Sierra Ribbon Tower Satin Espresso
optional ribbon upgrade

Our goals for this loudspeaker were simple; create a center speaker that perfectly matches the performance of our Sierra Towers but in a compact and placement friendly cabinet. The driver components are identical to those found in the Sierra Towers and the crossover only requires two minor changes to compensate for the larger front baffle width. The dual front slot ports allow for maximum placement versatility and precisely match the low frequency tuning of the Towers.

Featuring our exclusive fully custom neodymium ring magnet tweeter built for us by SEAS, the NrT provides high frequency extension to 28kHz with exceptional transient response.  It provides crisp and airy highs with effortless dynamics and many layers of detail. 

Our midrange driver is housed in its own dedicated critically damped sealed enclosure within the cabinet and is designed to reproduce the critical midrange response.  By isolating the midrange from the rest of the drivers, intermodulation distortion is greatly reduced and detail and separation between individual instruments is greatly improved.

Our dual 5 ¼” long throw woofers handle the low end but don’t let the small size fool you, these woofers provide exceptionally tight and accurate bass reproduction well into the mid 30Hz range.  Bass and mid-bass response are well balanced with surprising punch.  The woofers hit hard and dig deep when required, but due to low stored energy and very low inductance levels, they can also be detailed and subtle when need be, without glossing over the subtle notes that large diameter higher mass woofers can often miss. 

All this combined in our exclusive low resonance layered bamboo cabinet and the results speak for themselves… This is a loudspeaker that simply must be heard to describe. Final results far exceeded our predictions, so much so that that the Horizon is not only one of the world's best center channel speakers, but using these in a left/right/center configuration offers absolutely stunning home theater and music performance.

And for those that seek the ultimate in transparency and detail, we are pleased to offer an optional ribbon tweeter upgrade featuring what is widely considered to be one of the world’s best true ribbon tweeters, our own custom version of the outstanding RAAL 70-20XR with an Amorphous core transformer.

Hand assembled, tested and packaged in the USA, we are so confident of the component and build quality of the Sierra Horizon that we are backing it by a comprehensive 7 year parts & labor warranty.  Pairs will be matched by hand to within ± 1dB and we are including a printout of the actual production line response measurements of each speaker.  We dare say it, but you simply can not find this type of quality control, care and pride from products that are fully assembled and tested in overseas manufacturing facilities.

At Ascend, it is all about performance and we have found a unique way to offer exceptional natural beauty that also offers documented performance improvements.  Now you can have that renowned Ascend performance AND good looks, all in a product that represents the very best of what we have to offer while joining the growing trend towards environmental responsibility.
