I've been dealing with my left front channel bass cutting in and out for some time, and finally it just stopped altogether. Also, my right channel sounds pretty distorted as well; both of the right channel drivers seem to be making sound, but there is definitely a buzz/crackle apparent on the lower frequencies. These speakers are fairly new (1998) RT7, so I don't think they are just worn out. However, I do have a teenage son that is very keen on the BIG BASS in his hip-hop tunes. My guess is that perhaps they may have been driven pretty hard while mom and dad were out of the house.
I took both speakers apart. The left speaker (the one that was not producing any bass) does not seem to exhibit any visible damage. Perhaps there is an issue with the crossover on that one. ??? The right speaker (the one that made the electric grinding noises in the bass) definitely was not in such good shape. The cone is split at the bass near the driver area. Ouch!
I think I would like to replace the woofers, assuming replacement parts are available and not cost prohibitive. If so, that would seem to solve part of the problem. Then there still may be an issue with the crossover(s). How can one tell if crossovers circuits are working properly? If not, are they replaceable components as well?
Any other ideas or suggestions or something that I should consider or look into?
Thanks for any advice or assistance in helping me to resurrect these speakers.
