checked overall condition, seemed very good. Cabinets are screwed together and internally braced, wiring there too. All sets of vioice coils read about 5.7ohms, they should be good to go!
Very nice and better made than I would've expected. You're going to love them, though your wife and neighbors may not. But who cares so long as movies and deep music are awesome?
Say, are these the same pair you mentioned a few months back about seeing at the pawn?

If I had to say, I'd think the simplest and least expensive route for you at the moment would be to grab a pair of these from Parts Express (using the AK sponsor link) on your pre-outs or on a splitter attached to your pre-outs if you already have an amp there. 70 Hz is approxiamtely a standard sub crossover frequency, but you can get them in lower Hz values if you prefer to keep most of the bass that from your AR-9s. Then route the interconnects to a spare high-power stereo amp with one sub hooked up per channel or the separate interconnects each to a nearly identical amp (mono or through a splitter to a stereo amp with one channel per voice coil per sub driver).
Of course, if you wanted to get fancy, you could always use an electronic crossover or even a DEQX system. You could also grab a pair of plate amps the next time they go on sale and use the built in crossovers.

I do believe in stereo subs after hearing a pair. I would think an xover point of 45-50 hz would be good for the AR9s, good starting point anyway.
I've eyeballed those filters from partsexpress, if you try them let us know how you like them. I'd try the subs neg/neg & pos/pos, and then switch neg/pos and pos/neg to see if there's phase trouble using the filters.
