Open baffle sonic benefits do not surpass boxed speaker designs from engineers who know their stuff.
Open baffle is much easier/cheaper to design/build. Even incompetent dudes with an open baffle offering can claim they are good at designing speakers. On the same note, If someone’s getting greedy/ trying to overcharge you for it (could name a few), have a second thought about it.
They are a bit restrictive on your choice of subwoofer. But, inclusion/correct integration of subs is a necessity for openbaffle.
They are much more room/placement sensitive. If you have a bad room or restrictions for optimal placement (atleast 80+% of guys on audio forums), try and stay away from it.
