Image/soundstage and punch/bass

I have a pair is Magnepan 1.7i and run occasionally an older Paradigm or Snell subwoofer with them. That is about as good as you are going to do for $2200 for the Maggie’s and the rest on a subwoofer. As for the Dynaudio’s: I had been a big Dynaudio fan. That ended when I heard these Magnepans. They replaced my Dynaudio Contour 20s. I’ve heard the Special 40s. But I am sorry. They are not going to cut it against the Maggie’s. I have to say that at $2200 the Maggie’s are the biggest bargain in speakers today. I am waiting for my Mye Stands to come and the Bass should tighten up further. 

You might consider a pair of Magnepan DWM's, about 1700 or so for the pair.  200 to 40 hz to augment the MG12's.  Add 1 sub or two if you can.  I use 2 10s and a 12 to pressurize the room about 65hz.  IMHO opinion this helps the maggies bottom a lot.

Man, I didn’t know ET was still around, let alone making speakers. I have a bunch of Rythmik subs here, but the ones in my main system--- a pair of sealed 15" are crossed over pretty low- and "punch" to me, is more upper bass, not just deep bass. How high do you run these Rythmiks out of curiosity?

Yup @whart, and ET's Bruce Thigpen is still exploring new territory. Check out his TRW-17 Rotary Woofer; output down to 1Hz!

Tekton is getting great reviews in that price range
