B120
Subwoofer Specifications
Transducer
The B120’s proprietary woofer diaphragm is constructed
of micro ceramic composite (MCC), a new material
created by adonizing both sides of an aluminum
core. Anodizing both sides of an aluminum core adds
strength and stiffness – but very little weight – to a material
already well suited for use in transducer diaphragms.

Fully Parametric Room EQ
Any subwoofer’s performance will be, to at least some
degree, affected by the acoustics of the room in which
the subwoofer is used, and where in the room the
sub is situated. Certain low-bass frequencies may be
adversely affected by standing waves (also known as
room modes), where some frequencies are exaggerated
(peaks), while others might be diminished (dips). To
tame the subwoofer’s response in the listening room,
the B120 features a parametric room EQ function, with
controls for frequency, level and bandwidth to tune out
room-induced response anomalies.

Cabinet/Port
The B120 cabinet is constructed of rigid MDF with
extensive internal bracing to reduce cabinet-induced
colorations. A downward-firing port allows for placement
against a wall or in a cabinet. Rubber-padded feet ensure
optimal stability on any floor surface.
