INTRODUCTION
The SW215A 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 SW215A 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 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
function to create a transmission path from the back of the transducers to the front.
The SW215A subwoofer system is equipped with two high power 15” (380mm) transducers
capable of long excursion (up to 33mm peak-to-peak), controlled by high stiffness Double Silicon
Spider as centering suspension and by heavy duty surround. The motor structure features high
strength (BL²/Re) with optimized symmetry and excursion controlled by Aluminium Demodulating
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-stiffness
reinforced paper, featuring also invisible water repellent treatment.
The SW215A is processed by 40bit, 96kHz floating point CORE DSP and powered by DA SERIES digital power modules, a new generation of CLASS
D power amplifier with digitally-controlled SMPS. The DA module employed for powering the SW215A delivers in an ultra-compact package a
maximum power of 2000W.
