ADAM Audio Sub12 2-Way Active Subwoofer - Single

Two-way active bass reflex speaker featuring powerful, compression-free sound reproduction even at very high sound levels
MFR# Sub 12

Product Description

The Adam Audio Sub12 is powerful 12-inch subwoofer designed for use with near or midfield monitoring systems. With a sturdy woofer, an extended cone, and a rugged voice coil, Sub12 subwoofers offer an extended frequency response down to 22 Hz. Equipped with a 300 W PWM amplifier, Sub12 is so loud you’ll swear the kick drum is actually kicking you in the chest.


Fill out the frequency response of your favorite near or midfield monitors with Sub12. Capable of delivering a linear frequency response down to 22 Hz, Sub12 subwoofers allow you to accurately make critical mix decisions in the sub bass frequencies. Sub12 subwoofers utilize a down-firing bass reflex tube to avoid unwanted ventilation noise.

Equipped with a high-efficiency PWM amplifier that produces over 90% efficiency, Sub12 subwoofers can be used for hours on end without fear of overheating. Capable of delivering powerful, distortion-free sound at levels up to 115 dB SPL, Sub12 packs a powerful punch. A special 12-inch woofer with a paper diaphragm helps prevent ear fatigue during long listening sessions.


Sub12 subwoofers can be customized to suit any studio. Quickly toggle Sub12 on or off with an optional foot switch to A/B your mix without taking your hands off the keyboard. Fine-tune your monitoring system with a selectable crossover frequency. Create a double bass array with the additional sub output. Or high-pass satellite speaker outputs for an optimal film mixing setup.


With analog XLR and RCA input, Sub12 subwoofers offer balanced and unbalanced connections for use in professional and home theater settings. And with a small, compact frame, they fit neatly in any mixing environment. Adam Audio Sub12 subwoofers come with a two-year manufacturer’s warranty, which can be extended to five years with registration.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
