The ADAM Sub7 is a 7″, 140W/210W subwoofer with remote control, designed for use in small studios, mobile rigs, or home theater
One of the worst-kept secrets in the physics of sound reproduction is that small drivers under six inches have difficulty with low frequencies, and require help—usually in the form of bass reflex ports or a subwoofer. However, it would be disproportionate to add a big 1000W sub to a system comprised of small monitors, such the ADAM A5, A7, or those in the AX series, for which ADAM built the Sub7 to be a perfect match. The Sub7 features a 7″ driver and 140W RMS amplifier in a small cabinet that fits easily where studio real estate is in limited supply. It cranks out a punchy, powerful bass down to 32Hz that is both accurate and realistic. To make adjustments without having to leave your sweet spot (or sofa if you’re using the Sub7 for a home theater), ADAM Audio has bestowed the Sub7 with a wireless remote control that allow you to control input level and crossover.
ADAM Sub7 subwoofer in one take:
- 7″ Subwoofer (paper)
- Amplifier Power RMS / Music: 140 W / 210 W
- Frequency Response: 32 Hz – 150 Hz
- Max. peak SPL at 1 m: ≥107 dB
- Wireless remote Control
ADAM low-frequency driver
With accuracy being the order of the day, ADAM designed a special woofer for the Sub7 that features extended cone travel and a heavy-duty coil, optimized for a bass reflex enclosure. The Sub8 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 Sub7 subwoofer provides a precise combination of low cutoff frequency (-3dB at 32Hz) and undistorted high SPL (107dB at 1m).
Efficient PWM amplifier
The Sub7 is equipped with a PWM, or class D amplifier. Instead of linear power regulation used in Class A/B amplifiers, which leads to energy losses in power transistors, Class D amplifiers use switching transistors. Nearly no energy loss occurs at the transistor and nearly all the power is carried to the transducer. This amplifier produces over 90% efficiency and can handle critical passages without overheating for long periods of time.
Controls and I/O
The Sub7’s front baffle features two motorized knobs for input level and crossover frequency settings. These controls can be used either manually or via the included wireless remote, allowing you to optimize sound reproduction from your listening position.
On the rear-panel are balanced XLR and unbalanced RCA input connectors. The Sub7 also has left and right satellite outputs that connect to the inputs of the left and right main powered speakers or the inputs of the amps powering the main speakers. The satellites can be driven full range or with a 85Hz high pass. There is also a phase reversal switch in case the satellites are out of phase with the subwoofer.
