Can't comment on those specific models, but in many cases most speakers perform considerably better a bit away from any room boundary, period, purely for the sake of imaging and that 'airy' presence in the soundfield. Naturally, this can depend on several issues. Most of us without dedicated rooms are often forced to compromise with multi-channel set-up's however. Then there are of course some speaker configurations that are constructed to be placed near a wall to perform at their best.
But the same could be said about most speakers, even those that have been designed for boundary use. Give any speaker a bit of room and they'll sound better. Maybe the LS50's at the side of me are ok because they have clean output. I don't know, but they work.

There isn't a dedicated bracket for them, and you won't be able to use brackets that grip the bottom of the cabinet because its all curves and no corners. They're quite heavy too, so I'd recommend putting up a shelf for them.
Speakers desinged to sit close to a wall are not immune to sonic reflections. All speakers are effected one way or the other.
My CM1's are mounted on the side wall, yet I can clearly hear sounds directly behind my head. Good amplification helps with this, but there is no issue with the imaging in this case.

Apart from perhaps a few slimline speaker models I've heard (Def Tech, KEF, Opus). I was at a demo of a bunch of these which could be placed either on table-top stands or on walls. During the test the wall mounted ones sounded better both in terms of imaging and 'fullness' due to the close proximity to the wall. On table-top stands I thought the imaging came off as a tad diffuse, lacking focus. But those kind of speakers must surely be the odd exception in some cases I suppose?

When I say speakers that have been designed to work close to a wall, I'm referring to the likes of normal hi-fi speakers that have a decent cabinet volume. Flat speakers like PMC Wafers and KEF T series which have been designed to be used mounted ON a wall will sound better against a wall.
With demonstrations like these, you have to take into account that preference will be given to the product that is being promoted - so chances are any normal rear ported speakers were probably used without bungs to exaggerate the difference. I don't know the specifics of that demo so I can't really comment in depth about it.
i meant that the LS 50's were in a 5.0 configuration with the .1 being the DXD12012. I know what I mean anyway ha ha.

For similar money to 5 of the LS50 you can get the MA GX's.
I would like to hear them against the Kef's as a direct comparison

How about a combination, apex as rears and kefs as fronts, with the center being either another ls50 or the apex a40?

The Kef LS50 speakers are lovely. I use them for fronts and rears. Centre being an XQ50c and the subwoofer being an MA FB212 (not for the fainthearted). There is no need for me to upgrade beyond this set up. I worked up through the Kef Eggs back to Kef Q10's and when the Kef LS50's came out then I jumped at them. Electronics being Arcam FMJ AV9 and 3x P35 Amplifiers. Its a nice set up. If you plump for the Kef LS50's you wont be disappointed.
