The open question is how much will they cost?
The 30.7 sounded poor in 3/4ths of the road trip demos, and 2 years later how many dealers have sold even one pair?
The top Magnepans (30.7 and 20.7) are not even on demo at most all the dealers.
If Magnepan is to compete with Magico and Wilson, the dealers need demos in the stores!
Also the new swarm milti-subwoofer type of arrangement with a 3.7i or 20,7 may be as good, and much cheaper.

More appealing to frugal Magnepan buyers.
