Yes, I heard a pair of them yesterday vs a pair of the HSUs. The 163s have more detail with a richer sound (at least to my ears), but I could live with either of the two speakers. I would not hesitate to buy the 163s at that price point. Yes, near field can go down to 40hz, but be careful which is why the preferable way to go for bass is with a sub or two and not overstress the fronts into a destructive mode. If not overly cranked up, volume-wise, they should be fine.
