I own 2 JL e110’s in my setup and they work wonderfully with my Raidho XT-2’s.
Highly recommend them. Bought them in high gloss for around $1,500 each several years ago, I think the price has gone up to about $2,000 each.
I think you are right not to spend too much, as Class D amps (I think all subs use Class D) can’t be repaired once they fail. I spent about $2,500 on a Paradigm sub for my home theatre setup and it failed after about a decade of use. It’s why I’d never buy active speakers. Who wants to buy a pair of speakers that will only last a decade? JMHO.
