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.
