Pretty sure that ship has sailed. The OP asked the question seven years go. But as long as we're on the subject almost all speakers have way too much filling inside. Most speakers sound much better with the bare minimum fiberfill, wool, what have you. Besides, Beaks aren't really mass loading, as it turns out. They are a point where resonance can escape the cabinets.
TOTEM Sttaf removing mass loading
I am considering the purchase of a totem sttaf. They have been loaded with kitty litter by the owner. The owner says this makes shipping difficult, and even if removed there could be problems caused by left over kitty litter moving around in there. This worries me, I would like to be able to remove all of it and have an unbiased speaker. Does anyone have experience with removing mass loading from a Totem Sttaf speaker? Please explain how to remove mass loading. Please also explain if you believe that if you remove the mass it is safe to ship. Thanks.
