The wave energy from the back of the drivers can not be destroyed. An example of how this will affect the sound…..If the cabinet has an area that is 100 times larger then the driver then if it vibrates at only 100th as much the sound coming from the cabinet will be equal to the sound from the front of the driver.
Just how much do speakers suppose to vibrate?
I have a pair of Totem Staff speakers and when I play music with some bass content I can feel the top of the speakers vibrating to some degree. I like the sound of the speakers and I just wonder if the speakers suppose to vibrate this way. I do not play music very loud (around 85 dB peaks) and yes I tried stuffing the lower chamber with sand, but I did not like the result. Also I tried putting some iron weights over the top of the speakers and the vibrations lessen about half (this according with a vibrometer app for android). According to the vibrometer the vibrations go as high as IV in the Modified Mercalli Intensity Scale. Is this level of vibrations normal for this speakers? Also I should mention that the speakers are spiked directly to the floor which is compose of tiles over concrete.
