The ADAM Sub12 is a 200/300-watt subwoofer with a special 12″ driver with extended cone travel and heavy-duty coil optimized for accurate reproduction

The ADAM Sub12 is a powerful subwoofer for systems in medium-sized control rooms that is both a precision tool for mixing as well as a source of listening enjoyment. With meticulous attention to detail and the innovative technical acumen that ADAM is known for, the Sub12 accurately produces bass down to 22Hz with all the sound a fury you’d expect from a sub with a maximum SPL peak of 115dB at one meter. Built to add quality sub bass to any monitor system, the Sub12 is the perfect complement to ADAM’s AX or SX series monitors in 2.1 or 5.1 configurations.

ADAM Sub 12 powered subwoofer in one take:

  • 12″ subwoofer (paper)
  • Amplifier power RMS/Music: 200W/300W
  • Frequency response: 22Hz – 150Hz
  • peak SPL at 1 m: ≥115dB

ADAM low-frequency driver

With accuracy being the order of the day, ADAM designed a special woofer for the Sub12 that features extended cone travel and a heavy-duty coil, optimized for a bass reflex enclosure. The Sub12 has a front-firing woofer with a down-firing bass reflex tube to avoid intrusive ventilation noise because of its large size and shape. The Sub12 subwoofer provides a precise combination of low cutoff frequency (-3dB at 22Hz) and undistorted high SPL (115dB at 1m).

Efficient PWM amplifier

The PWM amplifier produces over 90% efficiency and can handle critical passages without overheating for long periods of time. An additional output allows you to cascade as many subwoofers as needed.

Controls and I/O

The left and right line-level signal from your audio source can be connected to either the left/right balanced XLR inputs or unbalanced RCA inputs. The Sub12 has Left and Right Satellite Out jacks which connect to the inputs of the left and right main powered speakers or power amps for the main speakers. The Sub12 has a phase switch that enables you correct phase in relation to the mains. The rear panel also has a balanced XLR sub out that mirrors the input signal, which allows you to daisy chain as many Sub12s as you need. The Sub Level control lets you control the volume of all the subs at once. The satellites can be driven full range or with a 85Hz high pass.

The Sub12 controls includes Sub Level, which controls the Input Sensitivity from -60dB to +6dB. It also has a Sub Filter control that adjusts the upper frequency limit, which is variable between 50Hz to 150Hz

 The Sub12 is a powerful subwoofer designed to accurately extend the low-frequency capabilities of any near- or midfield monitoring system down to 22Hz. To incorporate an ADAM Sub12 into your system, call or chat online with your Westlake Pro Sales Consultant today.
