But using the DSP filters prevents extremely low (and higher) frequencies from reaching the speaker and that's part of good system design- allowing the drivers to work within their capabilities, not trying to make them do what the user/integrator wants. It also compresses and limits the dynamics, which is needed outdoors.

The Sonarray, Niles, Snap, Skywalker and Origin Acoustics "Malibu-style" outdoor speakers are available with this amp- a simple power amp is less able to do what the Crown amp does if there's no way to send to the subwoofer the signal that works best without killing it.
