#99 Yamaha NS-10: $499 Discontinued eBay
Pros: Legendary studio reference monitor with a well-documented history; Yamaha’s original spec sheet included genuine measured data (frequency response, distortion, impedance, polar response) rather than just marketing numbers, unusually transparent for the era. Distortion, compression, and multitone performance all measured better than the reviewer expected for a decades-old design - in some respects competitive with newer speakers he’s tested. Vertical dispersion holds up reasonably well for a speaker of this vintage. The redesigned “Studio” cabinet is more robust than the original, with crossover tweaks and nicer binding-post terminals. Sealed cabinet design allows placement close to a wall without added boominess, though at the cost of overall bass extension.
Cons: A pronounced peak of about 7dB above the midrange average around 1.7kHz gives the sound a forward, bright, or “tinny” character - this is the real underlying issue, and it wasn’t actually fixed by the “Studio” revision. Comparing the Studio version’s measured response to the original NS-10M’s published data, the original arguably measures more linear - Yamaha’s fix (lowering tweeter level by 2-3dB) left the core midrange peak largely untouched, addressing the wrong problem. The famous “tissue paper over the tweeter” mixing-engineer trick doesn’t actually help - testing it directly showed it adds diffraction and comb filtering rather than correcting the real midrange peak. Poor horizontal directivity, especially in its designed on-console orientation - usable window is only about ±20° off the tweeter axis before tonal character shifts noticeably. Directivity mismatches between direct and reflected sound make this difficult to properly correct with EQ in a typical farfield listening setup with nearby wall reflections. Bass is quite limited (F3 around 100Hz in most rooms once corrected for the inflated on-axis sensitivity reading), typical of a small sealed monitor design. Correcting the main midrange peak with EQ likely requires two bands rather than a single simple filter, since the peak isn’t perfectly symmetrical. Possible age-related tweeter compression at very high output, potentially from degraded ferrofluid affecting heat dissipation in these decades-old drivers. Discontinued.
How it compares: Just above it: JBL 4319 - $3501 more, 0.7Hz lower bass extension (-3dB). Just below it: Dayton Audio MK602X - $350 cheaper, 5.2Hz lower bass extension (-3dB).
