POLK RESERVE SERIES

Polk’s new premium Reserve Series speakers use the same custom-made drivers originally developed for its award-winning Legend Series loudspeakers, including the proprietary Pinnacle tweeter and turbine cone midrange, but at a much lower price-point. “This new Reserve Series executes on Polk’s mission to create premium-quality speakers at accessible prices through the application of extensive research and development in advanced materials and acoustics,” said Paul Astbury, of Sound United Australia, which is the new Australian distributor for Polk.

There are nine new models in all, and all are available in matte black, matte brown and matte white finish. There are three floor-standers, two bookshelf/standmount models, three centre-channels and a height model for home theatre applications. “While Reserve does use the same transducers as Legend, it also features multiple new developments of its own, including a new patent-pending X-Port filter and advanced cabinet construction to minimize undesirable resonances” said Polk’s Scott Orth. “In return, you get a classic Polk Audio loudspeaker that is amazingly balanced, offers an expansive sound stage, detailed imaging, smooth midrange and deep effortless bass.”

Polk Audio’s Pinnacle tweeter is a ring radiator design, whose 25mm diaphragm features a waveguide to improve high-frequency dispersion and a critically damped rear-chamber to control unwanted resonances. “This high-res certified driver delivers ultra-clear, crisp highs without unwanted colouration or distortion,” said Astbury, “and the turbine cone driver’s specially moulded cone has a foam core that dramatically increases stiffness and damping which delivers smooth, detailed sound across the driver’s entire bandwidth.”

New in the Reserve Series is Polk Audio’s patent-pending X-Port technology, which uses a set of closed-pipe absorbers precisely tuned to eliminate unwanted cabinet and port resonances which, in the R600 and

R700 is combined with Polk’s Power Port 2.0 design in a manner that Polk says “enables bass frequencies to extend more deeply and at higher output levels than traditional ported speakers.”

The top-line R700 tower combines a Pinnacle ring radiator tweeter with a single 165mm turbine cone midrange driver and two 203mm polypropylene bass drivers to deliver a claimed frequency response of 38Hz to 38kHz –3dB at an efficiency of 88dBSPL. It stands 1144mm high and is 321mm wide and 429mm deep. The dual X/PP2.0 bass reflex port is down-firing. Available now, the Polk Audio R700 sells for $3,299 per pair (RRP).
