The fast 2500V voltage slope is likely to mess with gate driving scheme by miller effect. In my humble opinion negative turn-off gate drive with low impedance driver is absolutely mandatory here, adding an extra external gate-source capacitance is also an option (to 'clamp' the miller spike into the increased Cgs). +-15V gate driving shouldn't.

The UCC27201 would appear to be ok for a design using a single voltage rail, although it doesn't have the extra functions that are useful for class-D amplifiers, such as an adjustable dead time. You would have to ensure enough dead time to prevent shoot through of your power MOSFET, by adding asymmetrical delays to each of the two inputs.

The A600.1D mono amplifier is designed to drive subwoofers and includes a high pass filter with a frequency range from 5Hz to 40Hz suitable for use as a subsonic filter for vented enclosures or for use with small subwoofers. The low pass filter is adjustable between 50Hz and 500Hz making it appropriate for subwoofers or for midbass drivers.
