Many soft dome tweeter diaphragms are thermoformed from polyester film, or silk or polyester fabric that has been impregnated with a polymer resin. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In two-way systems there is no mid-range driver, so the task of reproducing the mid-range sounds falls upon the woofer and tweeter. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The paper cone tweeter looks very different from the silk or metal dome tweeters seen in many modern loudspeakers. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Such tweeters are called a plasma tweeter or ion tweeter. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As tweeter technology has advanced, different design applications have become popular. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. He received for his invention of the direct-radiator dome tweeter. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. At the very least, such a loudspeaker may be 2-way employing a woofer (or mid-range/mid-woofer) and a tweeter. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Each of these situations might pass more energy to a tweeter than it can survive without damage. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Other signature characteristic for the products of the company is the widely utilized plasma tweeter technology. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As can be seen the tweeter is much thinner and its acoustic centre is ahead of the woofer's acoustic centre. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The plasma driver only reproduced the higher frequencies as a tweeter; the lower frequencies used a conventional woofer driver. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. He is also known as an active tweeter. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The extra high frequency weighting of the signal could make tweeter damage more likely than if the signal was not clipped. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In the mid 1980s the designs were again updated and redesigned with a new titanium-deposition tweeter diaphragm. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In some tweeter designs, the dome is in fact the only sound radiating surface and so it performs both roles. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Usually the tweeter is much smaller and thinner than a woofer. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In those days, the belief was that only a rigid tweeter was capable of producing high frequencies. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A major problem in tweeter design is achieving wide angular sound coverage (off-axis response), since high frequency sound tends to leave the speaker in narrow beams. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. They are used as part of an audio crossover to direct high frequencies to a tweeter while attenuating bass signals which could interfere with, or damage, the speaker. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Without time-alignment correction, the sound from the tweeter may arrive slightly before the sound from the woofer; this misalignment is not generally addressed in automobile sound systems. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A single amplifier can usually power a woofer and a tweeter only through a crossover filter, which protects each driver from signals outside its frequency range. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The drivers are less fragile than ribbons and considerably more efficient (and able to produce higher absolute output levels) than ribbon, electrostatic, or planar magnetic tweeter designs. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. One major key design difference is multi-axial mounting of different types of loudspeakers in the same footprint, such as a tweeter directly mounted over a woofer. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A common way to do this is so that the front-panel has a step (as shown in the above image) where the tweeter mounts at some distance behind the woofer. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The tweeter has a similar level adjustment. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. There would also be an audio tweeter inside the reader. Hard dome tweeters are usually made of aluminium, aluminium-magnesium alloys, or titanium. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Less commonly, microphones themselves can be used as speakers, almost always as tweeters. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Covering the tweeters with tissue paper was said to produce treble-deficient mixes when replayed on normal domestic hi-fi. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Super tweeters are sometimes found in high fidelity speaker systems and sometimes even in home theater systems. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Most ribbon tweeters emit sound in a dipole pattern. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Modern mid-range speakers and high-range tweeters were placed throughout the room. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The drivers that produce the sound are referred to as tweeters, midranges, and woofers. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. There are therefore special considerations involved in the acoustic join between the mid-range and both the low frequency (woofers) and the high frequency drivers (tweeters). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Dome tweeters are categorized by their voice coil diameter, and range from 19 mm (0.75 in), through 38 mm (1.5 in). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. However, the sweet spot created by the narrow dispersion of cone tweeters is narrow. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In terms of transient capabilities and phase stiffness, the obtained sound quality can not be realised by using conventional tweeters. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Such first-order filter designs typically do not provide adequate low-frequency attenuation for mid-range and tweeters. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Cone tweeters have a narrower dispersion characteristic that is the same as a cone woofer's. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Modern tweeters are typically different from older tweeters, which were usually small versions of woofers.
