Need opinion of which subs to get

I have been doing a lot of searching, now just looking for input on best sub that would match my speakers. I have it narrowed down to dual SB12-nsd, or dual Rythmik F12SE, or maybe dual Epik Empires. these will be for music only, no HT, I am looking to boost that lower octave if you will, any input appreciated.

Current equipment:
Classe CP-35 preamp
Audio Research D-130 Amp
Tyler Acoustics Linbrook Signatures(1 piece)
