SW36XFP
passive subwoofer
KEY FEATURES
• Very High Output
• Manifolded Band Pass configuration for very high output in compact size
• High-strength, water repellent, glass fiber reinforced cones • Tetracoil® dual voice coil for extended linear response and increased power handling
INTRODUCTION
The SW36XFP subwoofer is designed to deliver high quality low frequency reproduction
where very high output is a key requirement, together with well defined deep bass response
and fast transient response. Its compact size and light weight make it suitable for several
different uses, ranging from touring applications to fixed installations and high-level dance
clubs.
The SW36XFP is a very high quality powered subwoofer system featuring some of the most
advanced technologies for low frequency reproduction. Its unique and innovative design is
based on a configuration that can be defined as Manifolded Band Pass.
It uses manifolding of the front side of the cones to maximize the mutual coupling between
the two drivers. This innovative configuration does not use any large resonant cavity to load
the speaker, but very compact cavities in order to obtain advantages in terms of definition,
both at the lowest end and the upper bass.
The SW36XFP subwoofer system is equipped with two high power 18” (460mm) transducers
capable of very long excursion (up to 30mm peak-to-peak), and featuring a a large
displacement suspension system. These transducers use Tetracoil technology, where two
different, axially separated magnetic gaps and two inside-outside 100mm (4” ) diameter
voice coils are wound on the same former and suspended evenly in the two magnetic gaps.
This creates an equivalent voice coil diameter greater than 6”, resulting in a larger heat
dissipation area for and increased power handling. Additional key advantages of the Tetracoil
technology are also minimized distortion and a very symmetric and flat inductance curve. Cones are made of very high-stiffness fiberglass reinforced
paper, featuring also invisible water repellent treatment.
