Thanks to you both.
Don - the Arro speakers have a bottom port that is mass loaded by adding clean play sand, silica sand, or odor-less kitty litter to them. The manual says you may not need anything and suggests adding a little at a time.
See http://totemacoustic.com/pdf/manuals/Totem_UserManual.pdf
The Totem website suggests between 10 and 20 lbs. for the Arro model. Some other models are suggested to use less. See http://totemacoustic.com/en/support/
