I have 4 A'Diva's and use a Due as my center speaker. I cannot say enough good about them. They work as a home theater, they work for music listeneing. If you buy an ADiva you won't be a bit sorry.
First, the sound great. I haven't noticed any tinniness. They do require a subwoofer however. Gallo sells matching subwoofers. The TI is supposedly even better sounding.
Second, they look great. They have a bauhaus style which complements good furniture. Speakers are typically just big ugly boxes. Not everyone wants a pair of coffins in their living room...
I haven't heard the new Micro TI.
There is Gallo website, but if you email questions or comments don't expect a reply. They really expect you to use their (less than extensive) dealer network.
