TheThomme Posted July 2, 2022 Share Posted July 2, 2022 Woke up this morning to discover my Klipsch SPL-150 sub has a heartbeat. AVR powered off, but the sub going Thump. Thump. Thump. even with the audio input cable disconnected. Anyone have experience with this, or know if it’s a repair vs replace situation?
