Thanks for all the suggestions. Toby, I agree with you about the Carvin monitors, you may have skipped over it, but my original post explains that my old blown monitors were Carvins (model 722 - 12 woofer and horn tweeter), so I was looking to upgrade.
Here's an update:
While I had the JBLs, I tried one of the ones that worked side by side with my one Carvin that was still working. The JBL did not seem significantly louder or better. So last night while my wife watched the Grammys (which are getting to be more and more about someone I never heard of presenting an award to someone else I never heard of - also, how many catagories do they have? Including the awards they kept flashing along the bottom of the screen, I believe roughly 30% of the population got a Grammy last night!), I spread my old Carvins out on the living room floor and starting unscrewing like a madman. After swapping speakers and horns back and forth a bunch, and repairing a connector that had come loose, I came up with two working monitors and two with both the woofer and the horn blown. I called Carvin this morning and, to my surprise since I've had these monitors 15 years or so, they had the speakers in stock. $199 including shipping and they'll be here in two days! So I'm going to repair the Carvins and see if they'll cut the mustard in this new situation in which I want to use them. If they aren't enough, I'll think I'll try the Yamahas next. At least I'll be able to get a better price if I sell my Carvins. As an aside, after reading that the JBLs were MDF, I was pleasantly surprised when I cracked open the old Carvins and found they were made of real plywood, just like it grows on the ply tree! Also, the more I think about it, the more I don't want to deal with bringing a power cord to powered monitors.
More wires - aaarrrggghhhh!!!!
Thanks again,
Bill, tgo
