The sub's crossover should be either disabled or (if it can't be disabled) set to the highest possible setting.

The InRoom Silver LCR is rated down to 70Hz (-3dB), so I'd probably start with 100Hz crossover point for those, although 80Hz might also work out. I didn't see an OnWall Bronze, but the InWall Bronze is rated to 95Hz, so I'd definitely look at 100Hz for those and could probably stand to go higher. The Bravo II is also rated to 80Hz, so you could probably just set it to 100Hz and forget about it.
