Not ideal placement I'll admit, but once we move I'll be able to do something about that. The stands made a big difference to just having L/R on the floor. Thanks to everyone here for all the advice in getting me this far!
Would love to centralise it a bit more, but right now there's a sub behind there and a mess of wiring. We're renting for now until we buy later this year so I've already put my requirements on the list for proper separation, wall mounting the TV, add extra sockets etc.
