experience that is perfect for rock, hip-hop, and house music.
The is a vintage 3-way bass-reflex floorstanding speaker known for its high efficiency and powerful output, typical of the "Loud Speaker" legacy established by the brand. It is part of the AT (Advanced Technology) series, which is highly regarded for its robust power handling and suitability for loud listening environments. Technical Specifications

The AT-40 is a three-way, bass-reflex floor-standing system designed for high efficiency and high output. Specification 30 Hz – 22 kHz Power Handling 125 Watts (RMS) Sensitivity 95 dB (1W/1m) Impedance Crossover Points 400 Hz / 3,000 Hz Protection Self-resetting PTC (Positive Temperature Coefficient) Dimensions (HxWxD) Approx. 28.7" x 14.4" x 12.6" (730 x 365 x 320 mm) Key Features and Performance
: Typically consists of a dedicated woofer for low frequencies, a cone-based mid-range driver, and a tweeter for high frequencies. Key Performance Features High Efficiency : With a sensitivity of 95 dB, the
With a sensitivity rating often exceeding 98dB, the AT-40 is incredibly efficient. This means they require less amplifier power to reach cinema-level volumes compared to standard audiophile speakers. They are easy to drive for most AV receivers but truly shine when paired with high-current amplification. This link or copies made by others cannot be deleted
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.
Most modern bookshelf speakers average 85–87 dB sensitivity. That means to achieve the same volume as the AT-40, they need roughly 4 to 5 times more amplifier power.
