Hi Craig;

1. The 'my room' feature is a work in process. We're trying to find a programmer who can make it work the way we picture it. Stay tuned!

2. In deciding what features to include in our subs, the high cost and limited usefulness of variable phase settings eliminated it as an option.

3. Yes, it does make sense to adjust down the crossover frequency control , especially if the sub is not on the same plane as the front channels.
