Pyramid Imperial subs vs Audiobahn 1200x sub vs. hyperpro 1200 watt


I have a crunch drive amp that puts out 1200 watts bridged with 800 RMS, i was wandering which sub i should get, the Imperial which has 1200 peak and 600 RMS or the Audiobahn which has 700 RMS, but im not sure how much peak it has.... i assume its 1200 just because of the model #. I think the audiobahn is a better sub, but ive heard that they blow out a lot. Any info about either of these subs would be helpful.
visit either of the subs at:
