#81 Ascend Sierra Luna: $1,176 discontinued, superseded by Luna V2 eBay
Pros: Ribbon tweeter and a dense, low-resonance bamboo cabinet give it well-controlled horizontal directivity, since the driver sizes blend together effectively. Solid build quality and impressive power handling for such a compact enclosure.
Cons: Dramatic peaks in the bass region around 400Hz, 800Hz, and 1.2kHz - Amir questioned, “A woofer doesn’t dance up and down so sharply by itself in a few hundred hertz?” The port resonates excessively, actually exceeding the woofer’s own output and creating problematic bass “horns.” Measured sensitivity of 80.9dB falls well short of the 83dB spec, requiring about 6dB more amplifier gain than typical speakers. Vertical directivity is poor, making tweeter-height listening position critical. Initial impressions were bright and fatiguing; even after aggressive EQ, Amir called the result “still a bit too bright but much more manageable” and could not recommend the speaker standalone.
How it compares: Just above it: Sehlin Helium - $1036 cheaper, 1.1Hz higher bass extension (-3dB). Just below it: Pioneer Elite SP-EBS73-LR - $427 cheaper, 4.1Hz higher bass extension (-3dB).
