There is no single processor like the SP-24 or its successor product. (As of October 16, 2020)
As an alternative, for example, you can use a power amplifier with a built-in processor as shown below.
BOSE / PowerShare PS602P
PowerShare Editor
-Excerpt from the manufacturer's site-
Integrated Loudspeaker Processing with Optional PowerShare Editor Configuration. For applications requiring additional signal processing the PowerShare Editor Software offers real-time selection and control of Bose loudspeaker EQs, 9-band PEQs, mixing, crossover, limiters, delay, and mute/output polarity through a USB connection. For basic setups without a PC, rear-panel settings allow installers to recall Bose loudspeaker equalization and protection per output channel. These features eliminate the need for an external signal processor in many applications.
