BASSO21t
21˝ High Performance Band-Pass Touring 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.
BASSO21t is a 21˝ subwoofer that has been designed to deliver high SPL levels
and eciency out of a medium format enclosure delivering serious power
density.
The 5th Order Band-Pass design together with the premium-quality European
21˝ woofer deliver serious SPL with maximum impact in the 50 to 100 Hz octave
and the extended sub range of 30 Hz allows for Infra extension application into
any system.
BASSO21t features four integrated handles and two 35 mm pole mount sockets
for vertical and horizontal set-ups. BASSO21t is compatible with optional BASSO
rigging frames for ground-stacked congurations. Optional wheels kit is also
available.
