UM121
Subwoofer speaker
1 x 21" Neodymium
Hybrid bandpass load with profiled vents
The UM121 subwoofer is equipped with a 21-inch speaker mounted in a hybrid enclosure.
The rear section is a bass-reflex configuration with a profiled vent that optimizes warmth in the low frequencies, delivering an impressive physiological effect. The horn flare at the front provides a gain in efficiency at the highest frequencies of the bandwidth, thereby enhancing dynamics and impact.
The use of a 21-inch speaker combined with the substantial output surface of the horn ensures a high and uniform sound level.
The UM121 has been designed for use either on ground-stacked configuration or hanged. Specific accessories allow it to be used above or beside the UM210 speakers. The interactions between UM121 units or with the UM210 have been optimized, resulting in uniform bass and compliance with the latest regulatory requirements for audience hearing protection.
