Nine-year-old boys typically spend their free time playing video games, shooting baskets, riding bicycles, watching TV, and eating snacks. But when Terrence Murphy was 9, he witnessed his first dogfight. He and a friend went to the backyard of an older neighbor and watched as two dogs bit and attacked each other.
Dogfighting Campaign: www.humanesociety.org/issues /dogfighting/end_dogfighting.htmlMost new speakers are designed to be compatible with a wide range of receivers and audio amplifiers, so specifications like impedance-the measure of a speaker's resistance to electrical power flowing through it as specified in Ohms-generally aren't things you need to worry too much about. But what you should know is that an amplifier has to work harder to drive a speaker with a lower impedance rating than one with a higher rating. Say that your receiver is rated to deliver 100 watts into an 8-ohm load. If your speakers have an 8-Ohm impedance spec, then you aren't likely to encounter any problems. But if your speakers' specified impedance is 4 ohms or less, the chances for that same receiver to overheat and shut down will be increased.Front channel towers or satellite models on stands should ideally be placed equidistant from the TV's sides and about three feet out from the front wall. This setup will heighten imaging and reduce any sound-muddying room reinforcement effects. And your subwoofer should be pushed into a corner of the room to permit the sound-reinforcing effect of adjacent walls to strengthen the bass. While placement guidelines for surround speakers are less strict than those for front speakers, installing them in a high position at the sides and slightly behind the listening area will usually enhance surround sound envelopment.Online Information: The Humane Society's EndSUMMARY: THIS ARTICLE EXPLAINS HOW A TEENAGER WENT FROM THINKING DOGFIGHTING WAS COOL--AND ALMOST TURNING HIS OWN PET INTO A FIGHTING DOG--TO BECOMING AN ADVOCATE WORKING TO PROTECT DOGS AND KEEP THEM OUT OF FIGHTING PITS.�Bipolar models also radiate sound from the front and back, except that in this case both sets of drivers are wired in-phase with one another. This design allows a bipolar speaker to provide the best of both worlds: a direct-radiator's clarity and focus, and a dipole's spaciousness.alcoholThe range of audio frequencies that a speaker can reproduce is known as its frequency response. Human hearing extends from 20 Hz to 20 kHz (20,000 Hz) - a span that few models are able to cover fully. The bass frequencies at the bottom of the range (approximately 20-120 Hz) are the most difficult for a speaker to cover. Satellites don't attempt it at all, but instead pass the task off to a subwoofer - a dedicated bass speaker with drivers large enough to move the massive quantity of air needed to reproduce low frequencies. Since tower speakers usually contain one or more woofers, they generally deliver decent bass. But if you're shopping for tower speakers - especially if you plan to use one in a system where there's no subwoofer - make a point of checking the low end of its frequency response specification. And remember that not all measurements are the same. For example, the bass response of a speaker spec'd at �6 dB at 40 Hz probably won't sound as full as one that measures �3 dB at 40 Hz.Teaching point: This activity will help students understand the concept of personal responsibility. Michael Vick is an NFL quarterback who was convicted of running a dogfighting ring. The crimes Vick committed included torturing and killing dogs. Vick served his prison time and is now back playing football in the NFL. Have students research the Vick case in preparation for a debate. The debate question: Should Vick be allowed to resume his career in the NFL after having served his sentence, or does the seriousness of his crimes outweigh any right he has to play in the NFL again? Divide the class in half, and assign each group one side of the argument.To compliment a unique glass stand, you must get yourself a set of useful glass shelves. You can utilize these shelves to present an astonishing display of your audio and other multi media devices that you own. Speakers can fit perfectly well in them. They may not stand out that much but they are stunning for those who prefers a furnished appearance with the rest of your furniture. You can also place your collection of cds and dvds to give a complementing look to your nice display.The fight is the culmination of a cruel process. Training for dogfights includes having dogs run for exhausting amounts of time on a treadmill and also injecting dogs with steroids and other drugs to make them more aggressive.Terrible TrainingThe classes were part of the Humane Society's Pit Bill Training Team. "The idea is to engage the young men and their dogs," says Jeff Jenkins, lead trainer for the End Dogfighting campaign. "We teach formal obedience in a firm but fair and positive manner. We have many dogs that are remarkably well-trained."ANSWERSBut the cruelty of dogfighting was lost on Terrence. "It used to be fun to watch the dogs fight," he says. "I wanted to see which ones would lose and which ones would win."A Boy and His Dog�Placement: the final frontierpreviouslyTEST YOURSELF* Based on the fact that dogfighting was a common occurrence in Terrence's neighborhood, does it surprise you that he grew up thinking it was normal?Terrence, who lives in Chicago, Illinois, knew that people bet money on which dog would win, but that's not why he went. "I just thought it was cool," he tells Choices.�Dipolar models radiate sound from both the speaker's back and front, with the opposing driver sets wired out-of-phase with each other. This design offers a more diffuse, spacious sound than a direct-radiating model while retaining some of the latter's focused dispersion characteristics. (Dipolar models are favored for THX-certified designs specifically because of their diffuse sound, which more accurately resembles what you'd hear in a real movie theater.)never2 Terrence was -- after watching dogs fight for the first time.horrifiedReformed and Reaching OutlegalTerrence and Elmo passed the course. Their relationship changed too. "At first, Elmo used to be scared of me," Terrence says. "He would jump away. After a while, we started being friends. He listens to me better."Scan used to train dogs to fight, but stopped after he had to put down one of his favorite dogs because it was gravely injured during a fight. Scan now spends his time educating young people about the dangers of dogfighting. He told Terrence that dogfighting wasn't the right thing to do, and he invited Terrence and Elmo to join a free training class. There, Terrence would learn how to safely train his dog.Products offered by Fine Variety International is a wide variety of glass products and furniture designed to embellish the complete range of a living room.

Fortunately, Terrence was on his way to a dogfight with Elmo when he was stopped by Scan Moore of the End Dogfighting campaign sponsored by the Humane Society of the United States.Terrence turned down the offer, but a week later he was at a dogfight where he witnessed a dog owner beating his dog badly--because the dog wouldn't fight. Watching someone beat his own pet didn't sit well with Terrence. "That's when I was like, 'I'm going to change my mind,'" he says. "I decided to check up on those classes Sean was talking about."For those who prefer to keep their audio/video equipment out of sight, in-wall and in-ceiling speakers make a great alternative to regular models. Although the sound quality of in-wall and in-ceiling models is generally a notch below that of regular speakers, they can be mounted inside of cutout cavities in the walls or ceiling of your room where they won't take up any space. Both types are also designed to contain vibrations within the cabinet, so you won't have to worry about rattling the walls during action movies. Installation of in-wall and in-ceiling speakers involves running wires through the walls and/or ceiling of your home. If you're an experienced DIY type, you might be up to that task, but for most people it's best left to a custom installer.steroids�Speaker impedance and selection1. illegal; 2. excited; 3. steroid; 4. previously* Had you ever heard of dogfights before reading this article? What do you think of the idea of having two dogs fight each other?With some systems - especially those built around a large, slim rear-projection TV - finding a place to put the center channel speaker can be a problem. Although you can get by without using one, it's not recommended - center channel speakers are specifically designed to reproduce voices. You'll find that movie dialog will sound much clearer when you use them. So instead of bypassing the center speaker or using the TV's built-in speakers as a center channel substitute (a terrible option, since the tonal balance of your TV's speakers isn't likely to match that of your other speakers), look for an alternative mounting method. Speaker wall mounts make a fine option, especially with flat-panel TVs. Most TV stands also include storage shelves that can hold a small center channel speaker.1 When he first saw dogfights, Terrence says he thought they were cool. Why do you think he reacted that way?* According to Terrence, Elmo was afraid of him at first. Why do you think this was the case? What happened to change their relationship for the better?�What is frequency response, and what should I look for?Many people tend to be casual about where they put their speakers; more often than not, they get shoved into any old space where it's convenient. But speaker placement becomes crucial when setting up a home theater system. You'll want the positioning of surround sound effects in your room to correspond to what's happening on screen, and that will only happen if speakers are set up properly.
