you can run both of them in parallel and run the amp at 1.5 ohms, if you really want to try that woofer.
there's a review floating around somewhere, they said it wasn't that great.
mind if i ask what kind of a deal you can get these for?
if they're cheap, it may be worth a shot, but i wouldn't expect anything w7, d9, or type-x'esque from it
i got a pair of the xxv-04s kenwood 25th anniversary component speakers, which had an msrp of $999, and were supposedly kenwood's flagship speaker, and they were airy and clean, but didn't have much output. they're not my 1st choice for drivers.
