SW215P
passive subwoofer
KEY FEATURES
• Very High Output • Manifolded Transmission Line configuraon for very fast transient response
• Compact size for a very good output-to-weight rao
INTRODUCTION
The SW215P subwoofer is designed to deliver high quality low frequency reproducon 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 applicaons to fixed installaons and high-level dance clubs.
The SW215P is a very high quality powered subwoofer system featuring some of the most
advanced technologies for low frequency reproducon. Its unique and innovave design is based
on a configuraon that can be defined as Manifolded Transmission Line.
It uses manifolding of the front side of the cones to maximize the mutual coupling between the
two drivers, while loading the back of the cone with a large-size transmission line that has the
funcon to create a transmission path from the back of the transducers to the front.
The SW215P subwoofer system is equipped with two high power 15” (380mm) transducers
capable of long excursion (up to 33mm peak-to-peak), controlled by high sffness Double Silicon
Spider as centering suspension and by heavy duty surround. The motor structure features high
strength (BL²/Re) with opmized symmetry and excursion controlled by Aluminium Demodulang
Ring. The robust copper 75mm (3”) voice coil is wounded in two different layers both outside and
inside the coil support, then doubling the coil surface exposed to air cooling and consequently
improving the long term thermal capacity of the loudspeaker. Cones are made of very high-sffness
reinforced paper, featuring also invisible water repellent treatment.
