Biggest Sound in the Littliest Box


Can some one suggest speakers that offers the "big speaker" sound in the smallest box? For me, price is not a big factor (to some extent) but space is.

Thank you everyone for your inputs. There are some very good suggestions. I guess I should have made my question a little clearer. My current speakers are the Dynaudio 3.3. I want to stay with about the same size but I am looking for bigger sound, like the one you can find from speakers like Wilson Slam, Nearfield Acoustics, Wisdom Audio, and etc. Is this achievable or the law of physical doesn't allow for such things. You can suspect that I like to listen to my music loud.
Spendors are legendary for having a vast,open, soundstage...they really do have a deep, spacious quality to them...maybe not the best for extremely loud listening...but I would opt for accuracy and transparency over volume...they are one of the few box speakers that can compete with planars and stats...and they dont sound thin in the midrange....
what are you using as for an amp? The 3.3's will sound huge when you throw enough power at them.
Poorguy, B&W 805s are not my speakers for life, BUUUTTTT, that said, these diminutive units reward every upgrade I make. All the components in my system cost 2-3 times more than these speakers, including my cables.

With the right front end they are capable of BIG, detailed, harmonically rich orchestral sound. However, beware the front end that isn't up to the task.
