#71 Zaph Audio ZA5.2 TM: $383 Madisoundspeakerstore eBay
Pros: CEA2034 spinorama shows a fairly smooth on-axis response. Cumulative spectral decay (waterfall) is clean overall, with only minor lingering energy around 400-700Hz.
Cons: Predicted in-room response is tilted upward toward the treble, which the reviewer flagged as a likely audible brightness. Low sensitivity of about 82dB requires more amplifier gain than typical. Relative harmonic distortion is excessive in the low frequencies, climbing to 6-8% under a 10-volt test signal in the 60-150Hz region - notably worse than typical two-way designs in this price range. Impedance runs close to 7 ohms through much of the audible range, with additional peaks that make it a moderately demanding load for a low-sensitivity design. Vertical directivity narrows unevenly above about 1kHz, typical of this MTM-adjacent tweeter/woofer spacing.
How it compares: Just above it: Role Audio Skiff - $112 more, 6Hz higher bass extension (-3dB). Just below it: Micca RB42 - $223 cheaper, 2Hz lower bass extension (-3dB).
