The best budget sub's for the Maggie 1C's

Considering adding sub’s to help stabilize sound stage to LP12, Ittok/Sumiko Blue Point Special; SLP88 and a pair of CAD 808’s. Any suggestions?
I use to own MGIc long time ago, I believe their frequency range is 45-18000 Hz, If I were you I would only consider a REL subwoofer as REL's are very good match to the maggies. You do not have to spend a lot on REL STrata III if your budget does not allow but you can always try their Q series if you like. These Maggies are very inefficiant ones at 82-83 db SPL so they do not go very loud at all.

Just my 0.02 cents
