DALI Euphonia MS5 in smaller room

does anyone have any good or bad experiences with using these gigantic speakers in a "not-huge" room. it's approx 10X16X9. my currents speakers are linn akurate 242's withtwo 6.5" woofers. i'm looking for more bass. i would think that two 8" would give what i'm looking for. DALi dealers & the company say that the MS4's would be much more appropriate, but I can't see how another speaker with 2 6.5's would give more bass.

i've had very knowledgeable people tell me that they are WAAAY too big for my room. Others with DALI experience say it can work since it is a dedicated room & i can place them away from the rear wall. They would have to be around a foot & half from sidewalls & approx 6-7' apart (tweet to tweet). i have successfully used big speakers with 2 8's in a similar volume room in the past, but i'm afraid of spending the money & ending up with a bass problem. i do have lots of auralex foam & could add their traps for a relatively nominal amount. finally, are the MS5's & 4's really identical in sound except in warehouse sized rooms? i appreciate anyone's feedback or opinion! thanks...
