Klipsch RP-500M II speakers replace the original RP-500M. Klipsch and their team of master engineers have taken what was already a great bookshelf speaker and made it better with a range of new improvements. New Horns On the RP-500M II, Klipsch had already a winner with the original horn but this time around they have improved it by bringing their 90° by 90° silicon hybrid Tractrix technology into the construction of the horn, which delivers a more efficient and clearer sound than the previous generation without compromising on quality. Linear Travel Suspension The 1” tweeter on the RP-500M II gets the LTS (Linear Travel Suspension) treatment which whilst already a staple of the Klipsch Reference Premier lineup, has been refined and tweaked to give the tweeter the best sound possible whilst removing almost all distortion which makes for a more enjoyable listen. Cerametallic Woofers A new element on the RP-500M II is the use of cerametallic material in the woofer construction, that allows for a 70% increase on the voice coil which in turn improves power handling and consumption that makes these smaller bookshelf speakers powerful without being power hungry. High Grade Finish Klipsch has matched the finishes across the new Reference Premier line up so you can either have a Ebony or Walnut vinyl finish that exudes luxury which means they can be right at home no matter where you place them.
