Each woofer in the 12π has been tested to 840 watts continuous RMS power with the heat exchanger inserted. So since the 12π bashorn sub has two woofers, it is safely rated at 1600 watts, continuous. That's also the point where compression sets in and power increases don't result in SPL increases. In testing, I ran at levels above 1600 watts and at frequencies well below horn cutoff specifically to test the mode of failure, to know whether it was mechanical or thermal. The failure mode is thermal, and that's why the heat exchanger is so important to the design.
