Through the Gambling Control Division, the Department of Justice regulates all forms of gambling in Montana, except for the Montana Lottery and horse racing. The legislature has charged the division with maintaining a uniform regulatory climate that is fair and free of corrupt influences.
Because the amplifier is an active electronic device, it needs power, and so you have to put any active speakers near a power outlet. For most audio systems, the subwoofer is probably going to be your only active speaker (though you can also find passive subwoofers, and some high-end audio systems use these). Thereâs no practical reason for any of your other speakers to be active.
Report Abuse. Most manufacturers of decent subwoofers design the crossover frequency to start around 250Hz. The larger the speaker cone size, the lower frequency it can reproduce without distortion. A 15â sub will go down to 20-25Hz which will reproduce the audio signal you feel more than actually hear. I wouldnât suggest purchasing any sub that will not go down to only 30Hz. If itâs not rated below 30Hz, you will miss out on some of the lower end program material including sub-harmonics. RudeKarma Â· 9 years ago.
