ButtKicker Advance BK4-4 4-Ohms Low Frequency Transducer

These work great for my vibroaucostic table.

It works as expected, but I wish I could crank it up to around 400W sustained without overheating protection kicking in.Bolted it to my IKEA Markus chair with a thin wooden board.I use it mostly for flight sims in VR, really adds a lot to the experience especially with software that works seperatly from the game's audio using the game's telemetry and allows you to customise the gain and sound file of each effect.I've used it for music with headphones as well and it does the job well enough for the low end.In flight sims it does overheat especially with sustained engine rpm effects and the like which takes around 10min wait for the transducer to be usable again with active cooling.It took me a while to find a compromise that works between setting the gain for certain effects and lowering my amp's gain to around 200W. With a fan it can be pushed higher.It is plenty powerful at around 200W, but I do love the tactile feedback at higher gains and wish I could push it higher without overheating after 30min of playtime.

this is my second device that is now combining with the other under my couch which is wired in series.Which now gives full range when they both work together. Its nice effect.Subs give airborne flow in the air while buttkicker gives the sense of feeling whats going to happen with very low frequencies. Its like someone is standing waiting for a train coming and your body is sensing with that emotion that its coming. I can see how these products came about ,with now theres motion code.But this product is a nice start for something opitional to have . Its worth buying.

I'm still experimenting with it in regards to power amps, and understanding the low impedance requirements. Info should give a better idea of usable amps, etc
