Mating sub(s) with Maggie 1.7i

Have pretty much talked myself into trying these, should be fantastic for maybe 70% of my listening. Think I will miss the next octave for the other 30%, sooo …

Everyone talks about adding subs, but also the challenge of integrating coherently, and May toss out a few favorite models (Rel, JL, etc).

Easiest May be adding 2 DWM panels, but they really don’t go much lower, and almost as expensive as the speakers themselves.

I have the ingredients for a (Acoustic Elegance AE15) 4-driver 15” infinite baffle sub (Or 2x2) … I am thinking an IB would be a great match, generally very tuneful and fast, sometimes cannot tell there is a sub there, just extended FR.

I also have the ingredients for a single 12” sub of whatever design. Its a well-regarded Adire Shiva, and I used to use in a sealed 88 liter configuration … very tuneful and fast, integrated pretty well.

And of course, there are any number of manufactured subs out there.

Your thoughts on which path to trod?
