Polk MM-6902
Little is documented about the Polk MM-6902 beyond what survives in period advertising and a brief award mention. It was part of Polk’s Mobile Monitor Series, automotive loudspeakers that the company pitched as delivering “home quality” sound in a car. An Audio ad from October 1987 (p.21) listed the MM‑6902 as a $114.90 model, alongside the MM5502 at $99.90 and the MM6502 at $114.90. The following year, Audio (October 1988, p.26) noted that a related design, the MM 6900, had won an Autosound Grand Prix Speaker of the Year award — suggesting the MM‑6902 shared the same engineering philosophy if not the exact configuration.
No specifications (driver sizes, power handling, impedance, frequency response) or production years appear in the surviving records. The MM‑6902 likely used Polk’s trademarked “Mobile Monitor” crossover and driver technology, but that is inferred from the series name rather than confirmed for this specific model. A full technical description, user manual, or service literature has not surfaced.
