Even if we assume the Crown amp has infinite power capabilities, I still look back to the TC2k tested outdoors at 2m with 2000 watts on a 115db sweep down to 10hz with no highpass and no bottoming or other mechanical driver issues. I'd hope an 18" with higher rated excursion capabilities from the same company could at least do that at 6db louder at all frequencies.
