I doubt it. If it does go that low, what kind of dbs can it output? Correct me if I am wrong but those highly rated subs like Submersive, JTR Captivator, etc.. are not even rated down that low from their specs. Honestly, it is hard for me to spend that much for a single 13" sub and I love SVS (I have the SB12NSD). I would get the passive Captivator + Behringer EP4000 amp for the price of the 13 Ultra. I see you are in Canada, so SVS might be the cheaper route.
