Our subwoofers are dedicated to ADAM Audio's primary goal: the best possible authenticity in the reproduction of music. For our 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.
"I recommend it highly to anyone looking for a top-notch subwoofer." Tape Op on the Sub12 (Feb/March 2009)
All subwoofers up to the Sub2100 feature 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.
The Sub20 and Sub24 are very powerful subwoofers designed for medium sized or larger control rooms in which powerful and yet accurate extra deep bass monitoring is required.
The Sub20 is equipped with two long throw 10" drivers which are meant to reproduce LFE or other low frequency signals down to 25Hz. The Sub24, housing two long throw 12" drivers, extends down to 22Hz.
The power of two subwoofers
The Sub20 and Sub24 each have two drivers, which are mounted in chambers at opposite sides of the cabinet. Due to this alignment, the forces applied to the cabinet oppose each other and consequently compensate themselves, so that the cabinet stays much quieter than with conventional arrays. Distortion is drastically reduced in this manner, resulting in improved signal clarity, especially at higher levels.
There are two down firing bass reflex tubes that, because of their size and construction, successfully avoid ventilation noise.
The amplifier section has two units, each capable of delivering 200W continuous or 300W peak power to their corresponding drive units. Both power supply and amplifier section use PWM technology, meaning very high efficiency (≥90%) and cool operation in even the most critical phases of operation.
An additional output allows daisy-chaining as many Sub20s / Sub24s as desired.
