3) definitely. There are those who own the speakers and are happy enough with the amount of bass provided, but the clear majority advise to mate this speaker with a good subwoofer as they will really compliment eachother.

Many here and elsewhere (including the Ascend people) really favor the Hsu subs. These subs can be ordered from Ascend too as they have a good relationship with Hsu. Like Ascend, very good quality at a budget price. Hence, the close business relationship.
