@ Carl & MacGuy & Crion, would you mind / be able to provide your rough room dimensions and the speaker distances from the walls ?
I'd be particularly interested - and perhaps others would be too - at the distances that are "happily" accommodated by the various Meridian speakers in differing set-ups.
Thanks !
