RM6005 system problems

Posts: 1
Hi! I have been running this system with an HK AVR 135 for about four years now. The system has been terrific, but in the past few months, the front speakers (esp. l/r) seem to be distorting at high volume (though not just loud passages, also brass and wind solos and high-frequency/high-note passages in choral music). The tolerance/threshold seems to be steadily decreasing, though the system still works beautifully at lower volumes (anything quieter than -10...). So I am at my wits end! Are the speakers getting old? Have they been damaged through (largely high volume) play-back? Or am I overworking the receiver (40 watts per channel fronts and backs)? Thanks in advance!

@nonothing
well first, i would try swapping the front and the back speakers since they are the same in the rm6005 system. if you still hear the distortion, next should try hooking the speakers up to another amp so that you can isolate the problem.
if the avr 135 only has a continuous power output of 40WPC and the speakers claim to be able to handle 100WPC so it doesn't seem like the speakers would be damaged by the amp unless you regularly cranked the amp to distortion levels. the best way to damage a speaker is not to give it too much power, but to try to crank the volume up to a level where you the amplifier clips, even if the wattage of your amp is well below the range of the speaker. this sends all kinds of ugly waveforms to your speakers. so ironically, you could be overworking your receiver, as you suggest, and actually inflicting damage on the speakers (or both). -
call Polk Customer Service
You might have a bad speaker component
You could swap some of the speakers to see if you can isolate the ones that are
distorting.
You might be lucky and the speakers are still under warranty
If you are overdriving the amplifier and it is clipping
then turn the volume down.
Your ears after 4 years would have become use to the sound and
noticing the limitations of your system and
maybe you are now ready for an upgrade to better equipment.

The SPAM before you was reported.CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.
