Certainly, it could be used at lower frequencies if diaphragm movement was limited by use of less power. In this de-rated mode of operation, maximum SPL and dynamic range are reduced. Alternatively, you might use a high slope HP filter in the crossover, to help reduce out of band LF energy and thereby reduce excursion.
