At Long Last I Have Experienced Phantom!

[superstock]

What I am curious about is if there are folks who play their Phantoms really, really, 'insanely loud' (like >80) during more than like 10 seconds (not to speak of a whole album ).

I went beyond 75 only once, when I listened to Bohemian Rhapsody at 100...

I turned mine up to 85+ today when my Son came home from Uni with some Bass Heavy content that I thought would over drive the speaker. Apart from having to leave the room to view from afar, I think the speakers must have a SAM profile built into prevent the drivers from being overdriven.
I think this is part of the expert range SAM profiling so it's probably the same with the Phantom.
