Hey! I have been driving a pair of RTi A1's for a little over 2 years with an JVC RX 8010v and have really enjoyed the sound. Today I noticed some crackling from the right speaker and an unhappy smell, and am now noticing rather diminished response in the lower mids and lows, as well as what seems to be a more shrill sound from the tweeter. Any insight and/or suggestions would be greatly appreciated. THX!
