Subwoofer suggestions for budget system?


My current setup is a pair of Magnepan 1.6 speakers, a pair of Schiit Vidars, Schiit Sol turntable w/Goldring E3 cartridge (I have a VAS-rebuilt Denon DL-103 with Ebony shell and microridge stylus when I can get someone to come set it up for me), Mani 2 phono stage, Asgard 3 headphone amp acting as preamp, Schiit SYS as source selector, Modi 3+ connected to Volumio for streaming digital and an Orchard Audio RCA-to-XLR converter to drive the Vidars in monoblock mode.

I'd like to add a subwoofer to the mix that can keep bass out of the Maggies.  I'd, of course, prefer a dipole sub to go with the dipole speakers, but not terribly picky ATM.  My budget is around $200 to $300 for now.  I have been very tempted to build a pair of my own subs, but that's not in my budget right now.

Suggestions?

$200-300 is pretty low. Subs are heavy to ship. If this was me, I'd search US AudioMart using my zip code and a 100 mile radius to see who nearby wanted to sell a subwoofer; then, assuming it looked ok as a deal, I'd arrange a local pickup. This strategy avoids the costs and risks of shipping and maximizes the value. 

what type of music do you listen to that you are missing the low frequencies for?

I am in the same boat - low budget, considering a sub - but I am not sure it would make a significant difference for me

@hilde45 shipping for a 12" sub with UPS ground anywhere in the lower 48 < $40. Not worth driving around for hours

@grislybutter -- thanks for the correction. Makes me feel better about my own ability to sell a sub, someday, if I downsize.
