I have the GR Research NX-Otica open baffles and their 2-driver OB sub. Most of the people in our audio club rate them as among the best they have ever heard.
There’s certainly excellent bass. Very tight and textured.
Open baffle speakers
Open baffle speakers design is the simplest , to get bass response similar to other design , like ported, the baffle size must be huge to avoid low frequency degradations . Tipical size the baffle width 10-20" got weak bass performance. I am wondering how open baffle speakers design became so popular ?
