FEA-optimised bass port
The front-ported design uses a speckled finish and a port modelled with Finite Element Analysis, so the low end stays clean at high levels.

The Sub 8 PRO combines advanced DSP technology with outstanding acoustic performance, making it an ideal foundation for compact monitoring systems. This networked subwoofer features a high-excursion 8” woofer, FEA-optimized bass port and powerful Class D amplifier.
An onboard Ethernet connection provides access to ADAM Control and its range of management and calibration tools. Users can manually time-align the subwoofer, apply four bands of parametric EQ and upload Sonarworks calibration profiles. Firmware updates can also be managed through the application, allowing future functionality to be added.
Stereo, LFE and Wide modes serve conventional 2.1, immersive and full-range applications. A robust wooden cabinet and protective metal grille ensure durability.

The front-ported design uses a speckled finish and a port modelled with Finite Element Analysis, so the low end stays clean at high levels.

A solid metal grille protects the fibre-reinforced paper woofer without getting in the way of the sound.

Input, mode, level, phase and bass management sit on the backplate beside AES3 digital and balanced analog XLR / TRS connections and a bypass input.

The robust wooden cabinet dampens unwanted resonances, so what you hear is the driver and not the box.

The calibration and management platform for all networked ADAM Audio products: time alignment, four bands of parametric EQ and firmware updates over Ethernet.

Calibrate stereo and multichannel A Series and Sub PRO systems with SoundID Reference and a measurement microphone.

The heart of the Sub PRO line is a high-excursion, low-distortion woofer made from a fibre-reinforced paper material.

AES3 is the professional standard for sending digital audio between interfaces, loudspeakers and subwoofers.

A Class D amplifier drives the woofer efficiently at every listening level, backed by unfaltering DSP.

Finite Element Analysis modelled the airflow over the bass port for more output with less port noise.

Alongside Sonarworks multichannel calibration, two operating modes (LFE and Wide) support immersive audio.
