We are talking about loudspeakers on stands.

Hi.

Please stick to the topic.

Any loudspeaker system designed to perform OFF the floor need its base stand free air flowing as if it was still off the floor.

This is how such off-floor speakers are designed, built & tested in the anechoic chamber. To allow the loudspeaker to work at home to reproduce close to such ideal non-reflective envirnonment it is designed, care must be taken to allow free air flow from all direction, that includes the base stand.

Ideally, the loudspeaker should be lifted in the air off the floor.
But realistically it cannot be done. So a acoustically transparent base stand should be used as much as possible to provide free air flowing under the loudspeaker box.

That's why any box shaped base stand is not recommended. FYI, my bookshelf loudspeaker are placed on strong tripod-shaped steel
stand on strong steel spikes, with the voids inside the tubular legs jam-packed with lead shots & sands. Very fine sands are there to fill up the voids in btween the lead shots to prevent lead shots from moving inside the stand legs.

The stands are pretty much acoustically transparent, & pretty immune to acoustical feedback & structural vibration from the floor below due to its added mass & isolation via the steel leg spikes.

More on floor standing loudspeakers later.
