Gladen Zeta 10 subwoofer

The Zeta line represents the pinnacle of Gladen's technical approach to car audio, emphasizing maximum accuracy, control and reproduction fidelity. Zeta subwoofers were developed as a natural extension of this concept toward the lowest frequencies. They are not aimed at short-term maximum acoustic pressure, but at deep, accurate and stable bass that integrates smoothly with quality front systems and supports the overall sound without unnecessary dominance. Low distortion, high control and musicality are the fundamental pillars of the entire Zeta subwoofer range.

Long-throw motor with advanced magnetic system

The ZETA 10 subwoofer is designed with emphasis on high power handling, low distortion and long-term operational stability. At its core is a powerful long-throw motor system with a large 145 mm magnet and a 2" voice coil. The motor includes two integrated aluminum shorting rings that stabilize the magnetic field at higher cone excursions and significantly reduce nonlinear distortion at high volumes. This allows the subwoofer to retain precise control and a clean character even under very dynamic loads.

Aluminum cone

The extremely stiff aluminum cone ensures clean piston motion even at large excursions and also contributes to efficient heat dissipation under high continuous loads. A newly developed, optimized outer surround guarantees stable guidance during long excursions and limits mechanical nonlinearities at higher volumes. The reinforced aluminum pressure basket is fully ventilated and complemented by additional ventilation ports in the neck area of the cone, which reduce air compression and minimize audible air turbulence. The result is cleaner, calmer bass performance without distracting artifacts.

2" voice coil

The voice coil is wound on a robust fiberglass former and features a four-layer construction that increases cone control and improves thermal stability during prolonged loads. A linearly designed spider ensures precise cone guidance, stable parameters and long life even under extreme operating conditions. Thanks to the combination of high linear excursion, a stable motor and effective cooling, the Zeta 10 is also suitable for demanding applications where high dynamics are required without compromise in sound quality.

Wiring flexibility and compact installation

The Zeta 10 is equipped with dual 2 Ohm voice coils, offering high flexibility in wiring design and allowing optimal matching to power amplifiers. This makes it easy to combine the subwoofer with powerful amplifiers in various configurations. The driver's optimized parameters allow use in both sealed and ported enclosures, while the subwoofer maintains control even in smaller volumes. This makes it ideal for demanding installations with limited space where the priority is sound quality rather than just bass quantity.

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.	300 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.	600 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.	86.1 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
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.	250 mm (10\")
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.	147 mm
Recommended enclosure volumeThe closed enclosure is characterized by a simple construction. Closed enclosures are usually smaller than bass-reflex enclosures, and a special damping fleece is used for their damping. A closed baffle has the advantage of preventing an acoustic short between the front and back radiation of the subwoofer diaphragm. The disadvantage is that the closed enclosure raises the natural resonance frequency of the used subwoofer and thereby also increases the lower limit frequency. This is because the back side of the diaphragm is forced to compress and dilute the air inside the enclosure when the subwoofer is radiating in a closed enclosure. This adds to the inherent stiffness of the subwoofer's oscillation system the stiffness of the air in the closed enclosure. This causes an increase in the stiffness of the oscillating system and thus an increase in the resonant frequency of the entire system: subwoofer -> loudspeaker. The increase in resonant frequency for a given subwoofer is greater, the smaller the volume of air in the closed enclosure. The relatively small volume of air in the closed enclosure acts on the subwoofer as an acoustic spring when radiating the back side of the membrane into the enclosed enclosure. USE: Mainly for quality bass listening in the entire band with an emphasis on detail and accurate reproduction in the lower band. Pros and cons: + pure reproduction + small closets + easier tuning - low level of efficiency in deep bass - loudness only at the cost of enormous deflection of the membrane - a significant acoustic pressure cannot be expected	17 l
Recommended bass reflex speaker volumeA bass reflex enclosure is designed in the same way as a closed enclosure, but it also has a so-called bass reflex mouthpiece, or "bass reflex" or slot. Needle foam is used to dampen bass reflex enclosures. USE: The ideal use is in cases where the listener wants to achieve a high volume and a good sound pressure level. It is the best compromise between sound quality and performance and is also the most commonly used Pros and cons: + good efficiency in deep bass + a small deflection of the membrane is enough for a large volume - reproduction less accurate than with closed enclosures	35 l
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.	26.5 Hz
Xmax + -Xmax - the maximum deflection of the subwoofer diaphragm in one direction – it is not a sum, or an abbreviation for the maximum linear deflection. The subwoofer output becomes non-linear as the voice coil begins to leave the magnetic gap.	11.5 mm
Subwoofer voice coil diameterThe larger the diameter of the voice coil, the more load capacity the subwoofer has, in layman's terms.	2\" (50 mm)
Subwoofer diaphragm materialThe specific material from which the subwoofer membrane is made.	Aluminum
