I have some older spatials, never wanted for bass at all. I think the ear-brain needs burn in time to fully appreciate the difference in sound, especially the bass region. Was watching a a movie the other night and appreciating the bass response and realized my sub wasn’t even on.
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 ?
