Thanks for the replies. So although I didn't get a stright yes or no answer, based on some of the responses I would imagine I would have no problem running parrallel out of the left and right speaker level of the tube amp and into both the bookshelfs and the speaker level in of the powered sub. I would imagine this would be my best bet as it would avoid the SW crossover.

If anyone can answer this specific question it would be great. Does hooking it up in the manner above have any effect on the load that the amp is seeing?

There is no appreciable effect. The SW's crossover presents a relatively high impedance to the main amp, below the "corner" frequency. When impedances are connected in parallel, the lowest of the set tends to dominate, according to the Law that follows immediately.

1/Z NET = 1/Z1 + 1/Z2 ... + 1/Zn

If 8 Ohms and 80 Ohms are connected in parallel, the net is approx. 7.3 Ohms.
