I’m in the process of rebuilding my home theater. Decided to try installing a tactile transducer/ “bass shaker” inside my recliner. I’m running it off an old sub amp and have it crossed it over at 80hz. So basically when you have it on, it shakes the chair during explosions and other low frequency effects. Thought it would be relatively worthless to mildly entertaining, but I’m pretty impressed. Pretty cheap too…about $ 70. Anybody running these?
