nscanuck,
maybe i wasn't paying attention, but it seems like you are always having trouble with only one speaker correct? If that is the case, have you tried switching the speaker hookups so that each speaker is hooked into the other channel on the amp (it is a 2 channel amp correct?)? That should immediately tell you whether it is the speaker or the amp causing you problems. Of course I may have missed an explanation as to why this won't work, in which case, you may ignore my rambling...


(from what i see so far it seems to point 100% to the amp being the faulty link)

Super hot is not normal. That is what you would get with HF oscillation. As to what causes it, I don't know.

You definitely need to borrow another receiver and see what happens. I'm pretty sure there is something wrong with your receiver.

If you have an ohmmeter you don't need to buy new wire, just disconnect everything, check the ends for loose strands, then measure between the wires and you should see an open circuit (ie the opposite of touching the probes together).

Is your balance control centered or did you have to play with the balance control to get both sides playing at the same level ?

In the short term, don't play so loud

I see your amp has clipping indicators,have you ever seen these light up right before the amp shuts down ?

This has never happened at a lower volume level. Room size is 25x15x8. No clue on db's.

I'm not sure what speaker it was originally. The whole speaker went back so I received a new one but yes the last two times it was the same speaker. I have no balance control on the receiver but I was just switching the jacks around to isolate the two speakers since there is an A/B hookup for two pairs of speakers. To me it sounds like i have damaged the tweeter in that same speaker again.

I haven't noticed a clipping indicator on my receiver. I'll dig out my manual.

I don't see anything on a clipping indicator in the manual. I think I'm going to have to call Rotel and then buy a new tweeter. Crap.

I was talking about the Rotel 1050.It has clipping indicators on the front panel.IMO that's a pretty big room for the 1050 when playing music that high.

You're going to have to explain this to a dummie. How would room size affect the receiver at a loud volume?

I do believe you are just running the amp at to high of a level to acheive the dbs you are looking for.This I think is the source of your troubles.Either do not play your music so loud that you tax the amp or go for a much larger amp.

If you play the same amp and speakers at the same volume control setting in a small or large room it will seem a lot louder in the small room (particularly since you tend to sit close in a small room).

Alternatively, if you move the system from a small room to a large room you will have to crank the volume up to get the same perceived loudness. If your amp isn't powerful enough to play well at the higher volume and the amp starts "clipping" you can end up with a lot more high frequency energy than normal which can blow the tweeter.

Music normally has much more energy in the low frequencies than in the high frequencies, so you can have a dainty light tweeter and still run a lot of power through the speaker as long as the frequency distribution is "music like". If you start clipping, or play pure high frequency tones, you can easily end up putting much more power through the tweeter than it was designed for.

In other words, it's not the big room that affects the receiver it's the fact that you have to crank the volume higher in a big room to get the same volume.

Big rooms need big (more efficient) speakers or big amps or both.
