Open baffle speakers

Open baffle sonic benefits do not surpass boxed speaker designs from engineers who know their stuff.

Two different sonic presentation, nothing to do box speaker designers knowing 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.

Tell that to Linkwitz.  Just as many, if not more, incompetent dudes design box speakers.  

They are a bit restrictive on your choice of subwoofer. But, inclusion/correct integration of subs is a necessity for openbaffle.

Correct integration is required for a box speaker as well.

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.

To get the best performance from any speaker room placement is important.  80% of guys on audio forums are not nearly as knowledgeable as they pretend.  Use of that percentage to support "stay away" is meaningless.

A Ripole subwoofer does a remarkable job for its size.  Borrensen, pretty competent dudes, now offer their version of a Ripole.  

Boils down to preference, no right or wrong.  Experiment and you could be pleasantly surprised.

But, give me 3 hours and I'll build you a open baffle speaker in my garage and the sound of it will get you jawdropped. I already know which pro drivers to use and how to build your crossover. I'll charge 20k just for kicks and laugh all the way to China town.

What are you waiting for?  Do it and quit ragging on those that produce a product.  For just an audio enthusiast you imply knowing quite a bit about designing speakers and cables.  Seem like you are sitting on an untapped gold mine of expertise.

Coke vs. Pepsi.  There is no right or wrong.  Neither type of speaker is unquestionably technically superior.  In my limited experience with a small number or audio enthusiasts, a majority moved to open baffle from box speakers.  All described a more musical presentation closer to live.  All described an evolution away from brand name hype, reviews always positive, focus on specs, and a maturing of  their tastes.  All wished they had discovered open baffle sooner.  I know other enthusiasts that love box speakers.  Listen to what you like.

The OPs "But more listener prefer traditional loudspeaker design" attempt to claim being right and have the last word is meaningless.
