In Asia, for events,occasion,parties commercial use basically which i have personally seen and heard from a lot of people that jbl spks are used more for commercial purposes at around 75% alone in the middle east and bose used for domestic use... People back in asia like the sound of jbl and say that its more durable.. unlike the case in the states,uk and european countries where they are not to fond of either.. Does jbl make better sounding spks than bose or vice versa.. or is it just a fallacy.. whats ur opinion guys.. let me know...
For commercial purposes? That has more to do with availability of product and who can give you the better price for the kind of performance you want. Sometimes it is just a matter of budget and who they know.
I like the sound of my JBL's for HT use, not too fond of how they perform for music. I am not as picky with the HT side of things, just want to be blown away with power for that. With music though, they are way to muddy and bright to even be considered for a musically weighted system. That is my 2 cents.
Bose makes excellent pro speakers. The Carrier Dome in Syracuse NY has huge Bose arrays hanging from the ceiling, and even in the highly reverberant setting, the announcements are always easy to understand. I have seen many football and basketball games there, and have sat in many different sections. Never have I missed a play.
I tend to learn toward JBL since I really like the sound of my Studio 4311 Control Monitors. I think JBL is great for the studio, but Bose is good where sound needs to be controlled more.
