I have my 1.7 set up in a room by 14 by 20 and it works very well.. Had MG11b's and SMGa's set up in the same room. Just did the crosser upgrade for the 1.7s and have about 10hrs on them.. all I can say is wow.. will be posting pics and a write up soon..
Get the 1.7 .. upgrade the crossovers and you'll be very happy you did.
