DECEMBER 2009 SPENDOR CLASSIC R - SPENDOR SP2/3R2 - NEW PRODUCT INFORMATION BACKGROUND For over 30 years the Spendor Classic Series loudspeakers have set a reference standard for discerning audiophiles, musicians and professional sound engineers. While Spendor has created a succession of successful and innovative modern loudspeakers using advanced materials and technology, the Classic series has continued largely unchanged using materials and technology originally developed in the 1970’s. As vital materials and parts used in the Classic series have recently become unavailable, environmentally un-acceptable, or vastly expensive, Spendor decided these were ideal opportunities to introduce some carefully considered refinements. Revision R 2007 Revision R blended some of Spendor’s advanced engineering with original Classic 70’s technology, construction and design to preserve the rich and natural sound character which is the hallmark of every Spendor Classic loudspeaker. Revision R2 2009 The new revision R2 raises the performance substantially with the introduction of a new 22mm wide-surround tweeter, a revised 21cm Spendor bass-mid drive unit, revised crossover and realigned low frequency response. These improvements take advantage of many engineering and sound quality improvements which Spendor has recently developed for new models like the Spendor SA1, A5 and A6. Despite the clearly audible improvements Spendor has not lost sight of the challenge – to improve this Classic design without losing the warmth and charm of the original. The 21cm Spendor UK designed and manufactured bass-mid drive unit now incorporates phase correction technology in the form of a focusing magnet motor pole extension, to controls spurious phase and frequency response variations in the crossover region. Frequency transition between drive units is more coherent due to improved phase matching. The result is a more even and natural sound and a more holographic sound-stage. Sound remains open and relaxed at higher listening levels due to the improved thermal dissipation of the new drive unit. An all-new 22mm wide-surround tweeter combines the extended frequency response of a small diaphragm with the low frequency characteristics of a larger diaphragm to give stable low distortion response over a very wide frequency range. The crossover network has been re-engineered to improve conductivity and signal routing and to eliminate magnetic interaction between inductors. Revised filter alignment integrates the drivers seamlessly. Specific geometry of the grille aperture dramatically reduces acoustic interaction. The new grille substantially improves sound stage and off-axis response. All internal cables have been up-rated. Heavy gauge, high purity multi strand copper conductors, individually silver-plated, with halogen free dielectrics, give wide-bandwidth and clean signal transmission. The SP2/3R2 presents a very easy-to-drive 8ohm load and it is compatible with all types of amplifiers, from powerful solid state to the most esoteric tube designs. The traditional Spendor ‘Classic’ cabinet engineering, thin walls with heavy damping, has been enhanced by the use of modern rubberised damping panels. The damping interface between the cabinet wall and the damping material is significantly improved due to more consistent temperature stability, spurious energy is dissipated more efficiently, the result is improved sound.

While the technical performance is subtly improved there is no significant change to the overall technical specification and each pair of Spendor Classic Series loudspeakers is still calibrated and matched to stringent broadcast reference standards. All Spendor drive units and crossovers are individually calibrated and pair matched during manufacture. The new Spendor Classic SP2/3R2 delivers clearly audible improvements in resolution, stereo imaging, low frequency extension and articulation whilst carefully preserving the natural charm of the 70’s original.
