“New installation after two years of flawless performance is now beeping at different frequencies through the right rear channel only. Re-installed the Rocketfish with a new Harmon Kardon 2600. The right rear speaker intermittantly emits a beep tone at different frequencies. Worked perfectly at my last house. There is a wireless router in the next room. Haven't seen any answers to other issues in the past month on this forum, so I am not hopeful that someone knows how to resolve this.”
