I used to have a pair of their Reference 3 speakers and they sounded amazing, and reasonably priced (for high end audio.)
These probably sound absurd incredible.
Those have got nothing on my 5' Magnpane Speakers...
I am sure they'll have something to say about mid-to-low bass response. Maggies are nice, but if you don't have a high current amplifier and at least 3-4 feet of separation from the back wall, Maggies suck air.
CDT makes some fine fine drivers, so combined with the legendary Gallo sound, this speaker should sound great.
Nor to my Bozak 305's. Apples and oranges, my friend!
Thanks for the explanation of the phase issue with multiple drivers below...good stuff.
DAMMMMNNNN SOOONNNN
took me a couple of minutes to count all those drivers, woofers, and tweeters.
I don't really know anything about acoustic theory... but it would seem to me splitting up frequencies on more drivers would clean up your sound. Hence why a "full range" speaker almost always sounds like shite.
Charlie:
Not necessarily...Granted, you can not expect a single 5" or 15" driver to reproduce the entire sound spectrum but in some regards less is more.
Some of the best sounding systems I have heard have been very simple. Why? Phase coherence. When you have multiple drivers in a system, it becomes more difficult to keep them time aligned properly. It can be done but it is generally more hassle than it is worth for anything other than large sound reinforcement systems.
It looks like these units (although essentially a 3 way system) are functioning as a line array where a number of smaller drivers couple closely together in order to minimize problems with phase coherence.
Shane:
Another leading hypothesis for why full-range speakers may have a 'special sound' is the lack of certain time-domain artifacts introduced by crossover filters.
In this case, his goal is apparently to approximate a line source, which minimizes interaction with floors and ceilings, allowing a more pronounced stereo effect (more like headphones), as well as more even volume levels throughout a room (sound pressure falls off linearly rather than quadratically with respect to distance from the speaker). Another prominent example of this approach is the Bose Cylindrical Radiator (PA/monitor system for live music).

I want these! how much?! I don't have room for them but I want them anyway!
You don't have 6.5' high ceilings? Ouch. Are you a hobbit?
haha.. there is no room for floor standing speakers next to my TV... to the left of my TV is the front door... to the right is the fire place... i only have room for small satelite speakers if anything...
Build your own man! I've built over 20 pairs of speakers with great results. To replicate this design, you'd be better off using the front array with a separate 15" sub (A 15" subwoofer has more area than those twelve 4" units, so will produce better bass).
Post it on the parts express forum and ask for help, lots of experienced guys there who'll steer you in the right direction:

Wow, speakers as tall as me? Anthony Gallo must be compensating for something...
. . . says the person who feels the need to "casually" mention his own height.
... and have a screen name referencing his size
Why does this get news but not av123's own line source speakers (LS-6 and LS-9)?

Oops I thought I could use HTML code for the link. My bad.

I think the technology and design aspect in the Gallos is much more interesting than AV123s high value, but frankly boring (to me) style.
That said, I currently own AV123 Reference speakers and love them. A lot.
Right, because no one earns their own money anymore.
Cool, but what's the enclosure made of? Surely not flimsy acrylic..

pj fgs. dont compare bose to gallo
Almost 2 meters tall? Damn, that's taller than me :)
Looks pretty sweet otherwise too.
Nice design, but there are several flaws.
Firstly, using twelve smaller 4" "subwoofers" is a bad idea and unnecessary. A low distortion 15" driver has 20% more surface area than those twelve speakers combined and will be able to play louder and cleaner.
Secondly, when you do an array system, you want as little distance between the tweeters as possible, because high frequency sounds are directional and if placed too far apart they will create a "comb" pattern in the audio, which you will hear when you move your head from side to side. The correct placement would be to put all the midrange drivers as close together in a line as possible, and then directly to the right or left side of that line, put all the tweeters as close as possible in a line.
