First, is there any solid info on the differences in performance between bass shakers and "linear actators?" Also, are the long-throw hydaulic units actually used for vibration, or just movement? What is their frequency range? The frequency range for all 3 devices would be helpful. If the latter are just meant to move the couch here or there, I don't think they are relevant to this article. --Howdybob01:20, 10 June 2006 (UTC)Reply
