Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • No sound from one or more spa speakers
  • Distorted or muffled audio at low or high volume
  • Speaker grille visibly cracked, warped, or corroded
  • Speaker cone damaged from chemical or UV exposure
  • Intermittent audio drop-out during spa operation
  • Buzzing or rattling sound from speaker cavity

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing speaker cutout diameter matches the 2-inch mounting footprint of this unit
  • Verify your spa amplifier or audio control module outputs at 4 ohms — mismatched impedance will damage the speaker or amp
  • Check whether your current speaker uses a push-connector, spade terminal, or direct wire lead before ordering
  • Inspect the speaker cavity for water pooling or mold — address drainage issues before installing a replacement
  • Confirm this is a full-range single speaker and not a tweeter or woofer if your system uses a component setup

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
