E-mailed PSB and they said I can use SP-25I stands but I cannot seem to find these stands anywhere. Speakers are 12 3/4 x 13 x 7 3/8" and weigh about 18 lbs each. Anyone know where I can either find the SP-25I stands or know of stands that would work? I have small children so I'm hoping to find something sturdy enough to be able to stand up against an accidental bump.
