Alpine HDZ-653S speakers

Alpine has created an all-new "Alpine Status" sound system using the same technical and design concepts used in the third generation AlpineF#1Status Ultra High Definition system to achieve high definition sound at a more affordable price. The Alpine Status system is also extremely flexible: all components can be purchased and used in a "stand-alone" configuration. For audiophiles looking to create the ideal sound system, Alpine Status offers a wide range of speakers with Hi-Res Audio support. The HDZ-653S Slim-Fit Tri-Way High Definition 55Hz - 40kHz Speaker Kit includes a 170mm door woofer, a 96mm midrange speaker and a 40mm Slim-Fit tweeter that easily installs into your car's original tweeter locations . Top x-over speakers are also included. All speaker diaphragms are made of the same carbon composite material to create a uniform identity of sound color during playback. Very close in look and feel to the AlpineF#1Status speakers, they use a very similar design and motor setup, as well as identical construction materials for the highest sound quality.

Main features

Hi-Res Audio Accessing High-Resolution Audio - The Alpine Status system features many of the technologies, components and materials of the AlpineF#1Status system to achieve extremely accurate music reproduction - at an affordable price. It is designed to play 192 kHz / 24-bit music tracks that are widely available in many online stores and streaming platforms. High-resolution 192kHz / 24-bit audio playback enables Alpine Status to create an elevated in-vehicle listening experience that mimics the feel of an intimate recording studio session.
Slim-Fit 3-Way Speaker System - Sound-certified speakers provide the highest audio quality for audiophiles up to 40kHz in your vehicle. The 3-way system consists of 170mm door woofers, 96mm midrange speakers and 40mm Slim-Fit tweeters. The set also includes high-end X-over nets.
Carbon Fiber Diaphragm - All speakers in this set (as well as the HDZ-110 Alpine Status subwoofer ) use reinforced carbon composite diaphragms to achieve a fully unified timbre identity - resulting in excellent harmony. Carbon is very light and stiff, resulting in high dynamics and low distortion.
Premium build quality - Trickle-down technology - double edge allows for maximum diaphragm deflection with excellent diaphragm control and stability. This reduces the sound distortion caused by the vibration of the diaphragm at higher volume levels.
Slim-Fit Tweeter - The included 40mm Hi-Res Audio slim-fit tweeters sound simply amazing and play up to 40kHz. They are significantly smaller than the HDZ-653 tweeters with a focus on ease of installation. They also feature an integrated waveguide, a tuned rear chamber and a strong neodymium magnet.
Alpine Status Full System - contains many components that are optimized for power and performance as a complete system for playback in the intended high definition specification for excellent audiophile sound quality. However, each component can be purchased separately to build your own system.
Audiophile speaker X-Overs - the included 3-way x-over networks contain hand-picked, high-end components and offer many adjustment options: you can adjust the mid-range level from 0 dB to -3 dB, the tweeter level from +3 dB, 0 dB or -3dB and you can set the X-Over woofer to 12dB/oct or 6dB/oct. Smoked acrylic cover with Alpine logo can be slid forward to access screw terminals and jumpers.
The audiophile version of the tweeter - 70mm Hi-Res Audio circular tweeters sound simply amazing and play up to 40kHz. They feature a 25mm carbon fiber diaphragm that is tuned to perfectly match the mid-woofer and woofer to achieve a fully uniform color. They also feature an integrated waveguide, a tuned rear chamber and a strong neodymium magnet.
Studio recording specification - Alpine Status achieves 192kHz/24bit playback, which is 6.5 times the amount of digital audio data in a standard CD or digital streaming service and exceeds the standard 96kHz/24bit high definition specification found in most audio aftermarket solution. This allows Alpine Status to capture and accurately reproduce details such as a performer's breath or a musician's subtle interaction with an instrument. This capability not only reproduces the music as originally intended by the artist, but mimics the in-vehicle studio recording experience.

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!	100 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!	300 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.	55 - 40000 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.	170 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.	67 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.	Carbon composite
Center speaker diameterThe diameter of the center speaker is given as the diameter of a round speaker, not including the mount, where the mounts protrude even more on smaller speakers.	96 mm
Mounting depth of the center speakerThe mounting depth of the center speaker is measured from the bottom edge of the magnet to the bottom edge of the tin, plastic or cast speaker basket.	38.9 mm
Overall tweeter diameterThe total diameter of the tweeter is given as the diameter of the individual tweeter without the installation houses.	40 mm
The overall depth of the tweeterThe total depth of the tweeter itself without the installation houses.	12.3 mm
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.	Yes
