Cerwin Vega At-40 Specs -
The cabinets are solid, and the components are built to last, though the foam surrounds on the woofers may require replacement after 30+ years. Common Issues and Considerations (Buying Used) If you are buying a pair of , keep these factors in mind:
: 95 dB (1W/1m), allowing for high volume levels even with lower-powered amplifiers. Nominal Impedance : 6 Ohms. Crossover Points : 400 Hz and 3,000 Hz.
Looking at the in 2025, they tell a story of a speaker that was ahead of its time in efficiency but rooted in classic, dynamic sound. Modern $500 speakers may have flatter frequency response, but none will produce that chest-thumping 38 Hz bass with only 10 watts of power. cerwin vega at-40 specs
The AT-40 is engineered as a high-performance, passive full-range speaker. Its primary technical details include: 30 Hz to 22 kHz. Power Handling: 125 Watts (RMS). Sensitivity: 95 dB (measured at 1 Watt @ 1 Meter). Nominal Impedance: 6 Ohms. Crossover Points: 400 Hz and 3000 Hz.
However, because the impedance settles at , it draws slightly more current than a traditional 8-Ohm speaker. For optimum bass control and maximum headroom, pairing the AT-40 with a high-current solid-state amplifier or a robust vintage receiver from pioneers like Pioneer, Sansui, or Kenwood will yield the punchiest results. Maintenance and Modern Restoration The cabinets are solid, and the components are

for the European market, using American-made drivers and crossovers housed in high-quality European cabinets. They became the go-to choice for garage jams and house parties, known for being so efficient that even a modest receiver could drive them to window-rattling levels. Technical Specifications The AT-40 is a 3-way bass reflex Crossover Points : 400 Hz and 3,000 Hz
The is a vintage 3-way floor-standing speaker known for its high efficiency and massive output, often described as a "party speaker" capable of reaching high sound pressure levels with minimal power. While specific detailed brochures for the AT-40 model specifically are rarer than its larger siblings (like the AT-80 or AT-100), it follows the standard design of the AT series introduced in the late 1980s. Technical Specifications
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.
excels with rock, EDM, hip-hop, and movies. They deliver a physical, energetic sound.
