The Reference 1 is a completely new model for 2011 incorporating all our technological expertise in speaker design.With the Reference Series we've sought to improve upon every aspect of current speaker design to create a true, balanced, dynamic, wide-bandwidth and minimal colouration loudspeaker. Cabinet: Constrained laminate layer construction for maximum resonance damping. A specially designed 7mm MDF/3mm high density rubber/5mm MDF sandwich material is used throughout the cabinet enclosure to minimise resonance and external cabinet noise. Bass Driver: Huge underhung motor assembly for maximum linear accuracy and control. The motor system comprising twin-wound aluminium voice-coils is thermally bonded to the aluminium cone for absolute minimum distortion and long-throw pistonic accuracy. Tweeter: The now well-established Vifa Ring-radiator tweeter is used here in our own custom, upgraded specification. Coupled to our DXT? Lens assembly for improved in-room response and dispersion matching to the bass driver, this is one of the finest tweeters in use today. These features wrapped into a compact, elegant design and luxuriously finished with real piano ebony lacquer mark the new Reference Series as the pinnacle of current small loudspeaker design.
