klh yes room acoustics but more specifically, speaker interactions with floors. Especially suspended plywood floors but most any with any give. Floors often ring like a bell at bass frequencies and speakers transmit a lot of energy to them directly via physical contact if not isolated. If flooring is not solid concrete foundation, isolate your speakers from them first and go from there if still needed.
Whart yes all recordings are different but room acoustics in general will greatly affect most still even when the "proper" bass is not there. I say proper with reservations because its up to the recording producers to determine what goes into each recording. So you want to reproduce what is or is not there accurately. Trying to make recordings sound like something they are not is public enemy #1 in regards to staying on the hifi merry go round forever.
