USER MANUAL
SW215P
passive subwoofer
KEY FEATURES
• Very High Output
• Manifolded Transmission Line con
fi
gura on for very fast transient response
• Compact size for a very good output-to-weight ra o
INTRODUCTION
The SW215P subwoofer is designed to deliver high quality low frequency reproduc on where very
high output is a key requirement, together with well de
fi
ned deep bass response and fast transient
response. Its compact size and light weight make it suitable for several di
ff
erent uses, ranging from
touring applica ons to
fi
xed installa ons 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 reproduc on. Its unique and innova ve design is based
on a con
fi
gura on that can be de
fi
ned 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
func on 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 s
ff
ness Double Silicon
Spider as centering suspension and by heavy duty surround. The motor structure features high
strength (BL²/Re) with op mized symmetry and excursion controlled by Aluminium Demodula ng
Ring. The robust copper 75mm (3”) voice coil is wounded in two di
ff
erent 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-s
ff
ness
reinforced paper, featuring also invisible water repellent treatment.
