I know Chris (Audyssey) many times on the AVSforum has stated you should set your speakers to small, and start with an 80hz crossover to follow Tom's (THX founder at Audyssey) recommendations. He has mentioned that many speakers are capable of a lower rolloff, but you should still use small and let the sub do the work it was intended to do. Sounds like something Alan has been preaching for years. \:\)
