Was hoping somebody on here had some experience with using them to share whether they are worth picking up and to answer questions because I really no jack squat about these things.\n\nI have an Emotiva 2 channel amp just sitting in the closet. Wasn’t sure if I should buy a bundle that comes with an amp or just buy the shakers and use the amp I already have? I also am unsure if they are just kinda plug and play or if they will require a lot of tuning to match them up with the subs? Plus with having 2 subs already do I split those 2 subs off of one sub input on my AVR and add the shaker to the other. Or split the shaker with one of the subs? Can I still reliably use Audyssey? Or do I need a mini dsp?\n\nI am watching some videos to try and figure it all out as I post this. I appreciate the responses.\n\nI can't remember which brand I bought, but they were fairly cheap and came with their own amp. They worked really well and added a certain sense of realism to watching movies, but the fan on the amp was very loud and distracting, so I stopped using them. I also had an extra receiver lying around at the time, but unless somebody can tell me how to do, you would almost need two receivers, one to separate out the bass signal, and one to amplify the signal. Although, could feed the sub preouts back into an 2 channel input and do it that way? Maybe there is a way, it just got more complicated than what it was worth, but it was pretty cool when I did have them attached to the couch.
