I have the Klipsch Epic CF-2 speakers. When a frequency under 40hz is played, I can hear the air being moved very loudly in 1 of 2 of the speakers to the point where it sort of sounds like a diesel engine. The other speaker can play down to 25hz while still being audible and the diesel engine is nonexistent. I think the noise is being made by the bottom 8" woofer from what I can hear, and not from the port on the bottom of the speaker. Also to mention, the speakers are over 25 years old of use. Thoughts and fixes?
