Rob,
Randy is right. 7XRS MK2 up for sale at $1000 plus $90 for shipping. If the Super Alinco Monitors are a considerable improvement, and I don't doubt they are, then I think I should wait until I can buy those. That's a good point about factoring in the cost of stands. The 24" two post heavy mass loaded stands I have won't work; the top plate is only 9" x 6".
I have no doubt the Vandy subs would work beautifully. I've tried other subs and I'll never part with them. They use three 8" drivers instead of one large driver which makes them very fast, and an internal 300 watt amp Their unique connection method makes them blend seamlessly.
