Subwoofer

Subwoofer, equipped with a 15-inch loudspeaker, powered by Class D amplification of 1000 watts RMS, the whole unit develops a maximum SPL of 130 dB! The functions of the integrated DSP can be controlled remotely or simply selected via presets including cardioid configurations, giving a very wide range of options for system configuration.

ARTICLE N° 88415
Uncontrolled bass dispersion, on and behind the stage, is a high risk of feedback in the low frequency range.
Professional sound engineers meet this stringent requirement for acoustic isolation with cardioid technology for subwoofers.
This technical trick can now be easily performed on Sub LINEAR 5 MK II, without the need for measurement technology: simply select a preset and off you go!

The cardioid configuration attenuates the bass sound pressure of spherically radiating subwoofers by up to 34dB. There is a slight increase in sound pressure of around 2dB in the front sound dispersion.
The result is a directional cardioid radiation pattern.

Cardioid sound reinforcement technology can be used with vertically stacked subwoofers and also with horizontal configurations.
The new 1:1 vertical and 1:1 horizontal cardioid presets are unique features of the Sub LINEAR 5 MK II.
