Polk MOMO MMC690 — Early Production, Unused, Original Box — Rare Collector Set

For collectors of classic car audio and Polk’s legendary MOMO collaboration, this is a rare opportunity to acquire an unused, early-production pair of Polk Audio MOMO MMC690 3-way 6×9 speakers, complete with their original silver MOMO grilles and original box.

These are not the later revisions — this is the first-run MMC690, identifiable by the black inverted tweeter dome, flush oval midrange, graphite-finish polymer woofer, and the iconic silver six-spoke MOMO grille with the polk (black) / momo (red) motorsport badge. This is the version most sought after by collectors and restorers who value authenticity and early-series tuning.

Collector Highlights Unused condition — cones, surrounds, terminals, and grilles are pristine

Original box included — structurally sound, showing only age-appropriate wear

Early production serial format (AA…)

Complete MOMO motorsport aesthetic — the grille design that defined the series

Discontinued and increasingly scarce, especially in complete form

No current NZ listings — extremely limited availability in this region

Technical Details True 3-way coaxial design

100W RMS / 200W peak

33Hz – 25kHz frequency response

91 dB sensitivity

4 ohm impedance

Mica-reinforced polymer woofer with graphite appearance

Early-run tweeter voicing — smoother, warmer high-end than later silver-dome versions

Condition These speakers appear unused and have been stored carefully. The box shows some cosmetic wear from age but remains intact and presentable — ideal for collectors who value original packaging. Grilles are excellent, with no corrosion or fading.

Why Collectors Value This Set The Polk/MOMO partnership produced some of the most distinctive and well-engineered car audio components of their era. The MMC690 sits at the top of that line, and early-run units with complete MOMO grilles and original packaging are now genuinely hard to find. For restorations, period-correct builds, or curated collections, this pair represents a premium example.
