Klipsch R 80SWi wireless subwoofer troubleshooting

Typical problems with the Klipsch R-80SWi wireless subwoofer and their fixes include:

  • Receiver setup: Verify that the receiver’s settings are set to “Small” for the front speakers or the entire system. The front speakers will receive all low-frequency information instead of the subwoofer if the speakers are set to “Large” or “Full Range.” Additionally, check that the receiver’s receiver settings have the subwoofer or “sub out” channel enabled or active.
  • Connection issues: Look to see where the subwoofer is connected to the receiver’s back. It must be connected to a channel marked “sub out” or for a dedicated subwoofer. It’s possible that it’s connected to an RCA port that isn’t transmitting any audio or low-frequency data. Verify the type of cable being used to connect the receiver and subwoofer. RCA cables or “shielded” subwoofer cables should be used for this.
  • Crossover settings: The crossover is probably set too low if there is an audible space with no bass between the beginning of the subwoofer and where the low end of the front speakers ends. For their complete system, we normally advise consumers to begin with a crossover point of 80Hz. THX recommends using this typical crossover point because it should close any “bass gap” difficulties.


Unquestionably a top-tier subwoofer, the Klipsch R-80SWi fills your living space with powerful, immersive sound. It is a standout option for audiophiles due to its wireless connectivity, modern style, and wide range of uses. Although it can cost more, the performance and quality make the investment worthwhile.
