I have searched and read many positive experiances about the bass shakers but have yet to see any real negitive reviews. Just curious if anyone doens't reccomend them and for what reasons. Currently (and for the next few years most likely) I live in an apartment. I don't have a sub, but my mains do a good job as full range. I have a Marantz SR5200 for the 5.1 and a Kenwood stereo reciever that can be used for the bass shakers.
