Subwoofer Alpine HDZ-110

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. The massive 28cm HDZ-110 Alpine Status subwoofer features a powerful ferrite magnet to ensure efficient power delivery and boasts an impressive 400W RMS / 1200W Peak Power Handling. The double pickup carbon composite diaphragm minimizes distortion and reproduces clear and precise bass even at high volumes. The HDZ-110 is very similar in look and feel to the AlpineF#1Status subwoofer, using a very similar design and motor assembly, as well as identical construction materials for the highest sound quality.

Main features

High-Resolution Audio Access - The Alpine Status system features many of the technologies, components and materials of the AlpineF#1Status system to achieve ultra-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.
28 cm high-performance subwoofer - based on the findings from the development of the AlpineF#1Status subwoofer, the 28 cm HDZ-110 Alpine Status subwoofer was created. It features a dual 2 Ohm configuration, an ultra-strong fired carbon diaphragm, dual circuitry, large diameter screw terminals and a huge ferrite magnet.
Carbon Fiber Diaphragm - The HDZ-110 Alpine Status subwoofer is equipped with a carbon composite diaphragm with a back cover to achieve a fully uniform timbre with the Alpine Status speakers - the result is excellent harmony. Carbon is very light and stiff, resulting in high dynamics and low distortion.
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.
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.
Dual 2 Ohm Configuration - this subwoofer is equipped with dual 2 Ohm voice coils to drive 2 mono amplifiers. You can also create a 4 ohm configuration by making a serial connection and using the HDA-V90 amplifier channel.
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.

RMS powerThe RMS power of the subwoofer is the constant power of continuous use of the subwoofer. If the power is exceeded for a longer period of time, irreversible damage may occur, or to burn out the voice coil of the subwoofer.	400 W
Max. (maximum performancePeak performance , which the subwoofer can play momentarily (approx. 0.5 s), for example when hitting drums in a song. If the maximum power is exceeded, damage can quickly occur, or to burn out the voice coil of the subwoofer.	1200 W
Sensitivity (SPL 2.83V/1m)Subwoofer sensitivity or efficiency. The sensitivity of the subwoofer is given in decibels (dB) and, in simple terms, means that the higher the value, the lower the demands on the power of the amplifier. This is a de facto rating of how a subwoofer converts watts to sound. Sensitivity ratings are in noise level measured at 1 meter from the subwoofer using 1 W (watt of power) or using 2.83 volts at the source at 1 meter. A higher decibel level means the subwoofer is louder with less power. For every 3 dB increase in sensitivity, the subwoofer requires half the power to reproduce the same volume. For example, if an 88 dB subwoofer needs 300 Watts to produce a certain volume, then a subwoofer with 91 dB sensitivity needs only 150 Watts to reach the same efficiency.	84 dB
ImpedanceImpedance - measurement of electrical resistance. When buying a subwoofer, it is very important that everyone make sure that the impedance matches the amplifier that you are connecting to it. For subwoofers with a double voice coil, we recommend following the information in the advice center! Example: A 2 Ohm subwoofer cannot be connected to an amplifier that is only stable up to 4 Ohms. A 4 Ohm subwoofer can easily be used on an amplifier that is stable up to 2 Ohms. Connecting a 4 Ohm subwoofer to an amplifier that is stable up to 4 Ohms also without problems. The most common subwoofer impedance is 4 Ohm.	2 + 2 Ω
Frequency rangeThe ability of the subwoofer to play a signal from the lowest frequency to the highest, or the ability of a subwoofer to faithfully reproduce sound in a specific frequency band. Subwoofers ideally play from 20 - 150 Hz. 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 indicate this maximum tolerance of sound pressure in decibels in their catalogs for tactical reasons. 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.	25 - 300 Hz
Subwoofer diameterThe diameter of the subwoofer is indicated on the screw holes. The overall outer diameter of the subwoofer is usually 1-2 cm wider, depending on the size category of the subwoofer. For a 30 cm subwoofer, the outer diameter incl. protective rubber 31.8 cm and in the 25 cm subwoofer it is 26.5 cm incl. protective rubbers.	280 mm (8\")
Subwoofer mounting depthThe mounting depth of the subwoofer is measured from the bottom edge of the magnet to the bottom edge of the subwoofer's metal or cast basket.	196 mm
Fs - resonant frequencyFs - is the lower resonant frequency. This parameter is the de facto free air resonant frequency of the subwoofer. Simply put, it is the point at which the weight of the subwoofer's moving parts equals the force of the subwoofer's suspension while it is in motion. If you've ever seen a piece of string start to hum uncontrollably in the wind, you've seen the effect of reaching a resonant frequency. The weight of the moving parts and the stiffness of the suspension (surround and spider) are key elements that affect the resonant frequency. As a general rule, a lower Fs indicates a subwoofer that would be better at reproducing low frequencies than a subwoofer with a higher Fs. However, this is not always the case, as other important parameters of the subwoofer also enter the resulting sound.	30.8 Hz
Vas - equivalent volume of airVas - represents the volume of air that, when compressed per cubic meter, acts with the same force as compliance (CMS), suspension in a certain subwoofer. Vas is one of the most complicated parameters to measure, as changes in air pressure are affected by conditions of relative humidity and temperature. Another way to describe what VAS is: try using a subwoofer and find a baffle that is the right size to return the air with the same stiffness to the same resonance. The size of this box is equal to you. There are, of course, other parameters, but they are not so necessary for the exact calculation of the enclosure. Resonance frequency and Q-parameter values are also important when building enclosures.	48.9213 l
QesElectrical Q-factor of driver is the electrical quality factor (electrical damping). If the subwoofer coil moves in a magnetic field, it generates its own current that counteracts its movement. Qes is a dimensionless parameter and the lower the number, the higher the generated current and the more damped the coil movement, thus reducing the total current flowing through the coil, the deflection and the sensitivity around the fs resonance. It varies in values from 0.08 to 0.6, in the extremes, for ordinary universal converters, even 20. Subwoofers with too low a Qes value, a very damped system, are not suitable for certain types of enclosures.	0.519
QmsMechanical Q-factor of driver is a mechanical factor of quality (mechanical damping). These are mechanical losses affecting (damping) the movement of the subwoofer membrane. Qms is a dimensionless parameter and the higher the number, the smaller the losses, i.e. the deviation and sensitivity in the lower band is also higher, it ranges around 0.4 - 25.	6.048
QtsTotal Q-factor of driver is a total quality factor, it includes both parameters Qes and Qms (electrical Qes and mechanical Qms). It varies in values from approx. 0.08 to 0.6, exceptionally up to 3. The Qts of the subwoofer is calculated in the same way as, for example, a pair of parallel resistors, so the result is decisively influenced by a smaller value that cannot be exceeded, which is usually Qes.	0.478
