I'm looking for a musical subwoofer to mate to my bx5a deluxe 2.0 speakers, but want to take advantage of the holiday season. 
I'll update this post with links if we find any deals on subs OR DAC's.My preference on subs would be 10" and between 100-250$ on sale, but I'll post anything you guys recommend.
A new DAC this holiday season would be nice as well!  I was eying the udac-2 but if something superior gets discounted, even better! 
Feel free to contribute anything you find in these categories that are on sale.  My wallets ready to go!
 
This is all I've found so far:

So Amazon just posted a supposed 1200 dollar system for 300$. Thing is I haven't heard anything about this subwoofer before, and from the looks of it, I may not be able to hook it up to a udac-2 or my bx5a deluxes if its only designed to be wirelessly interface to a receiver.
