Ranked by what users actually praise

Overall Impression

A recurring capacitor failure causes a 'heartbeat' thumping sound in many units. Numerous commenters independently describe the same symptom: a rhythmic heartbeat-like thump coming from the sub, whether idle or in use. The consistent culprit identified across comments is one or two failing capacitors (typically rated 47uf 50v or 63v) on the internal amplifier board, with several owners also finding additional degraded capacitors nearby once they opened the unit up for inspection.

Owners successfully self-repair the fault cheaply, though soldering it is fiddly. Many commenters confirm that replacing the identified capacitors fixed their sub completely, sometimes for just a couple of dollars in parts. However, several note the repair is not trivial: thin circuit board traces, poor visibility, and solder skill requirements made the job painful for some, requiring magnifying tools, solder suckers, or solder paste to complete successfully without damaging the board.

Support and parts are gone, and some units show issues beyond the common fix. Since the model is discontinued, Polk no longer supplies replacement parts, leaving owners to source capacitors themselves or replace the entire amp board with a third-party unit. A few report symptoms the standard cap swap didn't resolve, like persistent buzzing at volume or cabinet-flex noise, suggesting some units have additional or more serious board problems beyond the well-known fix.
