For ADAM subwoofers, this means combining power and precision while simultaneously avoiding "impressive" bass volume at the cost of accuracy. Their task is it to complement the highly acclaimed lucidity and transparency of the ADAM monitors in the lower and lowest frequencies.All subwoofers up to the Sub2100 feature both balanced (XLR) and unbalanced (RCA) in and output connectors, and numerous controls to adapt to different room acoustics and requirements and a number of controls to adapt to different room acoustics and requirements.All units have a level control that varies from -60dB to +6dB, a phase ±180° switch and variable upper frequency barrier control (50-150Hz), a switchable 85Hz high pass filter for the satellite output. In addition, there is a 'signal-on/continuous' switch. This provides the option of automatic power up whenever the subwoofer receives a signal and automatic power off after 15 minutes of no signal.Sub10 Mk2The Sub10 Mk2 is a powerful subwoofer designed to extend the low frequency capabilities of any near or midfield monitoring and are ideal matches for ADAM monitors such as the AX- or the SX-Series.A large (2") voice coil is driven by a 200W Ice Power amp. This amp stays cool as it uses PWM technology in the amp and the power supply sections, producing > 90% overall efficiency, and can handle its maximum power without danger to the electronics or the driver. The Sub10 Mk2 houses an 10� woofer, capable of a frequency response of 25Hz - 150Hz. The larger Sub12 has a 12" woofer capable of producing a 3dB higher SPL max output and reproduces frequencies down to 22Hz.
