Well done Jim! I'm still at "bodger" level when it comes to room treatment. I have a thick rug sitting in front of my ported Tannoy 15" MG cabinets and two large accoustic panels sitting directly opposite the main driver in the Tannoy cabinets. I also have two very very rough corner traps. I've not moved things around, as I can't! I don't have the space. Any new accoustic treatment would probably be on the ceiling, behind the speakers or maybe more side panels. Things sound very good already but I suppose things could always sound better.
