Most often, the shake is contained within the room shaken, with very small, if any, amounts of the energy being transferred throughout the rest of the house.
Foundations and other supports under a floating floor absorb energy into the earth. Walls built on top of the floor greatly dampen the shake, but also can transmit the remaining energy into the rest of the house.
When using the ButtKicker, subwoofer volume levels can be greatly reduced and you will still feel powerful bass. This helps keep sound energy from bleeding into the rest of the house, or worse, your neighbor's.
We've had a wife come up to us to say "I love that thing, even though I never even go into the theater room!" With further questioning, we found out that she "could now read her books in another part of the house without the "boom, boom" from the theater room distracting her."
Yes! The isolators will not only maximize the effect of ButtKicker transducer, they are also important to support and level your couch and to make sure that the effect is contained within the couch.
Why, yes there is! Of course, different people like different things. The simplest and most basic setup (as suggested in the User's Manual) is to feed the ButtKicker brand transducer with the subwoofer output of your surround processor.
Some also like to add to this signal the front left and right signal, because of the emotional, low frequency content of many musical scores. A simple and effective mixer is available for this function, though any line level audio mixer would work.
Some people want greater control over the frequency spectrum sent to the ButtKicker transducer by adding a variable crossover in line. The subwoofer output of your surround system will have an upper limit of 120 Hz, but a few users have chosen to limit shaking frequencies to 40-80 Hz.
A sub-harmonic generator can also be inserted in line. This device would pass the original signal through to the ButtKicker transducer while adding lower, "sub" harmonics to that signal. This increases the amount of low frequency (LF) content in the program, but keeps it related (harmonically) to the original program material. This can be helpful with older movies and games that had little or no LF information. Could you simply raise the low frequencies with an EQ? Only if that LF material is there to begin with; if the material is not there, you would only raise the noise level. A sub-harmonic generator, on the other hand, adds new LF material to the original. One of these devices was mentioned in the Secrets of Home Theater and High Fidelity review.
