Ignore just test

[xandra]

Here's a rough diagram of my setup:
Not shown:
curtains which run along windows on left side
The room has cathedral ceilings (with apex running along dashed horizontal line)
Need some advice on this

THE Biggest prob: Surrounds:
1. where to put Surrounds (my primary concern is music, not HT)
2. would I be better off going with FXi's for surrounds? seem they would 'radiate' sound better given awkward locale...
BUT a polk phone techie had told me these only function properly when attached to wall (not possible since one speaker will definitely run along a window)

All ideas appreciated.
