Typical crossover for the bass cabinet would be 120Hz.
If you are lucky you might be able to see some markings on the back of the bass drive units - these markings could indicate the wattage of the bass drivers. In any case, they are undoubtedly requiring the lion's share of the wattage in the system. So, if your speakers are any way close to 1200W in total then I would guess your bass cabinets are a large chunk of 1000W.

Any make/model markings on any of your cabinets?
