Adam Audio Sub12 12-Inch Powered Studio Subwoofer

The Adam Audio Sub12 12-inch powered studio subwoofer is a professional studio subwoofer designed to partner with ADAM Audio’s S Series and A Series midfield monitors, delivering precise, accurate bass extension down to 22Hz through a 12-inch extended-cone-travel woofer with a 2-inch voice coil, driven by a 200W RMS / 300W Music PWM power amplifier. As a result, engineers working in medium to large control rooms gain the low-frequency foundation needed for confident bass and sub-bass decisions in demanding mixing and mastering sessions, with a maximum undistorted SPL of 115dB at one metre providing ample headroom for professional monitoring levels. A continuously variable crossover from 50Hz to 150Hz allows precise integration with any satellite monitor combination, while a switchable 85Hz high-pass filter on the satellite output protects connected monitors from bass frequencies they cannot reproduce cleanly. In addition, a 180-degree phase switch, level control from -60dB to +6dB, and both balanced XLR and unbalanced RCA inputs and outputs give engineers complete flexibility in system integration and calibration. Marshall Music South Africa stocks the Adam Audio Sub12 12-inch powered studio subwoofer for South African professional studios looking to extend their S Series or A Series monitoring system with accurate, high-output bass reproduction.

Professional Bass Extension From the Adam Audio Sub12 12-Inch Powered Studio Subwoofer

Whether you’re partnering the Sub12 with a pair of S3V midfield monitors for a full-range system or adding low-frequency extension to an A Series nearfield setup, the Adam Audio Sub12 12-inch powered studio subwoofer integrates cleanly and performs with the precision engineers demand at the professional level. The 12-inch extended-cone-travel woofer’s long excursion design delivers deep, tight bass reproduction at high SPLs without the compression and distortion associated with conventional woofer designs. The downward-firing bass reflex port is generously sized with rounded edges to eliminate port chuffing noise, keeping the Sub12’s output clean and artefact-free across all operating levels. However, the Sub12’s defining practical strength is its system-level flexibility — variable crossover, phase control, high-pass satellite filter, and full XLR I/O make it straightforward to integrate into any professional monitoring chain and calibrate to the room. Marshall Music South Africa recommends the Adam Audio Sub12 12-inch powered studio subwoofer to South African engineers and studios who need professional-grade bass extension to complete a mid-to-large format reference monitoring system.

Adam Audio

Adam Audio (Advanced Dynamic Audio Monitors) is a Berlin-based professional studio monitor manufacturer founded in 1999, built around a single defining technology: the proprietary X-ART (Accelerated Ribbon Technology) tweeter. Inspired by Oskar Heil’s 1960s Air Motion Transformer invention, ADAM Audio’s ART tweeter accelerates air four to five times faster than conventional dome tweeters, delivering an exceptionally detailed and accurate high-frequency response that quickly earned the brand a devoted following among recording engineers, mixers, and mastering professionals worldwide. The game-changing ADAM Audio S3A monitor brought the brand to global prominence in the early 2000s, establishing the S Series as the flagship reference line and cementing ADAM Audio’s reputation for precision and transparency at the highest level of professional monitoring. Today the brand offers four distinct monitor ranges to suit every studio environment and budget — the T Series for entry-level professional use, the A Series with DSP-equipped mid-range monitors, the flagship S Series reference monitors in horizontal and vertical configurations, and the D Series for desktop production setups — all complemented by a range of professional subwoofers. Acquired by the Focusrite Group in 2019, ADAM Audio continues to design and manufacture in Berlin, maintaining the rigorous engineering standards and acoustic precision that have made it one of the most trusted monitor brands in professional audio.
