Let go of the music

When auditioning box speakers I find myself paying attention to how the speakers release the music. Every cabinet has a point where the music flows. The point right before that is sometimes vibration, as in a box, like a guitar, or my favorite lately flow from a very inert cabinet, like a solid monitor. I’m enjoying the imaging and presentation of this inert approach in pinpoint imaging, but have come to appreciate them all.Can anyone expand this position on cabinet design that in essence forms the image, or wall of sound? I know the room and electronics cables etc play a role but the speaker is the strongest factor in sound reproduction. I don’t care if you think one is right or wrong so no need to take over my living room. Boxless crowd welcome.
