SB17CAC35 / Ceramic by SB Acoustics

The SB Acoustics SB17CAC35 6.5" (16.5cm) midwoofer with ceramic membrane is available in a 4 Ohm and 8 Ohm variant. The ultra-light and stiff membrane is driven by a powerful ferrite magnet. The resonance frequency around 30 Hz is well outside the usable range, allowing the driver to perform extremely linearly in the usable range and making it ideal for 2-way applications or as a pure midrange driver. The generously ventilated centering spider optimizes the rear compression behavior to a maximum and provides additional cooling.

Frequently Asked Questions about SB17CAC35 / Ceramic


Welche Unterschiede gibt es zwischen der 4 Ohm und 8 Ohm Variante des SB17CAC35 / Ceramic?

The SB Acoustics SB17CAC35 / Ceramic mid-woofer is available in two impedance variants, namely 4 Ohm and 8 Ohm. In the 4 Ohm version, the DC resistance, Re, is 3.1 Ω, while in the 8 Ohm variant it is 5.7 Ω. The nominal sensitivity in the 4 Ohm version is 90 dB, while the 8 Ohm variant offers a sensitivity of 86.5 dB. Additionally, the mechanical Q factor, Qms, is 4.70 for 4 Ohm and 4.46 for 8 Ohm. The total Q factor, Qts, also differs: 0.29 for 4 Ohm and 0.36 for 8 Ohm. Both variants offer a nominal power handling of 60 W.

Welche Vorteile bietet die Keramikmembran des SB17CAC35 / Ceramic?

The ceramic membrane of the SB17CAC35 / Ceramic speaker is geometrically reinforced to enable optimal piston operation. This construction ensures minimal breakup and thus provides excellent control in the usable range. The ultra-light and rigid membrane is driven by a powerful ferrite magnet, making it not only precise but also extremely efficient. This results in a very linear frequency response, ideal for use in 2-way systems or as a pure midrange driver. Especially when you are looking for precise and differentiated sound reproduction, the ceramic membrane offers remarkable advantages.

Wie beeinflusst der belüftete Polschuh die Leistung des SB17CAC35 / Ceramic?

The ventilated pole shoe of the SB17CAC35 / Ceramic significantly reduces compression in the driver. Ventilation improves heat dissipation and provides a more stable thermal performance, which increases the driver's resilience. The cooling of the voice coil is optimized, minimizing distortion and enhancing the reliability of the system. This not only improves the longevity of the driver but also keeps the sound quality consistent over a wider volume range. The ventilated pole shoe promotes a fine settling behavior and detailed music reproduction, which is particularly advantageous for precise acoustics.

Welche Frequenzbereiche kann der SB17CAC35 / Ceramic abdecken?

The SB17CAC35 / Ceramic covers a frequency range of 120 Hz to 3 kHz, making it an excellent choice for use as a midrange driver in 2-way systems. This bandwidth ensures that it reproduces both deep midrange tones and higher frequencies with clarity and precision. In the frequency range, the driver is extremely linear, which is underscored by the resonance frequency of about 30 Hz outside the usable range. This means that the driver does not produce unnecessary emphasis or distortion in any frequency range, ideal for high-quality audio playback.

Was sind die Abmessungen und der lineare Spulenhub des SB17CAC35 / Ceramic?

The SB17CAC35 / ceramic speaker has a voice coil diameter of 35.5 mm and an effective diaphragm area of 118 cm². The height of the voice coil is 16 mm, while the air gap offers a height of 5 mm. Additionally, the driver features a linear coil excursion of 11 mm (peak-to-peak), allowing it to perform larger movements without distortion. These dimensions and values represent the high precision and the ability of the driver to accurately reproduce complex sound structures, making it ideal for demanding applications in speaker systems.

Wie beeinflusst der nichtleitende Glasfaser-Schwingspulenträger die Leistung des SB17CAC35 / Ceramic?

The non-conductive fiberglass voice coil carrier in the SB17CAC35 / Ceramic minimizes the damping effects of the speaker. Its design ensures that electrical losses are reduced, leading to improved efficiency and lower inductance. A lower electrical Q factor of Qes 0.31 (4 Ohm) and 0.40 (8 Ohm) supports these characteristics, as it reduces distortion and improves frequency response linearity. This also reduces mechanical losses during operation, allowing for overall clean and precise sound reproduction.

Mit welchen Automarken oder Modellen ist der SB17CAC35 / Ceramic kompatibel?

Although the SB17CAC35 / Ceramic can be integrated into a variety of car models due to its design and dimensions, no specific car brands are mentioned in the product description. Therefore, the focus is on the universal installation dimensions and technical specifications to ensure compatibility. When making adjustments or custom installations, attention must be paid to the measurement of 16.5 cm to ensure that the speaker can be properly mounted. The universal design of the chassis offers flexible installation options, ideal for car enthusiasts and professional installations.

Kann der SB17CAC35 / Ceramic als reiner Mitteltöner genutzt werden?

Yes, the SB17CAC35 / Ceramic is ideally suited as a pure midrange driver due to its technical specifications and geometrically reinforced ceramic membrane. With a frequency range of 120 Hz to 3 kHz, it is perfectly optimized for the reproduction of mids in a speaker system. Its ultra-light membrane and strong magnetic flux density of 1.0 T ensure detailed and clear reproduction of mid frequencies. The combination of low moving mass and ventilation provides optimal conditions for detailed music presentation, especially for demanding HiFi applications.

Wie wirkt sich die CCAW-Schwingspule auf den Klang des SB17CAC35 / Ceramic aus?

The CCAW voice coil (Copper-Clad Aluminium Wire) of the SB17CAC35 / Ceramic results in a reduced moving mass, contributing to efficient sound reproduction. This property promotes a quick response to audio signals, which is particularly advantageous when reproducing complex musical material. Thanks to the lower density and high conductivity, less energy is converted into heat, maximizing acoustic performance. Especially at high volumes, the speaker maintains its clear sound characteristic, which is essential for music lovers who enjoy listening to detailed music.

Welche Rolle spielt das Aluminiumguss-Chassis beim SB17CAC35 / Ceramic?

The aluminum die-cast chassis of the SB17CAC35 / Ceramic is crucial for the structural integrity and acoustic performance of the speaker. This design offers high strength while maintaining low compression of the chassis. The ventilation of the chassis provides improved control over the acoustic properties of the driver. Additionally, it helps to minimize rear reflections and standing waves that could distort the sound image. This precise construction increases the longevity of the components and optimizes overall stability under load, ensuring reliable performance.
