Well, that proved to be an interesting experience. They arrived, and for one reason or another, had more dents/nicks than I expected, as well as a dented tweeter. Needless to say, they're now going back, and I'm getting a refund.
I'm poking around on ebay some more, now. I'm finding some other Polk R15 pairs, and considering those. There are some B&W 302s that are still reasonable. I'm also checking out some DefTech ProMonitor 100s. I've listened to bigger DefTechs, and I know that they sound great. I am a bit concerned about how they'll match up with my B&Ws, though. Thoughts/input?
