ML Rear Suggestions

[jaramill]

I'm a new ML owner and looking for suggestions for rear speakers to match my fronts.

Current setup is

Electro-Motion Series:

1. ESL [front left]
2. C2 [front center]
3. ESL [front right]
4. Dynamo series: 700 [sub-woofer]

That's a 3.1 setup. Thinking about going to a 5.1 or 5.2. Suggestions for the rears that I've been looking at are:

Motion Series:

1. 2
2. 4
3. FX
4. LX16

or
Electro-Motion Series:

1. FX2

Plus another sub-woofer (Dynamo 700). My A/V receiver is the Marantz SR7005. This HTS setup is in my living room whose dimensions are ~2k cubic ft @~10(H)x14(W)x14(L). The right side of the living room is open that leads to the rest of the apt (i.e. entrance, kitchen, dining room). Left side has window w/vertical blinds, and the sofa is an L-sectional up against the back and wall and to the left by the window. So I have no room behind the sectional.

Thanks.
