I drank the kool-aid and tried to integrate a number of subs into LaScalas, and I can only describe the effect as smearing the bottom end. In the end I prefer them without any subs. The woofers are Crites which might buy a a few db on the bottom, but I can't say anyone had ever listened to them asked where the bass was. Back to the OP! I can't say that I think you need to do anything but connect them to the 8 ohm taps!
