I use my MBL 111e's in an integrated Home theater/two channel music set up; and power them with the Bryston 28sst's monoblocks; much better dynamics and sound now with this extra power; then when I was using the MBL 8011's; which I thought underpowered the speakers...for theater; I use an Aerial CC5 center speaker; as I thought it would be difficult to get proper dialogue with an omni speaker for center channel duties; and it integrates great....sounds like you are on the right path; I have one Velodyne DD15 as a sub; but the MBL 111's have their own woofers; so I don't need as much extra base as you will.
