I bought a nice little 50inch plasma from a guy here on AVforums, and after sorting out a flickering issue, am enjoying it very much. As I'm deaf, I usually watch films with the sound on mute, but I miss the thump thump of big bass audio (don't want to piss off the neighbours) from the cinema. I've just found out about buttshakers / tactile transducers, and been doing some reading, but am lost by all the talk of amps, audio filters etc - it's a foreign country to me, as I've never had a need for a music system of any kind. Also, most of the buttshaker reviews seem to date back to 2012 or so, surely newer and better things are around now? Could nice people here give me some buying / setting up advice? Budget: around £100 to test the waters, maybe more for a good setup. TV: Panasonic P50ST60B (also use a Windows 10 mini-ITX box connected to the TV for gaming via Steam.) Room: Living room with wooden floor and bay window. Ground floor, couple of feet of space underneath, 1930s semi-detached house. TV is on wall shared with neighbour. We watch sitting on a 3-person sofa. Happy to open up sofa for DIY mounting etc. Would like subtle vibrations from people talking, bigger thumps from explosions & FX, wooshes etc, and rumbling from games / driving sims etc. I dunno how sofa shakers are connected to the TV. Wireless would be more wife-friendly, which is a factor here.
