Adam Audio Sub15

ADAM Audio Sub15 is a high-power active studio subwoofer for medium to large control rooms and professional stereo or multichannel systems, featuring a 15.5” aluminum woofer, 1000W RMS/1200W music PWM amplification, a frequency response from 20Hz to 150Hz, a maximum SPL of at least 120dB at 1 meter, a down-firing bass reflex design, an adjustable 50-150Hz crossover, an 85Hz satellite filter, 0°/180° phase switching, and XLR/RCA connections.

1000W RMS for medium to large control rooms

The ADAM Audio Sub15 is designed for monitoring systems in medium to large control rooms, where extension and dynamics must remain controlled even at high levels. The 15.5" aluminum woofer utilizes a 4" voice coil and is powered by a 1000 W RMS / 1200 W Music PWM amplifier.

20 Hz and 120 dB SPL to best extend the low frequencies of your studio

The frequency response extends down to 20 Hz, and the system reaches at least 120 dB SPL at 1 meter according to current ADAM Audio specifications. This headroom allows for the evaluation of transients, energy content, and depth of the program without relying on emphasized or poorly controlled bass.

Aluminum woofer and down-firing bass reflex

The aluminum cone offers high rigidity and is driven by a magnetic system designed to handle large excursions. The generously sized, rounded down-firing bass reflex port reduces ventilation noise and keeps the low-frequency response cleaner.

Crossover and phase for correct acoustics

The subwoofer's low-pass filter is adjustable between 50 and 150 Hz. The 0°/180° phase selector allows for the correction of unfavorable relationships between the sub and monitors in the crossover region, while the -60 to +6 dB level control allows you to balance the Sub15's contribution relative to the system and the room.

Satellite filter and professional connectivity

Main monitors can be left full-range or filtered with an 85 Hz high-pass filter, reducing the excursion of their woofers and potentially increasing clarity and headroom. The unit features balanced XLR and unbalanced RCA stereo inputs and outputs, as well as a balanced Sub Out for daisy-chaining multiple subwoofers.

A low-frequency foundation for stereo and multichannel systems

With 1000W RMS, extension down to 20 Hz, and a mass of 52 kg, the Sub15 is a solution intended for professional installations where the subwoofer must integrate with midfield and main monitors. The level, crossover, phase, and satellite filter controls allow the system to be adapted to various stereo, surround, and post-production configurations.

Who it is for and when to choose it

The Sub15 is intended for medium to large control rooms and systems that require high sound pressure, solid transients, and reliable control of the lowest frequency region. It is a consistent choice for use with midfield and main monitors, as well as multichannel and immersive installations that require an LFE section capable of high levels.
