what makes the clock tick in this question? makes me go hmm..
i just got this incredible 1000watt home theater system and the subwoofer makes the house shake...literaly. i can feel it on the walls five rooms away. i wana know how how it does that.

a huge magnet

a good stiff poly driver

only low freqeuncys are sent to the subwoofer

self powered have more punch than passive ones

porting on the subs help put out even more bass

cabinet size is a factor

padding is as well

cabinet construction helps deaden reverberation ( buzz )

bi amplification also helps

a good receiver with good reserve as subs take up enormous amounts of peak power whne a good critical passage plays

It does this because of two things:

1. The larger driver (woofer) in the sub moves more air each time the driver goes back & forth, than does a smaller speaker driver. Movement of higher volumes of air at lower frequencies is what gives you the lower notes.

2. A crossover built into your speaker system is like a traffic cop that tells any audio signals except very low frequencies to go to other speakers. This means that the sub can "specialize" in only low frequencies. IF your sub is too boomy, you can adjust it on the sub itself, or via the frequency controls on your reciever. You wan the bass to be tight and resalistic, not boomy or buzzy. Enjoy!

there is not any such element as a unmarried wavelength (or frequency) of red (pink-violet) mild. red is a mixture of lengthy-wavelength (low-frequency) pink mild and short-wavelength (extreme-frequency) blue and violet mild, with little or no longer some thing contained in the medium-frequency yellows and vegetables. also, there is not any such element as a real pink mild. The longest wavelengths are actual extra like scarlet, which has a tendency fairly in the route of the yellow end. real pink pigments, like mild, can be a mixture of the acute extreme and low frequencies of the seen spectrum, yet purely fairly the extreme-frequency stuff. real pink pigments or dyes mirror (or transmit) both lengthy-wavelength and short-wavelength mild. The "pink" ink utilized in complete-colour printing merely isn't pink; it really is magenta that absorbs purely mild contained in the midst of the seen spectrum and transmits or reflects the stuff at both end. at the same time as mixed with cyan (the "blue" ink that actual has a tendency in the route of eco-friendly and passes both eco-friendly and blue mild) the right result's a gloomy blue, tending strongly in the route of violet. The cyan ink absorbs the decrease-frequency reds and oranges and the magenta absorbs the middle-frequency vegetables, leaving you with purely the extreme-frequency blues and violets.
