I have some mb quart crossovers I can sell you cheap and I think am using the ones in the link if they are the qm200.2's they work real well, also I had the same problem your having if you can play the tweeter until it cuts out then feel the motor to see if it's getting raging hot that's what mine were doing until i switched to a tweeter rated at 70wrms now they don't get warm or fade out ever.
