ADAM Audio's Sub15 Subwoofer

Get to know them!

Designed for midsized and larger control rooms, the ADAM Audio Sub15 is an extremely powerful subwoofer that extends the low-frequency range of any midfield or main monitors down to 20Hz. The Sub15 houses a robust 15" aluminum-diaphragm woofer with two massive magnets and a 4" voice coil driven by a high-efficiency 1000W PWM power amplifier which combines low heat generation with high performance to handle maximum power levels during lengthy sessions. The rear panel is fitted with two knobs that let you tweak the input level and crossover frequency settings to optimize your monitor setup from your preferred listening position. Satellite speakers can be driven either full range or highpass filtered at 85Hz. An XLR sub output lets you cascade additional subwoofers as required for any monitoring setup.

Breathtaking bass response down to 20Hz

If you've ever heard a loud playback on the main monitors in a world-class studio, it's a revelation. For the uninitiated, the first reaction is one of being overwhelmed. After you've caught your breath, the first thing you marvel at is the incredibly tight and deep bass. With the Sub15's linear frequency response extending down to 20Hz, you feel in your chest cavity the crush of a well-recorded kick drum, the full weight of organ pedal tones or a fat unison synth bass. To record frequencies this low, you need to be able to hear them. With the ADAM Audio Sub15, you can.

ADAM Audio: elevating the state of the art

From its 1999 launch in Berlin, ADAM Audio has built a solid reputation among the pro audio cognoscente. Sweetwater knows that a superior speaker system has superior components, and this is one area where the company has a distinct edge. With years of R&D behind each proprietary driver, ADAM Audio's custom driver technology expresses itself in breakthroughs such as their X-ART (eXtended Accelerating Ribbon Technology) tweeter, which is based on a groundbreaking 1960s invention, the Heil Air Motion Transformer — and in fact, was the main impetus for the formation of ADAM Audio. The X-ART tweeter became the key to ADAM's signature transparent, high-definition sound; and the core development of ADAM’s proprietary designs going forward.

Embracing, exploiting, and working with modern materials has allowed ADAM Audio to formulate loudspeaker components that continually elevate the state of the art in studio monitor design. Materials such as rare-earth magnets and high-strength diaphragm foils have increased reliability, enhanced performance, and made possible new driver geometry. As compared with conventional driver technology, Adam drivers deliver optimized radiation characteristics, lower distortion, and higher efficiency. Along with installations in a growing number of top studios, ADAM Audio's monitor range has garnered rave reviews from audio experts and recording engineers worldwide. If you're considering an upgrade to world-class monitoring, you'll be in good company with ADAM Audio monitors.
