#84 Jamo C 93 II: $299.00 per pair Discontinued eBay
Pros: Attractive cabinet and finish for the price. The mild midbass rise can add subjectively enjoyable punch at modest playback levels, and the speaker is reasonably compact. Erin measured about 84dB sensitivity through the midrange. Harmonic distortion at moderate output is not the central problem; the much larger limitations are frequency-response accuracy, directivity and compression. Measured bass extension of 68.8Hz (-3dB), with a measured sensitivity of 84dB.
Cons: Extremely non-linear tonal balance: Erin measured treble averaging roughly 5dB above the midrange, with local swings from near the midrange level to +6dB by about 12kHz. The result is hollow midrange, exaggerated apparent detail and a bright, fatiguing balance. Multiple diffraction discontinuities around the crossover and waveguide prevent reliable EQ correction; turning the speakers 30 degrees outward does not fix the irregularity. Midwoofer directivity narrows before the tweeter abruptly widens, indicating poor crossover/directivity matching. Vertical listening position should remain near tweeter axis. Output behavior is exceptionally poor: Erin found compression running off the plotted scale at high level and multitone distortion crossing -20dB (10%) across roughly 200Hz-1.2kHz, which produces audible grain. The grille makes response still less linear. Erin judged the cheaper Emotiva B1+ better in accuracy, soundstage and output. Discontinued.
How it compares: Just above it: Pioneer Elite SP-EBS73-LR - $450 more, 1Hz higher bass extension (-3dB). Just below it: Jamo S 803 - $179 cheaper, 3Hz lower bass extension (-3dB).
