Magnepan MG3.6rs and tweeter fuse blowin

Hi, Magnepan's advice sounds correct -- usually this happens when an amp is driven to clipping trying to deliver a sound level in excess of the amp's clipping point. The amps you mentioned would seem powerful enough for most applications. How loud do you listen; how big is your room, and how far away from the speakers do you sit? You might also consider that a component in the chain ahead of the power amps is oscillating in the high frequencies. What preamp and source are you using?? Perhaps you need to look at those components... I have heard that certain cables can make amps oscillate, as well.

You are listening at to high a volume,I am not knocking your taste in music because i also love that cd,However you may have chosen the wrong speakers they are sensitive to loud rock and that could be your reason for blowing fuses.I have owned maggies for sometime and went throug just what you are going through.Turn down the volume and you will see what i mean.Trust me

I agree with the above comments. If your amp is overdriven into "clipping" the fuse on your 3.6's will blow (and some times your tweeter.) I had to learn the hard way with my 3.5's. These maggies are so clean that there is a tendency to crank up the volume control a bit too much. Happy listening.

My guess is that the tweeter's ribbon conductor is so small, that it can't handle the high current. Therefore, it may not just be clipping that's causing the fuses to blow, or the tweeter to burn out, it could be just a very loud signal that could be free from clipping. My MMG's have the "quasi ribbon", and it's likely that its larger/heavier conductor handles more current than the "true ribbon" of the 3.6, since I've driven my KAV 250a to clipping with these smallest of Maggies (that could be close to 600 wpc into 4 ohms), with the fuses removed and bypassed with silver wire, and never had any problems with the tweeters. That said, I am also using only a 15 amp breaker, so my amp isn't able to develop full current. In any case, it's still around 500 to 600 wpc into 4 ohms, before clipping. The ribbon tweeter in your speaker is known to have the smallest moving mass per unit area, of ANY tweeter in the world, and it could be that the small area where the ribbon conductor connects to the lead in wire, just cannot dissipate the heat well enough, when driven at very high power. Turning the volume down some isn't a bad idea at all.
