I have a pair of Totem Arro's in a small living room set-up, paired with a little El-34 Jolida integrated and a Rotel CD player. While they work perfect for the intended purpose, deep bass is obviously not a strength. But then I'm sure they would perform admirably as surrounds. They are nominal 4 ohm speaker.
FWIW, the bottom end does improve with the addition of 20-30 lbs of sand/lead shot added to the enclosure.
