you are most likely turning it up too high so it cuts out to protect the speaker. Get bigger speakers.

As you know that the right is good you can compare that with the left. First look around for burnt resistors or damaged parts.

The next thing to do is with an insulated tool poke the two channels to see what buzz sound each channel makes. You should quickly find the distortion section with this method.

These are relatively simple designed units that produce clear sound. The output transistors are the most likely parts that are defective. Usually when those short, other parts in the driver circuit go as well. While simple for those with experience, it is difficult to state what exact parts will need to be replaced without seeing the actual unit and taking internal measurements. If you have no experience with audio repair, please seek professional assistance. It is easy to cause further damage if improper repairs are attempted.

In this case, the parts cost is likely to be in the $50 range.

It might be easier to "skip" the subwoofer meausrement step in Audessy and tune it by ear instead. Refer to page 52 in the manual, step 6/7.

I use familiar music and test tones when I tune my sub to the mains. Generally, I set the preamp trim to -10db, the crossover as appropriate (80 or below), and then bring up the level knob on the sub to taste. Confirm phase alignment, if possible, by having someone flip the phase (if available) so the response is strongest at the main listening position.

Keep it a little "lean" at first, and over the next several hours or days, bring the preamp level up one db at a time. It takes several days of tweaking to arrive at a level that I find appropriate. Once there, I try to ignore programs with bloated bass - remember, not all recordings are created equal.

Should you fond yourself bringing the preamp level to 0 or above, kick the sub amp level knob up a couple of clicks, and back off the preamp level. It's safer to have the amp do the work, than driving too hot of a signal at the preamp level and clipping it.

Given the relatively small cost of the repair, I'd have the servicer do it. That way if anything happens, he/she is respionsible for it. When I repair this type of speaker, I usually use an old chisel. It is sharp enough to get under the edge and strong enough to pry up the speaker. Just be careful not to nick the cabinet.

First, swap the speakers to see if it stays with the speaker or the amp channel.

Second, disregard the throretical ability of any speaker to handle any amplifier's maximum output. Amp ratings are at a certain power output with a certain amount of distortion. Turn the volume a click higher and power output might rise just a tad but distortion starts to go ballistic. Continue and you get total high current garbage. Clipping (high DC output) will kill any speaker.

Since it seems to go away, I doubt the speaker is damaged, unless torn speaker cone or burnt voice coil can self-repair in a few minutes every time.

Swap the speaker that makes the noise with one of the others. If it acts up on the new channel you know that it's got a fault on it. However if the noise appears on the new speaker the fault is in the amp (perhaps an overheating transitor).
Looking at the picture on fixya of the speakers, it seems unlikely that the speaker units would cause that fault, but the crossover could in it.

the best solution I've found is this:
1. Remove all the tweeter screws.
2. Take a thing metal rod (a coat hanger should work) and lightly tap the tweeter through the top port in the rear until it is loosened and comes out. The tweeter is totally sealed so you probably won't damage it if you need to do this to a working tweeter.

This method also works for the woofer but you need to be very careful to tap the frame or magnet of the woofer and not the cone.

Cinavia is an anti-piracy watermark put onto movies and such. If it pops up on your disc then it's probably a pirate copy.
