As an owner of Spica angelus I mostly agree with elevick. My only quibble with his advice is :
1) The highs on the angelus are no so rolled off as some would have you think. I compared the angelus to the spendor s3/5 and they won easily in highs, and destroyed the spendors on imaging and mid-range. They are great speakers for everything except bass.
2) If you're going to add a sub get a powered sub. I use a REL strata and it blends perfectly with the spicas.
I'm not really sure that you'll get the bass you want from the spicas by just changing the wire, since they're a very lean sounding speaker.
