Frequently Asked Questions about Gold 11M/4631G05

What are the dimensions of the Scanspeak Automotive Gold 11M/4631G05 midrange driver?

The Scanspeak Automotive Gold 11M/4631G05 is a 4-inch midrange driver with a diameter of 11 cm. This compact speaker fits perfectly into standardized speaker mounts, especially in vehicles designed for 4-inch speakers. Integration into an existing audio system is seamless, as long as there is enough space for the paper diaphragm and the aluminum die-cast basket. Its compact design ensures it can easily fit in doors or dashboards. The lossless linear suspension also guarantees reliable and stable operation, even under heavy use.

What power and sensitivity does the Scanspeak Automotive Gold 11M/4631G05 midrange driver have?

The power of the Scanspeak Automotive Gold 11M/4631G05 midrange driver is indicated by a sensitivity of 90 dB, which means the speaker sounds effective and clear even at low power. The nominal impedance is 4 Ohm, which enhances performance and compatibility with most amplifiers in the automotive sector. With a resonance frequency (Fs) of 68 Hz and a Bl value of 5.5 Tm, it delivers powerful and detailed sound that meets the high demands of audiophiles. The aluminum die-cast basket minimizes unwanted vibrations.

What frequency characteristics does the Scanspeak Automotive Gold 11M/4631G05 offer?

The Scanspeak Automotive Gold 11M/4631G05 has a frequency resonance of 68 Hz, allowing it to accurately reproduce deep mids. The Thiele-Small parameters, including a Q factor (Qt) of 0.31 and an equivalent volume (VAS) of 2.7 liters, indicate excellent frequency reproduction optimized for high-end audio requirements. The ratio of stiffness to mass allows for precise frequency representation, while an Sd of 50 cm² defines the diaphragm area responsible for a clear and powerful midrange.

How is the magnet system of the 11M/4631G05 constructed?

The magnet system of the Scanspeak Automotive Gold 11M/4631G05 is a top-class neodymium magnet system. Neodymium has the advantage of high power density compared to conventional ferrite magnets, leading to improved sensitivity and control of the diaphragm movement. The neodymium magnet ensures stable and consistent performance output, even with prolonged use. Additionally, the system is protected by a magnetic cover and a grille in front of the pole core drilling, which increases durability and optimizes sound reproduction.

What materials are used in the construction of the 11M/4631G05?

The Scanspeak Automotive Gold 11M/4631G05 midrange driver uses a 4-inch paper diaphragm, which is known for its excellent acoustic performance and linear reproduction. The construction is supported by an aluminum die-cast basket, which enhances structural integrity and improves heat dissipation. Together, these materials ensure a lightweight and accurate movement of the diaphragm. Additional support is provided by the lossless linear suspension, which ensures stability despite mobility and dampens vibrations.

What technical advantages does the aluminum die-cast basket offer in the 11M/4631G05?

The aluminum die-cast basket of the Scanspeak Automotive Gold 11M/4631G05 offers a range of technical advantages. Its rigidity ensures precise and distortion-free sound reproduction, while the material is robust enough to guarantee long-term resistance to mechanical stress. Aluminum also provides excellent thermal conductivity, improving thermal dissipation and minimizing the risk of overheating. The stable base ensures even loading of the diaphragm, leading to improved overall dynamics and clarity.

What makes the lossless linear suspension of the 11M/4631G05 special?

The lossless linear suspension of the Scanspeak Automotive Gold 11M/4631G05 is a technical highlight designed specifically to allow diaphragm movement without delay or loss. This special suspension combines elasticity and stability to prevent any form of unwanted resonances. Especially at high volumes, the linear suspension is responsible for maintaining the integrity of sound reproduction. It ensures consistent performance as well as an extended lifespan of the product compared to conventional suspension systems.

Can the Scanspeak 11M/4631G05 be installed in my vehicle?

Whether the Scanspeak Automotive Gold 11M/4631G05 fits in your vehicle depends on the existing speaker mounts. It is important that your car has mounting locations for 4-inch speakers. The available installation space, especially in the area of doors or dashboards, must also consider the size of the 11 cm midrange driver. Compatibility may be influenced by the depth of the aluminum die-cast basket, so a thorough check and measurement is advisable to ensure a proper installation and enjoy the best sound quality.

How does the resonance frequency of Scanspeak 11M/4631G05 affect the sound image?

The resonance frequency of 68 Hz in the Scanspeak Automotive Gold 11M/4631G05 is a central factor for its sound characteristics. A low Fs value like this allows for clean and clear reproduction of lower frequencies, which is crucial for a midrange driver. The tonal balance is supported by the low Qt value of 0.31, enabling precise bass and midrange performance. With a VAS of 2.7 liters, the speaker shows an ideal response regarding volume adjustments in small enclosures or vehicle cabins to maximize sound precision.

How does the Bl value of the 11M/4631G05 contribute to acoustic performance?

The Bl value of 5.5 Tm in the Scanspeak Automotive Gold 11M/4631G05 indicates the product's coil length and magnetic flux density and reflects the driving force on the voice coil. A higher Bl value means more control over the diaphragm movement, ensuring accurate and distortion-free sound reproduction, especially of midrange frequencies. This leads to clearer tones and an overall improved dynamic range. A precise Bl value ensures that even at maximum volume, the integrity of the audio signal is maintained without causing sound distortions.
