BASSO21
21˝ High Performance Direct Radiation Professional Subwoofer QuickStart Guide
Many key factors are to be considered when conguring the subwoofer section
of a loudspeaker system to perfectly match each application: size/weight,
logistic and operational setups, SPL needs, LF extension, cost limitations, as well
as sound engineer preferences (depending on dierent the type and size of the
event) or audio program characteristics and regional style taste for subwoofer
mixes.
BASSO Series models allow the user to choose the most adequate subwoofer
for any given situation from within a family of products with common nish,
design solutions and performance philosophy as well as shared rigging and
transport accessories.
BASSO21 is a high-density single 18˝ direct radiation subwoofer that delivers
a very natural, linear response in the VLF range from 25 Hz up to 140 Hz.
Built with 18’’ Premium birch plywood and tted with a 2 mm steel grille,
this medium format medium format cabinet is nished with IDEA Aquaforce
weatherized coating to endure life on the road or stylishly integrate in any
installation.
BASSO21 seamlessly matches with 2-way loudspeakers in LUA and EXO Series
maximizing the high-density performance of these systems for a wide range
of portable, mobile and install professional sound reinforcement applications,
from high power club sound systems and medium size live music events to
rental and touring companies.
BASSO21 can be (on demand) served with BASSO rigging structures, allowing
for stacked and own congurations.
