Klipsch RP-500SA II atmos speakers are an update to the prior RP-500SA and feature the same updates as with other Reference Premier II models. Silicon Horns As with the rest of the new generation of Reference Premier speakers from Klipsch, they have brought their 90° by 90° Tractrix technology into play, which with their geometric design allows for your audio to find the perfect path without any wastage, which when combined with the silicon composite materials enable for silky smooth sounds that sound completely natural and unforced. New Woofers RP-500SA II comes equipped with an all new 5.25” Cerametallic woofer, which are incredibly rigid and hard wearing without the excess weight for maximum quality and minimal distortion (if any) Add in new voice coils that are 70% larger than the previous generation and you are well on the way to pure audio bliss. Getting Cross On the RP-500SA II, you have the option to switch between Atmos and Surround modes that allow for perfect optimisation with your room. Classy Finish Klipsch has not left these speakers out of the delightful finish stakes, with the options of either Walnut or Ebony vinyl which are perfectly set off with painted baffles that ensure your room looks exquisite with these in them. Excellent Versatility The RP-500SA II is arguably one of the most versatile speakers on the planet, with the ability to be used as an up firing speaker, used at height or even a rear channel by wall mounting.
