Accurate and revealing subwoofer

Hello, new to home audio, I would need some help to spot an accurate / revealing /  dynamic subwoofer under $1500. It would pair a JL audio Dominion D110.

It has to be less powerfull because the room side to fill with is quite difficult with some bass frequency accumulation at the ceiling level. I am applying some room correction though with Roon's DSP engine.

Here is a short list by now:

• REL HT (1003 ou 1205, yes, I am avoiding passive radiators)
• M&K V10 or V10+
• Dynaudio 9s
• Genelec 7050C

any other sub experimented in this category ? or should I stick to the exact same Dominion?

Context :
- living in Europe
- 30 m2 room (200 inch, L shape)
- Davis Acoustics Courbet 5 speaker (down to 50hz, bright, high and mid ranges detailed)

Thanks.
