Best subwoofer below 40Hz for Magnepan .7?

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. :)

The biggest challenge in adding any subwoofer is room integration.

I know you want to have 20 Hz response, but I wouldn't worry about that as your primary issue. The room response itself can extend or impede the behavior of a sub.

IMHO, your speakers are fine, I would keep them, and get a sub with really great room correction. You'll have a much better result than merely going with larger speakers.

When you audition a sub, you need to audition the sub and the room correction software. See how easy and comprehensive it is to use, and listen for the final results.

Since I build speakers, I do my own room correction with a MiniDSP unit, but that's beyond what most want to do. The solution for you, IMHO is to get a sub that does this for you.

Best,
