They're Back

After crafting the highly-touted Sierra Ribbon Tower Floorstanding Loudspeaker, the audio engineers at Ascend Acoustics set off to design a custom bookshelf speaker that offers a similar high quality performance but with a smaller form and price tag. Hand assembled, tested and packaged in the USA, the Sierra-2 is backed by a comprehensive 7-year parts and labor warranty. Because Ascend Acoustics sells directly to the customer, their speakers offer an incredible price to performance ratio, as the money goes towards producing the well-researched, high quality components found in the Sierra-2.

Let's Get RAAL

Thanks to a specially designed RAAL true ribbon tweeter, you get extremely detailed, airy highs with no edginess or fatigue. For the rest of the range, the Norwegian built SEAS 6” Curve woofer can be crossed at higher frequencies without trapping out breakup modes and allows the midrange to deliver a balanced and well-defined sound. With SEAS's exclusive SpiderRing technology to improve suspension alignment for improved power handling, a custom cast magnesium frame, vented pole-piece and open spider for enhanced air-flow and cooling, all combined in Ascend's exclusive layered bamboo cabinet, the Sierra-2 ribbon speakers offer shocking performance and sound.
