BASSO21-A

21" Direct Radiation Active Subwoofer

Compact 21" active subwoofer, with high output linear response from to 25Hz, for portable professional sound reinforcement systems and very deep LF demanding installations. Designed to operate as an “Infra” VLF extension of the rest of the BASSO Series subwoofers as well as a stand-alone subwoofer, ideal for the reproduction of deep-bass-heavy music styles and for AV and Broadcast applications.

OVERVIEW

BASSO Series models allow the user to choose the most adequate subwoofer for any given situation from within a family of products with common finish, design solutions and performance philosophy as well as shared rigging and transport accessories.
BASSO21-A is a high-density direct radiation subwoofer that brings the genuine 21’’ deep sound out of a very compact rugged cabinet, built with high quality birch 18 mm birch plywood, 2mm steel grille and IDEA Aquaforce wheather-resistant, durable coating.
This powerful, multipurpose subwoofer produces a clean linear audio signal that couples naturally with large two-way loudspeakers like LUA15, EXO15 and EXO18 and flown or stacked with EVO line-arrays in larger systems but BASSO21-A has been carefully tuned to deliver the optimal performance from 21’’ premium quality transducer thanks to the four symmetrical ports that allow for extremely linear excursion of the woofer with minimal distortion and high response in those regions where sound is rather felt than heard.
This extended frequency response reaches 29 Hz adding BASSO21-A “Infra” capabilities in large systems and applications those sub-sonic qualities are required.
BASSO21-A can also be served (on demand) with BASSO rigging structures, allowing for stacked and flown configurations.
