Nakamichi N-T39 Tweeters
The Nakamichi N-T39 is a tweeter designed for demanding listeners who expect maximum clarity, space and fine detail from their audio system. Thanks to the large 30 mm silk dome (ASV Silk Dome) it delivers an exceptionally natural and smooth presentation without aggression even at high volumes. A strong neodymium magnet with high magnetic induction ensures precise control of the diaphragm, high dynamics and fast response, while the large 25.5 mm KSV voice coil contributes to high power handling and long-term reliability. The result is an open, airy sound with excellent instrument and vocal localization, which perfectly complements high-quality component audio systems focused on faithful music reproduction. The package includes two pairs of mounting accessories – housings for surface mounting on the dashboard and adapters for flush installation. The tweeter itself can also be easily removed from the mounting cup, which significantly simplifies installation into original factory positions in the vehicle.

About the brand
The history of the Nakamichi brand goes back to 1948, when it was founded in Japan by Etsuro Nakamichi. His journey began with the establishment of the Nakamichi Research Corporation in Tokyo, focused on research of sonars, magnets and development solutions for leading brands, government institutions and universities. From the beginning the brand was built on a scientific approach, deep understanding of sound and emphasis on technical precision. A pivotal period of growth came in 1972, when Takeshi Nakamichi joined the company and greatly contributed to the development of legendary audio products sold worldwide. Under his leadership, for example, the Nakamichi 1000 was created, the first cassette deck in the world. Thanks to the combination of top sound and timeless design, on which the brand's chief engineer Kozo Kobayashi also worked, Nakamichi products became icons of their time. Nakamichi remains successful today. Its portfolio offers high-quality products for home and car audio that stand out for thoughtful construction, quality workmanship and excellent sound within their price category.

| 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 |
| RMS powerRMS speaker power is the constant power of the entire system, not just one speaker or one side. This is also the performance of continuous use of the speakers. If the RMS power is exceeded for a long time, the speakers may be irreversibly damaged! | 15 W |
| 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. | 6 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. | 1,200 - 20,000 Hz |

| 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 |
