Montarbo® EARTH PRO 115A is an active subwoofer designed to guarantee extremely high performances in terms of power and quality.

The acoustic design combined with a sophisticated audio signal processing system, defines the new standard of subwoofer, result of a 15” transducer with an high-excursion 4” voice coil and advanced tuning. The cabinet made in birch multiply with a polyurea finish is characterized by a complex internal structure of wood and steel reinforcements, that ensures great sturdiness. The woofer, loaded in a 6th order Band-Pass configuration, guarantees a fast powerful extended response at low frequencies.

The Class-D amplifier features an high-efficiency channel ensuring a 1600 W RMS power that allows the speaker a 135 dB SPL with a frequency response that extends up to 35 Hz. An advanced 24 bit 96kHz DSP ensures consistency, linearity and reliability.

8 presets, 4 of which are user-programmable, make the system suitable for any use, for a versatile and complete plug & play connection. The architecture is based on the o M-Connect proprietary software that, through a simple advanced interface allows the control and the tuning of the installed system.

The EARTH PRO Series subwoofers allow the range of WIND PRO models to be extended up to 28 Hz. A complete range of integrated optional rigging Montarbo® accessories allows the system to be installed in any situation.
