Monitor series 2- M3

metaldrumer

hi, i´ve been searching for the specs of these speakers but i´m kind of confussed about the exact model, it says "polk audio monitor series 2" and the S/N it´s: M3 9072552, so, i guess the model m3ii it´s the second version of this one, the thing is that i can't find any specs about the m3 speakers. and they look different (compared to the m3ii), it has 6 holes for screws and 1 bass reflex port in the front, in the back it only has the spring clip terminal and a sticker with the logo and the information.
