Tweeter Speakers
A tweeter is a specialty speaker which is designed to reproduce sound signals of very high frequency. The human ear is capable of receiving and comprehending sound waves (frequencies) in the 20 Hz to 20 kHz range. When we hear audio video sound being played, it is the activity of drivers which are playing the frequencies. Because of the impracticability of any one single driver to play over all frequencies, the total range of audible frequencies is broken down into many groups of frequencies with specialized and dedicated drivers catering to each group of frequency.
Unlike full range speakers which can produce most of the frequencies, mid range speakers which cover the middle range of frequencies and subwoofers which capture the lowest group of frequencies perceivable to the human ear, tweeters speakers are designed to capture the highest range of frequencies within the audible spectrum for human beings. They are very small speakers having the smallest of drivers and consume minimum power handling to emit the sound waves. They are typically made of lighter materials which are capable of carrying short wavelengths faster and with greater fidelity. Softer materials such as cloth, silk or polypropylene will produce refined but mellowed output and hard materials such as ceramics, in contrast will produce bright but snappy sounds. If you’re looking to buy a pair of coaxial speakers, then it is imperative that you check out their frequency response and make sure that they are magnetically shielded.
There are about nine types of tweeter speakers available. Cone tweeters looks similar to typical loudspeakers, but churn out higher frequencies. Usual places to find them would be car speakers for stereos and older versions of audio systems. Dome tweeters are devoid of frames and have a voice coil connected to the dome, which in turn is attached to a magnet via a suspension mechanism. Ribbon tweeters possess thin diaphragms with planar coils made of aluminum vapor enclosed within a magnetic field. Piezo tweeters contain a piezoelectric crystal attached to the diaphragm. Electrostatic tweeters also have a thin diaphragm coated with a conductive material and suspended between two screens known as stators. Planar magnetic tweeters have a heavier diaphragm and have a different set of magnetic structures. These tweeters do not need any direct power (voltage) or any electric discharge. Horn tweeters are used to effectively control dispersion and to derive more synergy between the driver, the diaphragm and the air column around the diaphragm. Then, there are ATM tweeters and Ion tweeters. DIN tweeters are relatively complicated than other tweeters. Car audio/video systems get the most benefit out of these.
While buying tweeters and to avoid causing damages, it is necessary to ensure that it configures well with the other components (speakers and amplifiers). Installation is not difficult provided one exercises the required amount of caution. Its better to choose tweeters with built in crossover circuitry. The audio wires from the audio out slot of the amplifier should be properly connected to the tweeter’s wires in conjunction with other full range or midrange speakers. The Boss Audio BASS600 8-Inch Low-Profile Amplified Subwoofer is available at a 65% discount over at Amazon and is probably one of the best speakers that is out there. If you;d like a wall or a ceiling speaker set then the JBL SP6CSII Round 6.5 Inch Stereo Dual-Tweeter In-Ceiling Speaker makes for a great purchase as well.
