Wow, she's a tough one. Laugh  Have you thought about accidentally over-driving them and blowing out the tweeters?  Then they'd be broken.  Wink  

Otherwise, regarding the domestic politics involved, it's a process.  You could start with something like "Honey, does this recording of Artur Rubenstein actually sound like a piano?". (Be sure to turn the bass and treble all the way down.  No, wait, she'll know.  Forget that.)  Although she may have a more or less immediate response, the question will stick in her head.  If you don't own a piano for her to compare it to, casually take her to a place that does, like a local jazz club or a music store.  A week or two later, you might try this:  "Wow, Scheherazade is so romantic.  I bet the violin solo would sound awesome on some really nice speakers."  Don't even ask for a reply, just let it simmer.  Get the plan?  I guarantee that within six months, she'll think that buying new speakers was her idea.  Wink

Well, she just picked out this car, and we pick it up on either Nov. 19 or 20:  http://herbchambers.com/V...che_911/vehicleID/238864

No speakers for quite some time!  Wink
