The most sophisticated, high-tech surround sound system is nothing without quality speakers, and this article will define a few key terms and help you understand everything you need to know about your options, including wall speakers, ceiling speakers , home theater speakers and surround sound speakers.
So what is a speaker exactly?
A speaker is basically a translation machine; translates the electrical signal from a disc, CD or DVD into physical vibrations to create sound waves. A speaker consists of drivers, a diaphragm (also called a dome or cone), a spider, a voice coil, a surround sound or suspension, a basket, and a spider. The speakers also contain a crossover, which is what separates the sound at various frequencies, such as high, low, and sometimes midrange. There are three different types of basic speaker drivers: woofers, tweeters, and midrange drivers.
As mentioned earlier, all speakers contain a voice coil, but you will find that some speakers have dual voice coils. The main advantage that the dual voice coil speaker offers over a single coil is the flexibility of wiring, and they tend to be slightly more expensive, ลำโพงแบรนด์ดัง.
Some other terms you're likely to come across in your speaker hunt, whether you're looking at ceiling, wall, home theater, or surround sound speakers, are two-way versus three-way or even four-way, dual speakers. tweeters, impedance, resistance, sensitivity, power handling and frequency response.
Two-way speakers generally include a tweeter and a woofer, and they often work well when combined with a subwoofer to handle the lower frequencies. Three-way speakers generally contain a tweeter, midrange, and woofer. The four-way speakers contain a tweeter, midrange, a woofer, and a dedicated subwoofer. The style that works best for you really depends on your budget, space, and overall system.
Whether you're considering wall, ceiling, home theater, or surround sound speakers, some other factors you'll want to consider are frequency response, power handling, and sensitivity. Frequency response refers to the Hertz range (or Hz, which is a unit of frequency) that a speaker can reproduce. For example, a 50-20,000 Hz speaker has a greater range than a 65-20,000 Hz speaker.
Power management refers to watts and helps you determine which type of receiver would be best for your speakers, and vice versa. Sensitivity, also commonly known as efficiency, refers to how effectively the speaker uses the power it receives from the receiver. Higher sensitivity means that the speaker will produce more volume without taxing your receiver.
