Introduction and Overview

The subwoofer is the heart of any home theatre system, providing an exhilaration that brings the sound stage physically to life. That is why the same level of attention and care has been taken to develop the Reference Series Model 208 subwoofer as the rest of the Reference Series range.

Key components of any subwoofer are the drive unit, amplifier and enclosure, which in the Model 208 have been perfectly harmonised to deliver gloriously extended, immaculately controlled bass

that floods the listening area.

A 300mm (12in.) drive unit designed with the highest quality components utilises an optimised Strontium Ferrite magnet system that gives 24mm (0.94in.) peak-to-peak of totally linear excursion. Delivering low distortion, accurately controlled bass whether for music or fast action cinema soundtracks.

To get the very best out of the drive unit a 500W Class D amplifier has been custom designed to form a seamless partnership. Utilising a switched mode power supply, top end performance can be delivered

in a highly efficient unit without compromising cabinet design.

The acoustically inert cabinet is beautifully hand finished with a level of craftsmanship and attention to detail that complements the precision of the components it contains. The Bass reflex design incorporates a finely tuned port, delivering both

performance and refinement.

Connectivity and flexibility are paramount which is why the Model 208 has been

comprehensively specified. A range of connection options including phono, balanced XLR and high level speaker inputs ease installation. A cinema and music EQ option enables quick setup and

the subwoofer level, crossover frequency, phase and slope can all be

tuned to meet individual needs.

Overall, every element of the Model 208 has been designed to reproduce low frequency effects with delicacy and precision together with the excitement of sheer power and performance.
