Only a couple of months late with this info
Okay, here's a bit on the Sapphire XL Center for those of you patiently waiting:
Three-way design with vertical mid-=tweeter array, (as our other centers), 21' wide, 9" tall, 13" deep, approx. 40 llbs It is about 90% magnetically shielded, should be okay in most placements with CRTs. It is the perfect sonic match to the XLs. . . and since I was just asked this, yes, no reason you couldn't use three across the front above or below a screen. More info as it is available!
