You'll be glad you did.
Oh, and did anyone mention they rock as well? I have Dire Straits on right now with the sub turned on, just to fill in abit, and one thing that surprises me with the Fostii FE-E drivers, is the amount of impact on drums you can get outta them, once they get going. I don't often listen "loudly," but it is there when I need it. Volume on the ClariT is about 10:00
The F200A, I think are a deal. They are TONS better than the JBL LS-8, that they are cloned from, ever was, and those were pretty pennies in their day. Expensive drivers to me are the Supravox Field Coil 10 inchers, weighing in at something like 45 pounds apiece, $2,500 per pair. And that doesnt include the power supply you must find for the field coil magnet...There are far dearer single drivers out there than those even.
