Point of interest your profile does not mention DSP6K's but M60's so a little bit confused.

If I'm to assume the M60's have been upgraded to DSP6K's you have exactly the same system as I had albeit with a Velodyne Sub. Co-incidently my listening space is very similar @ 5.4m x 3.2m.

I found at the time that listening to stereo on the 6'ks was fine but 5.1 material was uncontrollably bassy.

Personally, I would go down a route of upgrading the main pair to 7.2 or 8's which I have done then adding a bass DSW.

Our good friends Steve & SWPNT also aided my journey.

Cheers
