Hi Hiep-
My personal opinion on Community: they are a great company that builds product in a range of price points, with matching audio quality. I started using their horns 30 years ago, they simply sounded better.
I don't see Community's lack of a 'line array' to be a deficit. Bruce Howze is concentrating on things that make money, reliably, for his company. That's smart business.
They do well with the install and commercial market (having very good products helps). That market is driven by sound, *engineering* and cost. Community's products do what is claimed and tend to be rugged and reliable (some insanely so).
In the MI market, things are driven by often unreliable "specs" and price. Community still puts out real-world numbers for their products at this level.
At the pro "system" level, they simply haven't figured out how to successfully impact the people that use and purchase entire systems.
Before the T-Class, there was the AirForce. An interesting and good sounding design that was clean and loud. Very Loud. LOUD. It was impressive... the "mid-throw" top box delivered out past 100m. Almost zero power compression. There was some interest from US touring companies, but Community never built a full, stadium-sized demo rig for them to play with. Also, this was about the time the "line array" was coming into play. It takes a huge amount of money to play at this level, and I suspect that somewhere in the process, management figured it was cheaper to write off the R&D than to gamble additional money on demo product and all that goes with it. Also, at this level, an Artist Engineer has to want the rig, too, so there was this previously unknown (and non-purchasing) "client" in the stew that Community had never needed to market to before. It's got to be a lot harder than selling weather-resistant speakers for installs...
Whether or not this happened with the T-Class, I have no idea as my "insider" doesn't work there anymore.
Have fun, good luck, and don't buy a line array if you don't NEED one.
