The Schiit Loki is an interesting alternative. Unfortunately, having measured a few different subs in a few different rooms, it's going to be a little limited. I mean, it's worth the $150, but often in a sub there are 2-3 narrow bands which need to get cut by a great deal between 20 and 80 Hz.
Add to that I like to use a descending FR, from 20 Hz, loosing 1-2 dB / octave. (JL does the same).
Also, I have never heard a downside in using a miniDSP or similar in a sub only situation.
Still, the Loki may be worth having for other reasons. It is certainly cheaper and more effective than swapping cables to dial in the right sound. :)
