I just got this HTiB, which has five small satellites and an active subwoofer. It doesn't have a crossover setting on the sub itself but in the A/V Receiver menu there is a crossover setting with the following choices: 40, 60, 80, 100, 110, 120, 160, 200Hz. (80Hz is default). Is there a particular setting to target or should I simply turn it up to 200Hz, since the other speakers are small (including the fronts)? If it matters, the auto-cal sets it to 120Hz in 8 ohms mode and 80Hz in 6 ohms mode.
