Guess my question is what causes this to happen ?
I am using a pair of Wyred 4 Sound sx-500 mono blocks .
Could it be due to a freq being to high vs the power of the mono blocks ?
While I wont say its ear bleeding loud, its louder than say normal listening levels, but no distortion at all.
Would adding the 1 ohm resistors to the tweeters help at all ?

Is it blowing just on one speaker or both involved? I biamp ST-500's into my IIIa's and don't use fuses. Never have had a problem. Since the amps are rated at 250W into 8 ohms and 550 into 4, I seriously doubt that they are clipping and I never heard anyone complain about too much power with Maggies.
If it's just one speaker, try swapping amps and see if the problem follows the amp and if so, it's probably the amp that has a problem and you should call EJ Sarmento at W4S. If the same speaker fuse blows then try swapping speakers, if the problem follows the speaker then there's your problem. Finally swap the output cables from the pre-amp/source and again if the problem switches then you have a problem with one channel on the pre. You'll need to run out to RS and get some fuses :).

The left speaker blew the fuse a few months ago and guess sometime yesterday the right speaker blew the fuse.
The first time I was playing Bob Segers Live Bullet album and thought it might have been due to the horns and the high frequency and didnt think much about it. Happened to look behind the right speaker today and found that one of the two fuses was blown , but dont really recall turning it up that loud.
On the first incident, it was obvious as there was no top end , but this second time, I didnt notice a change at all in the sound as speaker was playing full range just fine .
Spare fuses are on the way.
When a mid-range fuse blows, it is not as noticeable as the tweeter fuse because you still hear the lower and upper ranges and some of the mid. This is especially true with the 2.7 since the tweeter and mid have identical HP filters so the tweeter "fills in". All you may notice is a drop in volume and perhaps the image moving toward the other speaker.
Hard to say what's going on since you have had a problem in both speakers, and once it was a tweeter and the other time it was a mid-range. The only thing to do is to try and reproduce the problem so you can isolate it.
