that is an old and kinda long story ....iif someone look at the schematic of the 2200 will understand that in the way its made will be easilly unstable at clip levels a serious problem can be that cliping has assymetrical peaks and or behaviour that can be a serious complication combined with fragile tweeters takes you to blown sets ....
A more earthy amplifier could be a solution

Please ignore my last post about about the KEF tweeters it was a moot point. I had a reply from a "dealer" whos knows best (dont they all eh?) as an engineer who actually repairs Hi Fi equipment to component level for a living I can only say my experience of 30 years + is of no consequence to somene who "sells" things,

You have to run your speakers in groups, tweeters in groups of 4, there just not strong enough for this amp, the 2200 voltages are super high and gives lots of current.
single speakers wont cut it with this brute, got to group them.

I used a 2200 to power the main speakers at several raves, after a Carver M1.0t quit on me. I did the amp the kindness of forced-air cooling with a fan and cardboard shroud. The amp is sidelined at the moment, though, due to some problem with the board near the output jacks. This is apparently a common problem.
As for the original problem... time to look at some high-efficiency (semi)pro speakers. Or use light bulbs or other gizmos to protect the tweeters.

The actual relays fail, or is it the solder joints or cracked traces? It's odd that putting tension on the output terminals would fix the problem for a while.
