It's interesting how I can vary the effect by changing resistor values. Without the network the bass transient response sounds undercontrolled to my ears. Using an 8 ohm resistor the bass becomes very tight but sounds a bit overcontrolled (the typical Best Buy or Circuit City shopper would complain that the speakers "don't have enough bass"). A 16 ohm resistor provides a nice balance, even on bass transient heavy material like Brian Bromberg's "Wood" acoustic bass disk.I remember Jim Vandersteen was talking about his company's subwoofers, and he said the first model had a Q of 0.7, but some customers were complaining they "couldn't hear the bass". So he modified the subs by incorporating a continuously variable Q control, giving the customer a choice of tight bass, fart box bass, or anything in between.
