Nakamichi NSA-CS1711 speakers

The NSA series of component speakers stand out especially for their advanced and natural sound full of details. The mid-bass speaker made of composite paper ensures an optimal balance between lightness, durability and stability. Paper, which is of course provided with a waterproof layer, is still considered one of the most suitable materials for high sound quality, and the performance of Nakamichi speakers corresponds to this. The rubber membrane suspension ensures durability for many years. The tweeters made of silk enable a detailed and natural sound with a lightness and delicacy of its own. Their level can be adjusted on the crossover for optimal adaptation of the listener's priorities. The robust and safe packaging and rich accessories, including the option to choose two colors of the tweeter grille, will also impress. The indicated sensitivity of 88 dB is not among the highest, however, according to our testing, the real one is higher and the speakers play very well even on the factory car radio. If we add perfect processing to the above, this is without a doubt our tip for speakers priced up to CZK 3,000.

About the Nakamichi brand

The history of the Nakamichi brand dates back to 1948, when it was founded in Japan by Etsuro Nakamichi. The journey to fulfilling his dreams began with the establishment of a small research institute, Nakamichi Research Corporation, in Tokyo, Japan, providing sonar and magnet research and development for major brands, government entities, universities and organizations. Since then, it has established itself as a trusted creator of high-quality products that are the result of intensive scientific work, a passion for sound and a commitment to uncompromising quality and performance. In 1972, Takeshi Nakamichi joined Nakamichi Corporation, who was associated with the company's boom at the time and was deeply involved in all of Nakamichi's legendary audio products sold in Asia, America and Europe, including the first launch of the Nakamichi 1000, the world's first cassette tape recorder. He was regarded as one of the world's best acoustic and sound engineers, who was able to combine high-end sound with the genius audio product design strengths of Mr. Koza Kobayashi, the brand's chief engineer at the time. Amplifiers, players, and even car radios of that time are now among the legends for their unsurpassed quality. However, the Nakamichi brand is still successful today and produces high-quality products not only in the field of home audio, but also in vehicles. The ingeniously thought-out portfolio of the manufacturer is constantly growing, and practically all products stand out for their high-quality sound and incredible processing in the given price category. The legacy of Etsuro Nakamichi lives on and we are glad that it is not only a sound name, but also reflected in the quality of Nakamichi products.

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.

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!	65 W
Max. (maximum performancePeak performance , which the speaker can play for a moment (approx. 0.5 s), for example when hitting drums in a song. If the max power is exceeded, the speakers will usually be damaged!	450 W
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.	88 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.	53 - 19 500 Hz
The diameter of the mid-bass speakerWe state the diameter of the speaker as the diameter of the entire speaker, not including the mounts, when smaller speakers (87, 100, 130 mm) have extra mounts. Some speakers are oval and there the dimension is given in inches, always the shortest side to the longest side. One inch is approx. 2.5 cm.	165 mm
Installation depth of the mid-bass speakerThe installation depth of the speaker is measured from the bottom edge of the magnet to the bottom edge of the tin, plastic or cast speaker basket, or speaker bearing surfaces.	63 mm
Mid-woofer diaphragm materialThe material that was used for the speaker diaphragm. Don't be afraid of the paper, it surprisingly has a very natural and high-quality sound and, thanks to the surface treatment, it can withstand moisture without any problems.	Kompozitní papír
Tweeter dome diameterThe net diameter of the dome (diaphragm) of the tweeter.	20 mm
Tweeter dome materialThe shell material that was used in the manufacture of the tweeter.	Hedvábí
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.	Ano
