Adam Audio Sub15 15.5-Inch Powered Studio Subwoofer

The Adam Audio Sub15 15.5-inch powered studio subwoofer is a high-power professional studio subwoofer designed for large control rooms and demanding monitoring applications, housing a 15-inch aluminum-membrane woofer driven by twin magnets and a 100mm voice coil, powered by a 1,000W RMS PWM amplifier with near 90% efficiency for deep, clean bass extension down to 20Hz. As a result, engineers working in large rooms with S Series main monitors or full-range monitoring systems gain a subwoofer with the driver surface area and amplifier power to fill the space with accurate, controlled low-frequency reproduction at professional SPLs — achieving a maximum output of 120dB at one metre without compression or distortion. The 15-inch aluminum membrane driver’s combination of stiffness, low mass, and twin-magnet drive system enables linear excursion and precise bass reproduction at high output levels that would cause conventional woofer materials to compress and colour the sound. In addition, a continuously variable crossover from 50Hz to 150Hz, level control from -60dB to +6dB, a phase reverse switch, and balanced XLR and unbalanced RCA inputs and outputs provide complete system integration flexibility. Marshall Music South Africa stocks the Adam Audio Sub15 15.5-inch powered studio subwoofer for South African professional studios and mastering facilities who need a high-power subwoofer to complete a large-format reference monitoring system.

High-Power Performance From the Adam Audio Sub15 15.5-Inch Powered Studio Subwoofer

Whether you’re extending the low-frequency reach of a pair of S5V main monitors in a large room or building a full-range monitoring system for film dubbing and immersive audio work, the Adam Audio Sub15 15.5-inch powered studio subwoofer provides the power and precision required at the highest level. The 1,000W PWM amplifier’s near 90% efficiency keeps operating temperatures low even during extended high-output sessions, ensuring consistent performance through long mixing and mastering days. The downward-firing bass port, designed with ample dimensions and rounded edges, eliminates port turbulence noise that would otherwise colour the sub-bass reproduction and compromise mixing accuracy. Marshall Music South Africa recommends the Adam Audio Sub15 15.5-inch powered studio subwoofer to South African professional studios, mastering engineers, and post-production facilities who need a powerful, accurate subwoofer as the foundation of a 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.
