guys, thanks for the good advise. i've toyed with placement/height per your suggestions and found the following:
1. raising 'em off the gorund does indeed tighten the bass--i've got 'em on 18" stands and will try raising 'em further;
2. they really don't work well in the middle of the room (too diffuse)--curiously, they do sound better and more focused near the corners;
3. the grills are least acoustically transparent i've encountered--removing them makes the highs and mids much airier, but also causes the woofers to lose some grip.
I'll experiment further--please keep the suggestions coming.
