Frequently Asked Questions about Heritage Sub


What are the dimensions of the Heritage Sub?

The Heritage Sub from Quartorigo has a diameter of 10 inches, which is 250 mm. This dimension allows for compact integration into various vehicle designs while still providing enough surface area to generate deep bass frequencies. Combined with the paper diaphragm, known for efficient sound reproduction, the overall size remains manageable without compromising sound quality. Due to its ferrite magnet structure and the large 75 mm voice coil, it can deliver impressive acoustic performance despite its relatively standard size.

What role does the 75 mm voice coil play in the Heritage Sub?

The 75 mm voice coil of the Heritage Sub plays a crucial role in the stability and performance of the system. A larger voice coil allows for higher thermal capacity, as it can dissipate heat more efficiently. This is particularly beneficial at the RMS power of 200 watts, as the Subwoofer is able to maintain high output levels continuously without loss of power or overheating. Additionally, the large voice coil supports the movement of the diaphragm, leading to more precise and powerful reproduction of deep bass.

What diaphragm material is used in the Heritage Sub?

The Heritage Sub uses paper as the diaphragm material. Paper is valued for its light weight and good damping properties, resulting in natural and detailed sound reproduction. It allows for more precise control of movement at low frequencies and contributes to an overall sensitivity of 89 dB. Especially in high-quality vehicle audio systems that prioritize sound fidelity and dynamics, paper as a diaphragm material is an excellent choice.

What magnet structure does the Heritage Sub use?

The Heritage Sub uses a ferrite magnet structure known for its robust and consistent performance. Ferrite magnets provide a strong magnetic field strength necessary to efficiently drive the large voice coil and paper diaphragm. This magnet structure also supports the generation of a consistent frequency response from 30 Hz to 500 Hz and effectively contributes to the solid and dynamic sound character of the Subwoofer. Combined with its impedance of 4 Ω, the ferrite magnet structure is optimal for integration into various audio systems.

What performance features distinguish the Heritage Sub?

The Heritage Sub features an RMS power of 200 watts, allowing it to deliver powerful and precise bass. The nominal impedance is 4 Ω, which facilitates integration into standard amplifier systems, while the sensitivity of 89 dB ensures efficient conversion of electrical energy into acoustic power. The frequency response ranges from 30 Hz to 500 Hz, accurately reproducing both deep bass and clear mid frequencies. These performance features make the Heritage Sub a versatile and powerful subwoofer.

How should the Thiele-Small parameters of the Heritage Sub be interpreted?

The Thiele-Small parameters of the Heritage Sub are crucial for predicting its behavior in enclosures. The Fs is at 31.41 Hz, allowing for deeper bass resonance. The Qms of 4.95 and Qes of 0.59 result in a Qts of 0.53, meaning the Sub can operate efficiently across a wide range of enclosure volumes. The Vas of 23.48L indicates the 'equivalent air volume' that the diaphragm can claim, while the Bl value of 14.93 measures the motor strength of the driver. These parameters are essential for optimal enclosure design.

What is the significance of the sensitivity of 89 dB in the Heritage Sub?

The sensitivity of 89 dB in the Heritage Sub is a measure of the achieved volume in relation to the input power. Higher sensitivity means that the Subwoofer requires less amplifier power to reach the same volume as a Sub with lower sensitivity. In practical applications, this leads to a more efficient use of amplifier resources and can be particularly advantageous when power reserves are low. It also allows for a wider selection of amplifiers to optimally drive the Sub.

How do I properly install the Heritage Sub?

When installing the Heritage Sub, the dimensions of 250 mm are crucial to ensure that the enclosure is correctly sized. It is important that the enclosure volume takes into account the Vas value of 23.48L. The impedance of 4 Ω must be compatible with your amplifier to ensure optimal performance. Additionally, the installation location should be chosen so that the ferrite magnet structure does not experience restrictions from surrounding materials. A firm and stable mounting frame is important to avoid unwanted vibrations.

How does the frequency response from 30 Hz to 500 Hz affect the sound of the Heritage Sub?

The frequency response from 30 Hz to 500 Hz in the Heritage Sub covers a wide range of low-frequency sounds, which is essential for reproducing deep and mid-bass frequencies. The low frequency threshold of 30 Hz ensures that even very low tones are reproduced cleanly and with strong punch, which is extremely important for playing music genres that emphasize strong bass. The upper range of the frequency coverage also allows for a clean handover to midrange and tweeters, harmoniously rounding out the sound profile.

Which car brands are compatible with the Heritage Sub?

The Heritage Sub from Quartorigo fits a variety of common vehicle brands and models due to its dimensions of 250 mm and standard impedance of 4 Ω. When installing, it is important to consider the size of the available speaker openings and the supported enclosure volume. Models that provide enough space for a 10-inch Subwoofer are generally compatible. While specific vehicle recommendations should be checked on a case-by-case basis, it fits many well-known brands as long as the mentioned technical specifications of the vehicle can be met.
