As wise as ever Rodney on all things bass. You could re-name yourself bass-meister!

Wondering about fitting 2 subs in our new room & I'm not sure where they'd go. The front wall in 4.7m but the screen is just over 3m wide & I want it between the front speakers, not above, so by the time I have 2 5500s either side of it that doesn't leave much space there. It might just about be ok for medium sized ones. To the right of the sofa is fine but the left could be a bit obstructive for a decent sized sub. One option is on the back wall where there'll be plenty of space; would subs work there? Or is it possible to mix subs; one large to the right and a smaller one elsewhere? Or do they ideally need to be a matched pair and in mirror locations?
