Crossover points

I have two 8" Diamond Audio subs in a sealed enclosure and one RE SX12 ported tuned at 36hz.

I'd like the 8" subs to play the higher bass frequencies perhaps as a mid-bass setup. The 12" sub will then be used for the lower frequencies.

Problem is, I don't know what crossover points would be good for a setup like this. Should the sub play from 36 - 80hz, and then the 8" subs be crossed over at 80 (hpf) to 120 (lpf)?

Please throw some numbers out there so I have something to start with. Thanks.

Thanks a million for the responses. Finally got the HU in, setting crossovers now.

Because the 12" enclosure is tuned at 36hz, shouldn't there be a HPF at 36hz to prevent over-excursion, or is this a non-issue? I have about 800w RMS going to it.
