JBL S38BE Beech Studio Series Speaker Systems

Administrator: If I'm in the wrong forum, please move my post to the proper forum.

I own a pair of JBL S38BEs. I just saw a video on YouTube where the host removed the speakers from one S38 and the enclosure interior was visible. While I saw acoustic dampening material attached to the interior walls the enclosure space was empty. JBL must have thought that attaching the material only to the interior walls was sufficient. But I'm 82 and of the old school and I'm used to seeing the interior of speaker enclosures stuffed with either fiberglass or less dangerous sound absorbing material. So my question is: leave things as designed or add sound absorbing material to fill the enclosure? Second part: Would adding additional material help the bass or not? Your opinions pro or con will be appreciated.

Leave it as-is unless you have a scientifically-based reason to do otherwise. Whether one fills or lines the cabinet depends on the acoustical design; there is no universal choice.

Help the bass in what way? Is there something wrong? Again, without data/measurements/specs, why are you assuming something is amiss?
