Thanks Steve - Saved me re-typing smile Besides, your response was far more eloquent!

Whilst the Meridian processor can correct for many things, the process is not without some acoustic "cost". Ideally it should be used only for fine tuning with minimal processing, not for trying to circumvent the laws of physics...

It is very rare to find that the ideal position for the tweeter and mid drivers is the same as the ideal positioning for bass drivers. The smaller the room, the more critical the latter is. (http://www.nutshellhifi.com/ME2txt.html scroll down)

The bass units on the 8k's are dual directional, this certainly helps in trying to even out the in-room bass response. Another advantage of the 8k's is their infinite baffle design, the bass response is achieved without the use of resonance ie ports. This enables the enclosure to behave correctly at a much lower volume level than for a ported speaker, late night listening etc.

So, if any of the "senior" Meridian speakers can be made to work in your room, the 8k's will have the best chance. BUT.. by the time you've positioned the speakers away from the rear and side walls (about 1m?) there will be precious little real estate left for the listening chair which itself needs to be away from the rear wall (behind) - unless the rear wall can be made acoustically dead.

More importantly there's very little space available for the soundwaves from each individual driver to merge together to form a credible soundstage and reproduce a point source (the theoretical ideal)

A room will have a natural bass gain of its own, and the smaller the room, the higher frequency at which this effect will commence. The following link may shed some light

I suspect in your room any speaker that naturally achieves it's -3db point below 45Hz will start to overload the room. Traditionally this is the territory for smaller infinite baffle stand mounts - driven by Meridian electronics of course wink

There are other designs too that could suit the space better - dipole speakers for example would at least allow the speaker to be placed close (5cm) to the side walls due to their "figure of 8" dispersion - though you'd have to invest in sound panels to kill the back wave... the natural room bass gain would compensate for the traditionally weak bass response of this design.

Unfortunately your room is far from ideal for music reproduction and you have many physically induced acoustic issues to overcome.

Headphones of course would avoid all of these - a pair of AKG1000's or Stax Sigmas along with a subwoofer could produce a far more satisfying listening experience - I have mentioned these models as they avoid the "inside the head" soundstaging of traditional 'phones.

From my own experience, a pair of Stax with a B&W PV1 sub proved very satisfying and acoustically outperformed my G68/M33 set-up from some years ago by some considerable margin.
