Can a Pinnacle subwoofer keep up with Spendor S3/5

Can a Pinnacle subwoofer keep up with the Spendor S3/5's? I was thinking of pairing a Pinnacle Subsonic up with them. Is it in the same league? The rest of my equipment is - (Cairn, Primare).
I have a subsonic and it is very fast since it is a sealed design. I think it can keep up with your system. The subsonic will do great in small to medium rooms, after that, it really is too small to have good output. Mine is set to about 25% power and it sound great. Hope this helps.
I dunno, but the Boston PV1000 definitely keeps up with my Spendor front trio. Great $1k powered sub.
Thanks for your input guys.
