Open Baffle vs Box

You didn't ask me specifically, but to me, OB bass surrounds you rather than punches you. This is not a quality judgement, they can both be great. In my case, where my room is less than ideal, the Spatial OB sound works better than box; though it feels like less bass, it sounds like better bass.

thank you. I appreciate your input. It was
Described to me before that you ”get the punch but not the rumble”. do you agree with that description?

Above 100 Hz open baffle speakers can be great given the right drivers. It is much easier to build a plate that does not add colorations than a box.
All of my favorite speakers, the ones that I would own are boxless. Under 100 Hz is a different story. The problem is that building a SOTA subwoofer is an expensive and difficult task and the end result will be a device that is very heavy and expensive to ship. Most manufacturers cut corners resulting in flaws that for those of us who have experienced the best bass find intolerable. I believe those of us with DIY capability can actually do a better job than most manufacturers but in forms that could not be competitively priced. 

I own several dipole speakers one pair being the Spatial Audio M3 Turbo S.. I think “punch without the rumble” is a decent way to describe some of what good open baffles do. They remind me of my Maggie’s in some ways but with significantly more punch. 
NO RUMBLE...

Thanks.  that what my dilemma is with the Spatials. I live in an apartment so subs are not advisable but it seems to be the only way when dealing with music that has lots going on below say 50hz.
