Question: frequency response?
Document: If you have a home theater, mount a pair or two of these in your coach. You will be able to lower the volume of your sub (ie. save your hearing) while still feeling the rumbling we all crave. Using a parametric eq to smooth the frequency response, especially the 40hz resonance peak, will make these a great addition to any theater.
I ordered this to fill out the very-low end on my home theater. I've got a great component built system and speakers, and my subwoofer is well matched for my system between crossover and frequency response. The inclusion of this on the LFE channel is astounding though. After trying several mounting locations in the couch, i wound up putting it low on the main frame facing out. This makes the induced vibrations travel horizontally across the entire couch, which benefits everyone.
I have no words to describe how this worksSo if I say It's a tremendous feeling as improving the low frequency for the music and especially the gameUntil we have some do not know what you get lostVery very GOOD :)
The seat  will shake mildly  as you drive and brake and significantly as you drive over the rumble strips. If you want the rumbling to be more frequent, you can turn the frequency dial on the Dayton up a little and it will trigger on slightly higher frequencies too- like the engine noise. The problem with doing this is that at the beginning of a race you will feel the rumble of not just your own car's engine but that of the neighboring ones too.
These are significantly cheaper and have a real fun factor when you feel a dubstep sine wave sweep through your bottom. Even cranked up loud...loud enough to really give you a strong sense of low frequency, even without a sub connected, you can barely hear them outside the car. Bass for the discerning and conscientious mobile basshead!
which is revealed in this video about the practically unknown Bosnian Pyramids[...]7.83Hz is magical, and necessary for life
this is a great product. i mounted it under my bed and it does a great job of shaking it. this bass shaker is subtle though. if you want a shaker with more kick i suggest the buttkicker bass shaker.if you want a low cost but decent bass shaker this is the product for you. i love it!
so for around 250 bucks you will be the envy of all your friends.the other benefit is if you live in an apartment  you can keep your bass turned down on your subwoofer. because what you feel with these makes up for what you hear.I can not recommend these enough. run don't walk to hook these up if you love watching movies.
i was a little worried about these not being strong enough for my home theater but they work perfect. they blend in well with the sub and like others have stated are an excellent upgrade to any home theater.these feel as though you just have a great sub system and cant really tell that its the chair vibrating. i would have given 5 stars but one out of two was defective and had to return.
i installed 2 in the couch. its fun to jack up the amp and turn on a movie have ppl ask... is there a speaker in the couch??? i felt it move.
Answer: Probably depends more on the amp. But I wouldn't be using it for much over 200, I see some use filters to block the higher frequencies but I split my low frequency signal
