I did the recordings of the Stereo-sound with these settings:
Speaker-front: Bowers & Wilkins 801 Matrix Series 2
Sub-front 1: 1 x SVS 25-31PC-Plus
Sub-front 2: 2 x SVS PB12Plus/2
Sub-EQ Sofa: Behringer DSP1124P
Sub-sofa-back: 2 x Cerwin Vega 15" XL
Sub-sofa-seat: 2 x Cerwin Vega XL-18S
Sub-sofa-puff: 1 x RH 18"
Some changes since then, and now I am using Bowers & Wilkins 801 Matrix Series 2 as surround speakers...
and they still do a very impressive job in movie-mode
