Fulcrum Acoustic, creators of high-performance professional loudspeaker
technologies, has launched its latest innovative, technology-driven product line:
Cardioid Subwoofers. Fulcrum Cardioid Subwoofers are designed with patent-
pending Passive Cardioid Technology™ to overcome the excessive rear low
frequency (LF) radiation that is a major challenge of many loudspeakers.
Fulcrum’s Passive Cardioid Technology, first introduced in their FL283 and FLS115
line array products, is now the basis for a line of Cardioid Subwoofers which
includes CS118 18 inch and CS121 21 inch models.
Fulcrum’s unique Cardioid Subwoofers eliminate excessive rear LF radiation without
the extra cost, space requirements and inconvenience of active cardioid systems,
with a single passive cardioid speaker doing the work of an active cardioid array.
By achieving impressive LF directional control without additional amplifiers, drivers
or signal processors in less than half the space required for active cardioid array
systems, Fulcrum Cardioid Subwoofers allow for cardioid arrays in applications that
might not otherwise have the budget or space to accommodate an active cardioid
solution.
Fulcrum speakers’ subcardioid behaviour is produced by a meticulously conceived
acoustical circuit which balances the position of the low frequency driver, the
enclosure depth and volume, and specially constructed rear-mounted ports which
include a calibrated resistive element. By opting for a subcardioid pattern as
opposed to a pure, hyper or super cardioid pattern, the rear rejection increases
when the modules are deployed in an array.
Fulcrum co-founder and lead product designer David Gunness explains, “Passive
Cardioid Technology evolved from listening to our customers’ needs and directing
our efforts toward satisfying those needs. We see this technology as potentially
game changing for the pro audio industry, and as something we will continue to
develop into new applications going forward.”
