IDea BASSO21-A 21 Inch Active Bass Reflex Subwoofer
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, 2 mm steel grille and IDEA Aqua-force 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 structu-res,
allowing for stacked and flown configurations.
