Biggest Sound in the Littliest Box

I would bet that if someone could build a smalle speaker cabinet to house a dynaudio Essotar 330 tweeter and high end 4" driver, and integrate a proper crossover(challenging?), you'd have HUGE SOUNDING MONITORS when mated with some well set up good bass woofer(s)!!!

You know Bose has made a killing with their rather aweful sounding but cleverly engineered an marketed "cube" systems over the years. I know that set up appeals to many who want to get the gear out of the sight lines, and ditch the idea of boxes on the floor also. I've heard the likes of Gallo's and even Ergo's, and those seem to go in the right dirrection, if not being perfect sounding. Still, the Ergo's are a great product IMO.
I wish Thiel would do something small like those or the Gallo's, using their tremendously good sounding mid/tweet coax driver they use in their 2.4 speakers!!!!...only let it play down to about 125hz at least! Then, you could get a fast little sub to mate with em! If they could pull that off, the sound surely could potentially be the best sounding little speaker offering out there, ya think?
Now I know there's more to making great souding speaks than just using good parts. But I can't imagine why that wouldn't be possible! Infact, marketed properly, if the design was a success, I would think they could rule the speaker market for years to come!

"Big speaker sound?" Hummmm...that one might have to be quantified more for me. If you're refering to a bigger speaker as sounding more"full, "weighty", and "authoritive" in the bass reigion, then that's one thing. I've certainly heard speakers that offer a MUCH BIGGER SOUND(potentially, considering good room acoustics and set up) in terms of soundstage, than others!(refering to pair) Infact My older SF electa Amators and MInima Amators produced a HUGE SOUNDSTAGE in a proper set up! The sound was "bigger" than what you'd get from most any speaker, regardless of size! That Dynaudio Essotar 330 tweeter produced as much detail and life as most anything I've heard!
So, when you say "big" I'm just not sure what's being infered.
Also, I'd submit that tiny speakers, even if they have better than average bass response(if that's what's being refered to), will still need a powered sub somewhere to pull off the "full range thing" properly...otherwise you've got a limited aplication monitor...if that's what you're after.(which for some applications is ok) That said, if you're after a monitor that produces a big sound(probably refering to size of soundstage) within its respective frequency response, and you add a well set up woofer somewhere,you should have some overall "big sound"!
Of the "tiny" monitors out there, I have a hard time finding "a pair" that produce a HUGE SOUNDSTAGE personally. You might consider doing multiple minimonitors in a multi channel set up for that.
