Help with speaker placement

[cjsiv]

So I have been doing some research and can't seem to come to a conclusion. Any input is appreciated. I was previously running a 6.1 setup (latest codes a few years ago when I finished my basement). I just purchased a set of dipole surrounds and now I have a few different options. Here's my specs:

The room is roughly 18x12. I have a Jamo A330 setup consisting of 4 sats with a larger Jamo E center. I just purchased a set of Jamo C400 dipole surrounds to complete the 7.1 setup. I drive them with a Denon 1910 which does matrix to 7.1. When the room was finished off, I ran wiring for a front L/R/C and a rear L/R/C on the opposite wall. I have seen several placement diagrams and some show the surround speakers to the side, and some behind the listening position. I have a drop ceiling so running new wiring isn't a big deal. My questions are:

1. Do I go with 7.1 or Dolby IIz with height. I have read the cnet article. Sound&Vision kinda liked Dolby IIz. Any input?

2. Which positions do I give to the sats (surr or back) and dipoles (surr or back)?

3. If I move the sats to the front for dolby z, do I leave the dipoles behind the listening position or move them to the sides.

4. Is my room too small to run 7.1? Will the discrete channels start to run together?

I'm trying to get some input so I'm not mounting and unmounting speakers all over my walls. If this were your setup, what would be your preferred placement?

I’d have no problem implementing a 7.1 setup of one form or another in a room that size. Whether you go heights or rears is up to you, but the surrounds, being dipoles, should be placed directly to the sides of your listening position.

It’s a tough call of which way to go. With your small sats, it may be beneficial to go with the heights as opposed to the rears. Assuming you’re looking at the 12’ wall, if you go with rears I’d place them about 6’ apart.

Tried out Dolby IIz. Didn't really notice anything. Opted for the standard 7.1 setup with the dipoles on the sides. Thanks.

A photo of the room/setup would help us help you.

IMO i wouldnt use PLIIz unless i was going to put the height channels in my ceiling. i honestly think we are getting a bit happy with the channels, IMO the only way PLIIz would be of any use, is if you had 2 channels in your ceiling placed in the middle of the room. or maybe i dont know what im talking about....again
