To understand car stereo speakers, it helps to think of sounds as falling into three basic categories: high-frequency sounds, low-frequency sounds, and mid-range ones. Most people think of low-frequency sounds as bass and high-frequency ones as treble. The woofers and subwoofers of a car stereo’s speaker system handle the bass sounds, while tweeters handle treble.
The sound of car alarms going off in the middle of the night is a now familiar part of the urban landscape. There is a lot more to the car security systems of today, though, than simple noisemakers. Car security systems have become more sophisticated, and many now sport a dizzying array of features.
Groundshaking bass, that’s what subwoofers are all about. It’s not just the volume that creates the thumping vibration so familiar to anyone who lives near a teenager or a hard-core car audio fan, it’s the types of sounds subwoofers are designed to handle. Subwoofers pick up the very low-frequency sounds (100 Hz or less) that ordinary bass speakers can’t handle.
Car LCD screens are rapidly becoming staples of the mobile entertainment centers that modern vehicles have become. These monitors are typically used for watching TV and playing DVDs, videos and games. LCD screens are also becoming more common in other vehicle display applications, such as in GPS navigation devices, radios, car alarms, and so on.
There’s an old stereotype to the effect that male drivers won’t ask for directions when they’re lost. If the cost of car GPS systems continues to drop, they may never have to. Unlike human beings, GPS receivers always know where they are, night or day, in any weather, no matter how remote the location.
The first question to address when looking at car DVD players is whether you’d prefer to purchase the receiver separately from the monitor, or purchase them together as part of a single unit. Receivers sold separately typically include other functions besides playing DVDs. For example, they may play CDs, MP3s, and videocassettes, as well.
Even before Howard Stern left the FM airwaves and embraced the brave new world of satellite radio, the Sirius and XM satellite networks were becoming some of the hottest media outlets of the day. Anyone who takes his or her ability to stay on the cutting edge seriously (or semi-seriously) should check out investing in satellite radio for the car. The beauty of satellite radio is that it allows you to listen to broadcasts from anywhere in the world, not just your local broadcast area.
The aftermarket in car audio systems is huge, and for good reason–car audio systems are surprisingly important to consumers. A number of studies have shown that listening to one’s favorite music reduces stress, which is exactly what today’s gridlocked commuters need the most. People who don’t want to make do with the car audio systems that come with their vehicles turn to aftermarket car audio systems to upgrade their rides.
The basic purpose of the amplifier in a car audio system is to amplify the sound coming from the pre-amplifier before feeding it to the speakers. Since most installed car audio system amplifiers have relatively low power, it is common practice among car audio enthusiasts to install an aftermarket amplifier. Although many people think the main reason for getting a higher power amplifier is simply to make the car’s audio system louder (and it will do that), an amplifier also improves sound quality at all volume levels.
If you want to save money on aftermarket car audio systems, and all the other fun electronic gadgets the modern marketplace has to offer, one way to do so is to search for an electronics wholesaler that will sell direct to consumers. Fortunately for buyers, the Internet has made electronics goods at wholesale prices more accessible to individuals. Recent research has shown that consumers are often more satisfied with their online electronics shopping experience than they are with shopping at traditional offline outlets.
The term wholesale electronics has traditionally referred to electronics goods held in large quantities by distributors for resale to retailers, other wholesalers, or sometimes directly to consumers. The prices for wholesale electronics are typically substantially lower than the prices for retail goods. There are two reasons for this.
The basic purpose of radar detectors is to detect the radar signals police use to catch drivers violating the speed limit. There are a large number of radar detectors on the market, though, many of them advertising new and advanced features, which can make the process of choosing a radar detector difficult. Here’s a brief description of some of the newer features in today’s radar detectors.
You’ve probably heard of the iPod by now, but you don’t have to buy one of these Apple devices to get a top-quality MP3 player. Top brands like Sony have gotten into the market in a big way.
It can be quite difficult when looking at DJ equipment for sale to figure out what to buy, particularly if you are putting together your first setup. Perhaps the first thing to do is decide what your budget is and start with the basics. At the very least, you will need a mixer, turntables, and perhaps a professional CD player, as well as headphones and a mic.
The most important element of a marine audio system is obviously resistance to water damage. You can’t expect to avoid water in a marine environment. Boating presents more potential dangers to your marine audio system than just splashing however, such as the effects of humidity, wind, salt, corrosion, chlorine, sun, and so on.
It’s pretty hard for the average electronics geek to resist the lure of a handheld GPS unit. As the technology becomes more sophisticated, and bells and whistles are added, it may become more difficult for anyone to resist these handy gadgets. It would not be surprising if these they became as ubiquitous as cell phones.
The latest portable DVD players on the market are not only convenient, they’re cool. Advancements in technology have meant that many portable DVD players today use TFT (thin film transistor) LCD screens capable of providing a brighter, clearer, faster picture. Unlike the portable TVs and VCRs of yesteryear, these DVD players can actually be a pleasure to watch.
Anyone venturing into the world of digital camera ownership for the first time can be forgiven for feeling a bit overwhelmed by the choices. Here are some basics of buying digital cameras to get you started.
If you have a digital camera, at some point you’ll probably find yourself needing accessories to help you use it more efficiently. The first accessory you’ll want to purchase is a memory card. Most digital cameras are sold with minimal memory, enough to hold only a few pictures.
