Green Mountain Audio Rio Bookshelf Speakers - NICE!

In 2009, this original pair of Rio speakers brought impeccable musicality to small and medium rooms. Advances in casting Q-Stone for our other enclosures had greatly reduced the labor, and when applied to Rio, made it more affordable and kept it very compact. In 2010, one of England's most experienced reviewers gave Rio his Five-Star Editor's Choice Award!

             "This exceptional performer is way ahead of its peers in delivering a vivid and engrossing musical experience, so value for money is, therefore, unquestionably very highly recommended."

- Paul Messenger, HiFi Choice magazine

Features

• High-contrast dynamic range reveals the layers inside the most involving performances, whether played loudly or very softly.
  
  


• Large, front-mounted bass port delivers hard-hitting bass from its Optimal-Point location both on the interior and exterior of the cabinet, meaning it picks up the bass pressures from the woofer inside at the best location, and then pushes that pressure into the room from a location on the front face that creates no interference from the woofer's own front-pressure, or from nearby room surfaces. 
  
  


• Balanced-Phase first-order crossover with new XTC crossover technology brings the clearest, most musically captivating sound possible, with a very easy load for your amp and high efficiency on music.
