Focal vs Dali speakers

neither the focals or the dali are notable for their low end--if you want a full range speaker you'll need a sub, or else look at other models. that said, i'm a big fan of the focals, which are incredibly transparent and sound good with modest amplification. in lieu of the floorstander, you might consider a monitor + sub, which will give you bigger sound for about the same dough.

Large room? Neither of those will put out much of what you are looking for. Loomis makes a good point about adding a sub in your situation. I would go for the FOCALS if adding a sub. If you dont want to add a sub, look at something different all-together. How big is the room?

as i should have indicated before, i'd actually opt for the focal cobalt (now discontinued, but widely available used for cheap) or electra, which have more seamless driver integration than the chorus.

the room is 600 ft, its large to me.

thats not large Bobrock. Still, a sub will benefit the situation. Though, placement will be important. You can probably experiment and get adequate bass performance. Try that, then see if you need a sub.
