Hello everyone, I am totally new to the technical aspect of speakers and other audio equipment so bear with me. I have just recently inherited a pair of Heresy II speakers on risers as well as a Denon PMA-737 receiver. I absolutely love the set up and want to keep it for good. So here's the issue: At first everything worked fine and then in one of the speakers the mids/lows started to crackle even at low volumes. It got bad enough that I just unplugged one and used the remaining good speaker. The same thing started to happen to the second one but didn't get that bad until one day there was a quiet pop and all of a sudden the only signal coming out of the good speaker was extremely faint and heavily distorted/crackly. At first I though maybe there was a problem with the signal coming from the receiver, but I plugged my headphones in directly and there was no problem that I could tell; granted I don't know how to do any tests on a receiver. I would prefer to learn how to do this myself but I am also willing to take it to a pro if necessary. So what are some tests I could perform or potential fixes to this? What tools or other materials would I need? Layman's terms are appreciated! I don't even know how to open them up to have a look inside to take pictures for you all so help there would be appreciated as well. I would greatly appreciate any help. Apologies if I overlooked a thread already answering some of this. If no one has the time to discuss in detail, links to helpful resources are an appreciated substitute. Thank you!
My ProMedia 2.1 system sometimes works fine. Other times when I power it up, it doesn't fully get there. In this case, the power indicator light doesn't come on and there is light crackling/noise that is not affected by the volume knob. Occasionally, the system overcomes its power up problem and finally kicks in, usually with a good low end pop. Again, this is not all the time, just occasionally. When it works, it works great. When it doesn't, it's pretty stubborn and won't power up until its ready. Thoughts?
