Gallo Reference III midrange COOKED

They were purchased new from a dealer in 2007. I'm using an all PS Audio system (except for a Denon multi-player for a transport). I Was using a p300 power plant till about a month ago I purchased a Power Plant Premier here at Audiogon. Two weeks later the midrange drivers in both speakers are gone. They have since been to the factory for repair and returned. Repair wasn't covered by warranty. They said if the speaker was defective it would have already blown during the first three months.

My system:

Trio P200 pre amp

Digital Link III D/A converter (with Cullen Circuits level 3 mod)

GCA 250 Power amp

Power Plant Premier

The speakers are rated a 350 watts; but my PS Audio 250 watt amp cooked the midrange drivers in both speakers. Go figure...

Just wondering if anyone else out there may have had the same or similar problem?

I don't think these speakers are designed to play loud despite their "rating".

The 4 inch mid range is crossed over at 150 Hz to the bass woofer - that is quite low for such a small driver. Also the voice coil is 4 layers - so it certainly isn't designed for good heat dissipation (voice coils get extremely hot when driven hard and can melt or short). It is very likely you simply cooked them.

I suggest to be careful with the volume settings...

I blew three of four mid drivers from using my 3.1s for karaoke.

That would do it - live music (someone singing into a mike) has HUGE dynamic range and clearly this speaker is not designed to handle that. You need either pro studio gear or a heavy duty robust PA type speaker for that.
