Hey everyone just signed up just now and hoping to get some answers since I'm a noobie with speaker systems. I recently purchased a Refurbished Klipsch RP-140SA upfiring Atmos speaker pair and as the title of this post states is this echo normal? Bought 5 speakers along with the RP-140SA and only the Atmos speakers have this lingering sound after music/movies are paused. Need to know so I can figure out if I should return these Refurbished speakers. Hopefully the echo comes through and you can hear it. Thanks!
