Discover the Sigma 165-X from Gladen, a 6.5" (16.5cm) Coaxial Speaker that features a coaxial coincidence arrangement. The 19mm Tweeter is positioned at the center of the mid-bass driver, ensuring a stable phase alignment and a homogeneous radiation pattern. This design is specifically intended for installation in cars and provides a precise sound image, even in compact installation spaces. The Sigma 165-X impresses with a resonance frequency of 48.9 Hz and a Qts of 0.41, allowing for controlled and balanced playback. The 165mm woofer with its HEXATEC compound membrane offers extended maximum excursion and dynamic musical drive. Immerse yourself in an exclusive sound experience that enriches your car audio system.

The SW165 coaxial speaker is designed as a point sound source (Single-Point) for vehicle installation. The coaxial arrangement of the 19mm tweeter in the acoustic center of the mid-bass driver ensures stable phase alignment and a homogeneous radiation pattern across the entire frequency range.

With a resonance frequency of 48.9 Hz and a Qts of 0.41, the driver is designed for controlled playback in door volumes and compact installation spaces. This tuning allows for precise bass and kick bass representation without overemphasis and supports clean fundamental tone reproduction.

Maximum flexibility combined with unique performance: The GLADEN SIGMA series perfectly combines these two worlds. A 165mm woofer with a novel HEXATEC compound membrane and extended maximum excursion impresses with musical drive.
"The GLADEN SIGMA series stands for exclusive car audio speakers that make every car audio system an unparalleled sound experience."

Frequently Asked Questions about Sigma 165-X

What specific features make the Sigma 165-X unique in the car installation field?

The Sigma 165-X from Gladen is a coaxial coincidence speaker, whose uniqueness lies in the coaxial arrangement of the 19-mm tweeter in the acoustic center of the 165-mm mid-bass driver. This construction ensures a stable phase position and homogeneous radiation behavior, which is particularly crucial for installation in vehicles. The speaker has been specifically designed for compact installation spaces, providing dynamic musical drive through its extended maximum excursion of the HEXATEC compound membrane. With a resonance frequency of 48.9 Hz and a Qts of 0.41, it is perfectly tuned for reproduction in door volumes, allowing for precise bass and kick-bass representation.

How does the coaxial arrangement of the Sigma 165-X affect the sound experience in the car?

The coaxial arrangement in the Sigma 165-X significantly contributes to the clarity and precision of the sound by integrating the 19-mm tweeter directly in the acoustic center of the mid-bass driver. This ensures coherent and homogeneous radiation behavior across the entire frequency range, allowing the sound to be perceived as a unified sound image. It eliminates phase-related disturbances and enables a stable phase position, which balances the sound ideally. The clear frequency response enhances the representation of both highs and lows, which is particularly beneficial in the acoustically challenging environments of vehicles.

What does the resonance frequency of 48.9 Hz in the Gladen Sigma 165-X convey about its bass capabilities?

The resonance frequency of 48.9 Hz in the Gladen Sigma 165-X indicates that the speaker is particularly well-suited to reproduce low tones accurately. This frequency is crucial for the representation of bass and kick-bass elements, which often hold high emotional and energetic value in music. Combined with a Qts of 0.41, the Sigma 165-X is tuned to deliver clean and controlled bass even in compact installation spaces and door volumes, without overshooting or appearing undefined.

What is the construction and material of the Sigma 165-X speaker?

The Sigma 165-X from Gladen features a thoughtful choice of materials to ensure excellent sound quality. The diaphragm is made of a paper composite, which provides a warm and natural sound. Centering made of Nomex and a surround made of SBR rubber ensure stability and flexibility. The fiberglass voice coil former and aluminum basket offer a robust construction, while the dust cap made of polyurethane provides additional protection and clear highs. The ferrite magnet system allows for powerful drive, while the tweeter is equipped with a silk dome and neodymium magnet system.

What role does the voice coil diameter play in the Sigma 165-X and why is it important?

In the Sigma 165-X, the voice coil diameter is crucial for the performance and sound clarity of the speaker. The 38 mm diameter of the voice coil in the woofer allows for more efficient energy conversion and improves thermal load capacity, leading to higher power and durability, while the 19 mm diameter in the tweeter enables precise reproduction of high frequencies. The size and materials like fiberglass, from which the voice coil formers are made, significantly contribute to the overall sound characteristics and robustness.

How does the magnet system of the Sigma 165-X affect speaker performance?

The magnet system is a key component that significantly influences the overall performance of a speaker like the Sigma 165-X. The woofer uses a ferrite magnet system, which ensures high efficiency and excellent control of the bass range. This means it can reproduce deep bass powerfully and without distortion, which is crucial for an intense listening experience. The tweeter, equipped with a neodymium magnet system, provides a powerful magnetic field despite its compact size, allowing for precise and clear reproduction of high frequencies.

How do Qts and resonance frequency relate to the sound tuning of the Sigma 165-X?

A Qts of 0.41 combined with a resonance frequency of 48.9 Hz shows that the Sigma 165-X from Gladen is specifically designed for narrow enclosure tuning. Such a Qts value stands for controlled, accurate bass reproduction that does not allow for an overemphasis on bass tones. In combination with the resonance frequency, this allows the speaker to provide precise bass imaging and kick bass representation even in restricted installation spaces. The tuning optimizes the sound balance by keeping the frequency response linear and minimizing distortion.

What defines the musical drive of the Gladen Sigma 165-X?

The musical drive of the Gladen Sigma 165-X is due to the innovative HEXATEC compound membrane, which allows for an extended maximum excursion. This choice of material and design enables the speaker to deliver dynamic and powerful sound with effortless authority. Additionally, the combination of the coaxial design with the natural sound character of the paper composite membrane provides an emotional and captivating sound, even under high load. These features support the speaker's ability to present music with greater authenticity and energy.

What should be considered when installing the Gladen Sigma 165-X in the car?

When installing the Gladen Sigma 165-X, it is important to correctly consider the dimensions, especially the 165 mm diameter of the mid-bass driver and the extensive installation depth. The precise fitting in the door volume or other intended installation spaces ensures sound performance and prevents unwanted resonances. The elastic SBR rubber of the speaker can help minimize vibrations, while the sturdy aluminum baskets provide support in varying temperature conditions in the vehicle. Sufficient space around the speaker also guarantees optimal bass reproduction.

How does the material of the tweeter dome in the Sigma 165-X ensure fine high-frequency reproduction?

The silk dome of the tweeter in the Sigma 165-X allows for particularly fine and natural high-frequency reproduction. Silk as a material has the property of naturally damping resonances, leading to a warm and detailed sound. Furthermore, the neodymium magnet system, despite its small size, provides a strong magnetic field that effectively drives the dome. This combination ensures clear, bright, and yet smooth highs without harshness, contributing to harmony and fidelity in the upper frequency range. Thus, the speaker seamlessly integrates into demanding audio installations.
