I've always thought that open baffle and planar/ribbon speakers have a sound that either attracts you or not. It is an open transparent sound that got me instantly. I am very happy with my Spatial Audio Lab X5s which I consider my endgame speakers.
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 ?
