SB17CRC35 / Carbon by SB Acoustics

The SB Acoustics SB17CRC35 6.5 inch midwoofer with glossy Carbon Rohacell® diaphragm is available in 4 Ohm and 8 Ohm versions. The ultra-light and stiff diaphragm is driven by a powerful ferrite magnet. The resonance frequency around 30 Hz lies far outside the usable range, which makes the driver extremely linear in the usable range and ideal for 2-way use or as a pure midrange driver. The generously ventilated centering spider optimizes the rear compression behavior to a maximum and provides additional cooling.

Frequent questions about SB17CRC35 / Carbon

Welche Vorteile bietet die Carbon Rohacell® Membran des SB17CRC35?

The Carbon Rohacell® membrane of the SB17CRC35 offers an optimized ratio of stiffness and damping. This combination ensures excellent sound quality through reduced membrane distortion, which is particularly advantageous when used as a mid-bass driver. The ultra-lightweight construction allows for faster membrane movement, improving the transient response. Especially at high volumes, the sound remains clean, as the membrane operates stably and precisely. These characteristics make the driver ideal for use in 2-way systems or as a pure midrange driver. Additionally, the glossy surface enhances the aesthetic appearance, suitable for high-quality HiFi applications.

Wie wirkt sich die verlängerte Kupferhülse am Polschuh auf die Klangqualität aus?

The extended copper sleeve on the pole shoe of the SB17CRC35 reduces the inductance of the voice coil, resulting in lower distortion and a clearer sound image. By improving the magnetic field linearity, it ensures stable conditions for the voice coil, especially at high volumes and complex musical passages. The efficiency of the driver is also increased by these construction elements, as mechanical losses are minimized. This improves the settling behavior and ensures an optimal frequency response. This design significantly contributes to the precise and distortion-free reproduction of even demanding musical pieces.

Welche Unterschiede gibt es zwischen der 4 Ohm und der 8 Ohm Variante des SB17CRC35?

The SB17CRC35 is available in a 4 Ohm and an 8 Ohm variant, with differences in electrical properties and sensitivity. The 4 Ohm variant has a higher sensitivity of 90 dB compared to 87 dB for the 8 Ohm version. This means it sounds louder at the same voltage. The inductance of the voice coil is lower in the 4 Ohm version at 0.13 mH compared to 0.15 mH in the 8 Ohm, allowing for a slight advantage in transient response. The electrical damping also differs, affecting adaptability to different types of amplifiers. Both variants offer excellent sound quality, but the choice depends on the specific requirements of the system.

Wie montiere ich den SB17CRC35 in meinem Lautsprechergehäuse?

The assembly of the SB17CRC35 is technically demanding, as the dimensions must be considered precisely. The back should be adequately ventilated, as the ventilated aluminum die-cast chassis requires space for rear sound radiation. Therefore, the chassis opening must fit precisely to the 6.5" (16.5 cm) driver to ensure a secure fit without cabinet resonances. It should also be ensured that the installation depth does not interfere with the chassis. A symmetrical and damped installation increases sound fidelity and ensures a harmonious interaction in the frequency range of 70Hz to 4kHz. Additional rubber dampers can help minimize mechanical vibrations.

Welche Thiele Small Parameter sind für den SB17CRC35 wichtig?

The Thiele Small parameters of the SB17CRC35 are essential for tuning in loudspeaker systems. The effective diaphragm area Sd is 118 cm², which affects bass dispersion. The mechanical Q factor Qms of 4.32/3.90 for 4/8 Ohm indicates the mechanical losses, while the electrical Q factor Qes at 0.35/0.37 describes the electrical damping. The total Q factor Qts shows with 0.32/0.34 how the driver influences bass reproduction in a closed or open enclosure. The free air resonance Fs is at 31.5/28 Hz and affects bass depth. These parameters help to optimally integrate the driver into a loudspeaker system, whether in a bass reflex or closed enclosure.

Warum ist der Polschuh des SB17CRC35 belüftet?

The ventilated pole shoe of the SB17CRC35 has a specific goal: to minimize compression effects and thus improve fidelity at high volumes. The ventilation promotes effective heat dissipation, allowing the driver to achieve a higher thermal load capacity. Heat generation can significantly affect sound quality, so the ventilation structure helps to regulate this. Additionally, the diaphragm travel is optimized, as the airflow behind the diaphragm remains unaltered. This design decision enhances performance efficiency and minimizes distortions that would otherwise be amplified at high power levels.

Welche Bedeutung hat der CCAW-Schwingspulenträger im SB17CRC35?

The CCAW voice coil carrier of the SB17CRC35, a combination of copper and aluminum, effectively reduces the moving mass of the diaphragm, allowing for faster settling and better impulse response. The lighter structure of the voice coil increases the sensitivity of the driver, especially in the critical midrange, improving the reproduction of details. Additionally, the CCAW carrier offers high thermal stability, ensuring reliability under continuous loads or high volumes. These characteristics contribute to the SB17CRC35's ability to play complex musical pieces accurately and without audible distortion.

Wie beeinflusst die mechanische Belastbarkeit die Leistung des SB17CRC35?

With a rated power of 60 W according to IEC 268-5, the SB17CRC35 achieves high mechanical load capacity, which is important for long-lasting sound quality. This load capacity ensures that the driver maintains its tonality even at high sound pressures, minimizing the risk of distortion. The mechanical loss of 0.65/0.6 kg/s ensures that the loss energy is efficiently dissipated, thereby improving the overall performance of the speaker system. When used in a 2-way speaker arrangement, this load capacity helps to ensure a full and resonance-free sound image, even with highly varying musical pieces.

Welche Abmessungen hat der SB17CRC35 Tiefmitteltöner?

The SB17CRC35 is a 6.5 inch (16.5 cm) midrange driver and requires suitable installation dimensions in speaker enclosures. The effective diaphragm area is 118 cm², which allows for ideal integration into medium to large speaker enclosure systems. Especially during installation, attention must be paid to rear ventilation, as a well-ventilated chassis increases mechanical efficiency. The voice coil height of 16 mm and the linear coil excursion of 11 mm provide enough headroom for defined bass reproduction, while the magnetic flux density of 1.0 T ensures constant force transmission. The exact arrangement also plays a role in fully exploiting the driver's potential.

Welche Automarken sind mit dem SB17CRC35 kompatibel?

The SB17CRC35 is primarily designed for HiFi applications and is less tailored for specific car brands. However, the 6.5-inch driver with its 16.5 cm diameter can be used in various vehicle models that offer space for speakers of this size. It is particularly suitable for larger vehicles or models with specified 6.5-inch speaker cutouts. However, the installation requires appropriate mounting tools and enclosure modifications to fully exploit the potential of the technical specifications. A prior check in the vehicle manual can be crucial to avoid complications and ensure seamless integration.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
