Gladen Aerospace 60AMT tweeters

Gladen's top-of-the-line Aerospace line embodies the philosophy behind realizing the ultimate in car audio. And that without compromises and limiting the costs of development and production. The high quality reproduction of Aerospace series components has been achieved through a number of technical innovations. These include a seven-layer diaphragm of bass and center speakers, an extremely strong neodymium magnet system or a computer-optimized cast aluminum basket. However, the sound quality of the silk tweeters, which stand out not only for their fantastic vocal reproduction and spaciousness, but also for their incredible high-frequency dynamics and linear frequency response in their entire range, are also worth mentioning. All components are hand-made and assembled in Germany, which guarantees top-quality workmanship with typical German precision. The result is a sound experience that surpasses even the wildest imagination.

About AMT technology

The Aerospace 60 AMT tweeter has a clear, dynamic - energetic sound image, very good impulse response and low distortion. The Air Motion Transformer (AMT) represents a speaker concept that does not require a classic voice coil. A specially designed conductive track made of thin aluminum (also only 12 - 25 µm thick), which has a meandering course, is developed on a thin kapton film (thickness 12 - 25 µm) using complex etching processes. To achieve high production accuracy, the film is folded manually using special tools. Unlike conventional tweeter domes, the AMT compound diaphragm in the speaker does not move front or back to produce tones. The movement takes place in folds, i.e. laterally, similar to the bellows. This causes the cornering air to accelerate and leave the front.
One of the advantages of this technology is that the area of the membrane is larger than the visible area and thus takes up less space. In conjunction with the low weight of the membrane, the result is a detailed and dynamic reproduction. All parts of the cover are painstakingly CNC-machined, nickel-plated, powder-coated and then laser-engraved. The aluminum frame can be dismantled, which allows for an even more compact installation. A special copper cable with a silicone jacket and braid protection is directly connected to the membrane to prevent unnecessary transitions or materials in the signal path.

Speaker typeCoaxial speakers: Coaxial speakers are characterized by a so-called all-in-one design. The tweeter and mid-bass speaker are in one basket. The advantage is simpler assembly, but thanks to the connection or proximity of the bands in one speaker, the sound quality will usually be reduced. As a rule, in the middle of the mid-bass speaker, there is a tweeter whose voice coil works in the second air gap of the common magnetic circuit. The three-way coaxial speaker consists of a mid-bass speaker, a center speaker and a separate tweeter in the front on a special beam. Component Speakers: Component speakers are characterized by a division into individual frequency bands, treble + mid-bass + or. bass band. The individual speakers can be placed completely separately, which results in a better sound and acoustic performance. In the vast majority of cases of component speakers, an external crossover is also supplied, which divides the treble, middle / mid-bass, and into the three-band the bass band or allows setting the decibel level of the tweeter (e.g. +2 dB, 0 dB, -2 dB), steepness (e.g. 6dB/Oct. 12dB/Oct.) or active or bi-amp connection.	High rise
Sensitivity (SPL 2.83V/1m)Sensitivity, sensitivity or efficiency of the speaker. Speaker sensitivity is given in decibels (dB) and simply put, the higher the value, the lower the demands on the amplifier's power. This is a defacto rating of how a speaker converts watts to sound. Sensitivity ratings are in noise level measured at 1 meter from the speaker using 1 W (watt of power) or using 2.83 volts at the source at 1 meter. A higher decibel level means the speaker is louder with less power. For every 3 dB increase in sensitivity, the speaker requires half the power to reproduce the same volume. For example, if an 88 dB speaker needs 100 Watts to produce a certain volume, then a speaker with a sensitivity of 91 dB needs only 50 Watts to reach the same volume.	93 dB
ImpedanceImpedance - measurement of electrical resistance. When buying speakers, it is important to make sure that the impedance matches the amplifier or car stereo you are using. Example: A 2 Ohm speaker cannot be connected to an amplifier that is only stable up to 4 Ohms! A 4 Ohm speaker can easily be used with an amplifier that is stable up to 2 Ohms. The most common speaker impedance today is 3 - 4 Ohm.	4 Ω
Frequency rangeThe ability of the speakers to play a signal from the lowest frequency to the highest, or the speaker's ability to faithfully reproduce sound in a specific frequency band. Professionally: In the frequency range from 40 to 16,000 Hz, the vast majority of fundamental and overtones (harmonics) of all musical instruments are found. We are interested in the course of the radiated sound pressure in this range of frequencies when the loudspeaker system is supplied with constant power. We call this course the frequency characteristic, which tells us the level of radiated sound pressure in decibels (dB) depending on the frequency. The frequency characteristic of a speaker or speaker system can be expressed most succinctly with a graph. Mostly, however, the frequency characteristic is indicated by indicating the maximum tolerance of the sound pressure in the given frequency range, e.g. 50 to 15,000 Hz -+ 6 dB. Since the frequency characteristics of loudspeakers and systems in general are quite uneven, some manufacturers do not even specify this maximum tolerance of sound pressure in decibels in their catalogs for reasons of prestige. Data impoverished in this way is unfortunately worthless. What is valid is that the manufacturer offers a speaker system with a frequency range of 30 to 20,000 Hz, if he is worried about stating the maximum unevenness of the sound pressure in this range, because he can have a tolerance of, for example, +- 20 dB. The unevenness or undulation of the frequency curve in good speaker systems for high-quality music performance should not exceed +-3 dB in the 80 to 12,000 Hz band and +-6 dB in the 40 to 16,000 Hz band. Greater unevenness already depletes or emphasizes certain tonal areas, which can cause audible or even disturbing distortion. The proportion between fundamental tones and higher harmonics also changes, thereby changing the color of the sound, and individual musical instruments as well as the entire musical image sound unnatural.	2.5 - 32 kHz

Frequency crossover included in the packageThe crossover is an important part of defacto all loudspeakers. A crossover usually contains different resistor values, coil sizes, and capacitor types that fundamentally modify the sound. We describe below what the turnouts are for. Component Speakers: A crossover is part of every quality component speaker system. Its task is to ensure the distribution of frequencies that the amplifier produces in the entire acoustic spectrum of frequencies so that each of the speakers receives only that part of the band that it can optimally play in terms of efficiency and minimal distortion. Coaxial speakers: In most cases, coaxial loudspeakers have a simple crossover (6dB/Oct.) formed by a capacitor at the tweeter.	No
