Re: Bummed - friggin' speakers busted.
Follow-up, I got the new speakers in today, they're in the rear in the theater for surround sound. I'm not sure how they're going to sound, but I suspect that they will completely kick ass. I've been increasingly annoyed at the localization of the direct radiators in the back, and have been curious about bipolar and dipolar designs.
In other news - I replaced the Modus 1.6 towers in the office with my previous surround speakers, a pair of old Mirage 290iS bookshelves.
Oh. My. Goodness.
These speakers sound absolutely LOVELY. My office is SO much more
musical now than it was before. I have to get used to not having the (overemphasized IMO) big powerful bass of the towers.
I'm listening to the DVD-A of Donald Fagan "The Nightfly" right now on the Technics DVD-A10 that I use for a CD player in the office. The stereo receiver is an early 90s Philips FR-930, a nice old analog prologic receiver run in stereo mode.

Also - a replacement tweeter can be had from Wharfedale for $50 or so. I'm handy with a soldiering iron - I'll probably fix the busted Modus tower and sell it. The Modus speakers are fine, they really kicked ass in my theater before I had my subwoofer built. Not my style though.
My goodness these Mirage speakers sound sooooo good. I had forgotten.
Thanks everyone, I'm happier than I could have imagined that this speaker broke!
