IDEA BASSO2121 Dual 21 Bass Reflex Subwoofer User Guide

overview

The goal of BASSO 2121 is to bring that world-class touring sub woofer performance in a package equivalent in size, weight and set-up requirements to most standard dual 18” sub woofers available in the market  today, providing tour sound companies with a cost-effective solution for professional touring set-ups and top sub woofer performance for sound productions and installations of any size, complexity and budge

BASSO 2121 mounts IDEA 21” woofers, with 4” dual voice coils, 1600 W power and superlative mechanical and thermal specifications housed in two separated chambers within the enclosure closed by 8 radial large bass-reflex ports. This construction allows a direct radiating bass reflex (with less phase alignment issues when working with line array systems) and the back- pressure inside each woofer chamber to be discharged through the ports symmetrically from the axis of the voice coil and the woofer chassis. This keeps the cone excursion linear, reducing distortion, power compression and improving tone definition at the crossover point and long term reliability. But just as importantly, with this positioning and assembly, the ports become part of the structural reinforcement of the cabinet required to withstand the massive air pressure changes and the mechanical stress while keeping the total size relatively compact.

Like All Idea Loudspeakers BASSO 2121 is built with the necessary structural strength and finish quality required for durable touring use. The high quality 18 mm birch plywood enclosure coated with Idea custom paint solution and a 2 mm steel front grille will keep your equipment safe and brand new after hours of heavy touring.
