FWIW, the 4594 has a 3" diaphragm and is speced as being good for 1kw peak power above 500hz. The DCX354 does have a higher sensitivity and a more extended MF response than the 4594, indicating a lighter moving mass or a smaller chambre or both, but I'd be surprised if it couldn't handle at least it's program power over 500hz, and more than that above 650hz, excursion wise.
