This construction ensures efficient heat dissipation and prevents overheating, ensuring the long-term reliability of the midrange driver. The robust chassis contributes to the stability of the cone and ensures consistent sound quality even under demanding conditions. Perfectly suited for installation in all vehicle types, supported by on-site installation in Frankfurt (Oder) .
Low DC resistance and low inductance for efficient power use
The SB17CRC35 woofer impresses with a low DC resistance (Re) of 3.1 Ω (4 Ω version) and 5.7 Ω (8 Ω version), enabling efficient power utilization and reducing amplifier load. The low voice coil inductance (Le) is 0.13 mH for the 4 ohm version and 0.15 mH for the 8 ohm version, supporting fast response times and precise sound reproduction. These technical characteristics are crucial for integration into high-performance car hi-fi systems, as they ensure optimal performance and low distortion.
Extended voice coil with CCAW principle for reduced moving mass
The SB17CRC35 features a CCAW voice coil, which ensures reduced moving mass and thus enables faster and more precise response to audio signals. The extended copper sleeve on the pole piece contributes to low inductance and minimizes distortion, promoting particularly clear and detailed sound reproduction. This advanced voice coil technology improves the efficiency of the midrange driver and ensures outstanding sound quality in your vehicle.
Excellent free air resonance and Q-factors for precise sound characteristics
With a free air resonance (Fs) of 31.5 Hz (4 Ω) and 28 Hz (8 Ω), the SB17CRC35 is well below the useful range, enabling extremely linear reproduction in the audible range. The mechanical Q-factors (Qms) of 4.32 (4 Ω) and 3.90 (8 Ω) and the electrical Q-factors (Qes) of 0.35 (4 Ω) and 0.37 (8 Ω) contribute to precise control of the oscillations. The overall Q-factor (Qts) of 0.32 (4 Ω) and 0.34 (8 Ω) optimizes the transitions between the frequency ranges and ensures seamless integration into two-way systems or as a dedicated midrange driver.
Highly sensitive rubber surround and non-conductive fiberglass voice coil former
The SB17CRC35's rubber surround is designed with low damping for improved transient response and natural sound reproduction. The non-conductive fiberglass voice coil former minimizes vibration damping and ensures the diaphragm responds precisely to audio signals. These technical features contribute to the high sensitivity of 90 dB (4 Ω) and 87 dB (8 Ω), ensuring clear and loud reproduction without compromising sound quality.
Optimal cooling thanks to generously ventilated centering spider
The SB17CRC35 features a generously ventilated spider that maximizes rear compression and allows for additional cooling. This design prevents overheating during extended playback times and ensures consistent performance under all conditions. The improved cooling contributes to the longevity of the midrange driver and ensures reliable operation even under intensive use. This is especially important for use in high-performance car hi-fi systems where stable temperature control is crucial.
Net weight and magnet weight for optimal handling and performance
With a net weight of 1.56 kg and a magnet weight of 0.54 kg, the SB17CRC35 offers a fine balance between stability and efficiency. The heavy magnet weight ensures a strong magnetic flux density of 1.0 T, which enhances the performance and precision of the midrange driver. The overall weight contributes to structural integrity and prevents unwanted vibrations that could impair sound quality. These characteristics make the SB17CRC35 ideal for long-term use in various vehicle types.
Powerful rated power of 60 W for intensive sound reproduction
The SB Acoustics SB17CRC35 woofer/midrange driver has a rated power handling of 60 W according to IEC 268-5, measured with the drivers retracted. This high power handling enables robust and intense sound reproduction, even at high volumes. The rated power handling is crucial for integration into high-performance car hi-fi systems, as it ensures stable and reliable performance without overheating or distortion. This makes the midrange driver ideal for demanding audio setups requiring high power consumption.
