SW218P
passive subwoofer
KEY FEATURES
• Very High Output • Manifolded Transmission Line conguraon for very fast transient response
• Compact size for a very good output-toweight rao
INTRODUCTION
The SW218P subwoofer is designed to deliver high quality low frequency reproducon where very high output is a key requirement, together with
well dened deep bass response and fast transient response. Its compact size and light weight make it suitable for several dierent uses, ranging
from touring applicaons to xed installaons and high-level dance clubs.
The SW218P 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guraon
that can be de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. This innovave
conguraon does not use any large resonant cavity to load the speaker in order to get the lower
octave and this reduces signicantly pressure decay me inside the enclosure, with large advantages
in terms of denion both at the lowest end and the upper bass. At the same me, it doesn’t use very
long transmission line paths as well. Its working principle is an hybrid combinaon between a short
transmission line and an overdamped reex load. Moreover, the maximizaon of the mutual coupling
between the drivers increase the fastness of the transient response while maximizing the overall energy
eciency as well.
The SW218P subwoofer system is equipped with two high power 18” (460mm) transducers capable of long excursion (up to 30mm peak-to-
peak), controlled by high s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 Inner Flux Demodulang Ring. The robust copper 100mm (4”) voice coil is
wounded in two di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ness glass ber reinforced paper, featuring also
invisible water repellent treatment.
