They xover at 250hz, so just a Class-D for the bass will be fine that’s what their good at fast dry bass should match up to the speed of the esl's better.
Also get one with input level controls and that has higher gain than your esl amp, as you’ll have to match up the gains.
And it’s also good to have level controls on the bass amp because on hot humid days the esl panel looses a couple of db efficiency, and the sound "can" get a touch bass heavy, but with the level controls you just back off the bass a touch on those days
