QuickStart Guide

---|---
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″ birch plywood, 2 mm steel grille, and IDEA Aquaforce
weather-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 29Hz adding BASSO21 “Infra”
capabilities in large systems and applications those sub-sonic qualities are
required.
DSP AND POWER MODULE
BASSO21-A features an integrated 3.2 kW Class-D power module equipped with PowerCON 32A Mains connectors and XLR balanced audio signal connectors allowing for a simple, straightforward power and audio linking of the array elements.
