The AT-40 is often sought after by vintage audio collectors looking for a dynamic "party speaker" that can handle high volume levels without compression. Thanks to the 12-inch woofer and 94dB sensitivity, they are well-suited for rock, electronic, and hip-hop genres where bass impact is critical.
If you are thinking about buying a pair or working on a restoration, tell me: What do you plan to use with them? What is the condition of the foam surrounds on the woofers? What size room will you be putting them in?

strikes a perfect middle ground within the "Audio Theater" (AT) series. It delivers massive, floor-shaking sound pressure levels without requiring a high-end, high-wattage power amplifier. Cerwin-Vega AT-40 Core Specifications

The most important number on the AT-40’s spec sheet is its sensitivity: . To put this in perspective, an average bookshelf speaker produces about 87-89 dB with the same 1 watt of power. Because decibels are logarithmic, the AT-40 is roughly 4 to 5 times louder than a standard speaker at the same amplifier setting. This insane efficiency means that a modest 20-watt amplifier can drive the AT-40 to deafening levels, while a 200-watt amp can produce concert-hall pressure. The power handling is rated at 150 watts RMS (300 watts peak) . The combination of high sensitivity and high power handling creates a speaker with virtually unlimited headroom. 1210 (Red Foam Surround) | | Midrange | 4
