New Klippel NFS optimized version!
With the continuing success of our remarkable Sierra-2/2EX speakers, it was our goal to take that level of performance and offer it in a stunningly beautiful yet surprisingly tiny cabinet.
Featuring a custom RAAL true ribbon tweeter and our exclusive 4.5" SEAS Curv™ woofer all combined in our remarkable low resonance layered bamboo cabinet.
Follow the development of the Luna from beginning to end:
Our new V2 version has been fully optimized using advanced 360-degree Klippel NFS measurements. These optimizations provide significant overall performance improvements, specifically in the area of reducing/eliminating port resonance, enhancing and improving overall directivity, and providing more accurate tonality.
With the major success and continual overwhelmingly positive customer feedback for our Sierra-2 speakers, we began heavy research into seeing what we could achieve in trying to offer that level of performance in a much smaller and more placement-versatile speaker.
It was an easy decision to use the same custom RAAL ribbon tweeter used in our Sierra-2, but we needed a woofer that would provide similar dynamics and performance to the exceptional woofer we use in our Sierra-2, only it needed to be quite a bit smaller. Our requirements were simple, but yet nothing existed, at least not just yet.
Much like with the development of the Sierra-2 woofer, and taking full advantage of our relationship with SEAS of Norway, the process began. We quickly learned that woofer design becomes exponentially more difficult as size decreases. We went through more prototypes for this woofer than we have for any other transducer we have ever had made for us. After slightly over a year, and just when we thought we were going to have to take a different approach – SEAS nailed it.
Combined with an advanced crossover and all housed into a stunningly beautiful FEA and advanced 3d CAD designed Made-In-The-USA layered bamboo cabinet, these speakers beg to be both heard and seen!
The Luna has exceptionally wide and linear horizontal dispersion thus it presents a shockingly large and enveloping soundstage, even in large rooms. Its performance belies its small size in such a way that in our many public auditions of the Luna’s, listeners continually throw out comments stating “these speakers sound so much bigger than they are”.
Hand assembled, tested and packaged in the USA, we are so confident of the component and build quality of the Luna that we are backing it by a comprehensive 7 year parts & labor warranty. Left / right pairs are 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.
We must warn you though, once you have heard what these RAAL true ribbon tweeters are capable of, there simply is no turning back...
We thank you for your interest!

* The below anechoic measurements are high-resolution full-range 360-degree scans taken with our Klippel Near Field Scanner. A minimum of 800 individual measurements are taken to generate these advanced measurements, typically requiring a minimum of 6 hours. These are unsmoothed and fully conform to CEA/CTA-2034 standards.
These measurements are as accurate as is currently technically possible.
Due to the costs, space requirements and complexity, very few manufacturers own or have access to a Klippel NFS, nor would they ever publish such detailed data on their products. Ascend Acoustics is and always has dared to be different.

*Note: Our exclusive Off-Axis Estimated In-Room Response measurement is a critical performance metric. It is an accurate comparison of the differences a listener should expect to hear sitting at different off-axis angles from the speaker; on-axis, +/- 10 degrees horizontally, +/- 20 degrees horizontally and +/- 30 degrees horizontally.
This is a modern and more accurate prediction of in-room speaker performance at different listening angles compared to a simple off-axis measurement graph. This measurement graph accounts for both direct sound and indirect sound and requires thousands of individual off-axis measurements that are then processed through complex algorithms to derive the results. In comparison, an off-axis measurement is just a single response measurement that does not account for the actual directivity of the speaker and is not representative of what we actually hear.
This measurement clearly shows the remarkable off-axis response of the Luna. There is less than 1/4dB of deviation between the different off-axis positions and this is based on accepted science determining what the listener will hear from this speaker in a typical listening environment.
The Luna’s versatility is unmatched, crossed at 80Hz and used with a sub, they make terrific mains sounding nearly identical to our Sierra-2/2EX. The Luna’s are the perfect surround speaker with any of our ribbon speakers as fronts, or for someone seeking the ultimate desktop monitor. Using the integrated mounting hardware, the Luna’s become the perfect on-wall speaker.
The Luna combines extraordinary dynamics, realism, spaciousness, transparency and detail while doing so with such finesse and refinement that there is never a hint of harshness. Although bass is limited, it is impressive for a speaker this size and there are no issues running them full range. Music and home theater simply sound more realistic, providing a more satisfying emotional connection. We must warn you though, once you have heard what these true ribbon tweeters are capable of, there simply is no turning back...
