AW-6.5A by DD Audio

The DD Audio AW-6.5A, a 6.5-inch midwoofer, represents innovative driver technology and efficient energy transfer. It offers an impressively rigid support frame through its open aluminum cast basket and a well-controlled, linear sound thanks to its inverted butyl rubber surround and composite spider. The integrated high-energy dual shorting ring motor, tuned to a 1.5-inch voice coil made of copper-clad aluminum wire with a Kapton former, ensures optimal efficiency and power handling. Additionally, it impresses with the neutral sound of a paper cone and the precision that only an ultra-stiff aluminum cone can provide. This results in a wide range and efficient energy transfer. DD Audio sets a new standard for midwoofers with this model.

Frequently Asked Questions about AW-6.5A


What are the main features of the DD Audio AW-6.5A?

The AW-6.5A from DD Audio is a 6.5-inch midbass driver that provides structural rigidity through its cast aluminum basket. The speaker uses an inverted butyl rubber surround and a composite spider to achieve linear sound reproduction. It features a high-energy dual shorting ring motor combined with a 1.5-inch voice coil. This voice coil is made of copper-clad aluminum wire and is mounted on a Kapton former. The aluminum cone and butyl dust cap provide acoustic damping. The driver is tuned to a frequency response of 50 Hz to 20 kHz.

What are the technical specifications of the AW-6.5A?

The DD Audio AW-6.5A has an RMS power of 75 watts and a peak power of 200 watts. The impedance is 4 ohms, and the voice coil measures 1.5 inches. The frequency response ranges from 50 Hz to 20 kHz. The mechanical and electrical quality factors are Qms 4.835, Qes 0.452, and Qts 0.413, with Vas at 14.714 liters. The sound pressure level at 1 watt/1 meter is 91 dB. Other key technical specifications include a resonance frequency of 62 Hz and a 20 mm thick ferrite magnet motor.

How is the structure and design of the AW-6.5A configured?

The construction of the AW-6.5A includes an open aluminum die-cast basket that provides structural stability. The speaker features an ultra-rigid aluminum cone to minimize distortion and enhance accuracy. The combination of butyl rubber surround and composite spider allows for precise diaphragm control. The 1.5-inch voice coil is made of copper-clad aluminum wire on a Kapton former. Additionally, the high-energy dual shorting ring motor is essential for efficiency and durability. The acoustically treated structures, including the butyl dust cap, help reduce unwanted vibrations.

What advantages does the aluminum cone of the DD Audio AW-6.5A offer?

The aluminum cone of the AW-6.5A offers exceptional strength and low weight, contributing to high sensitivity and excellent sound precision. Aluminum is known for its rigidity, which minimizes distortion at high volumes, thus allowing for clearer reproduction of mid and low frequencies. Combined with the butyl dust cap, the cone provides effective acoustic damping. This achieves an optimal balance between rigidity and damping, delivering outstanding sound quality at both low and high volumes.

How does the voice coil technology affect the performance of the AW-6.5A?

The 1.5-inch voice coil of the DD Audio AW-6.5A is made from copper-clad aluminum wire on a Kapton substrate, which increases both heat resistance and efficiency. This voice coil design allows for precise control of the diaphragm movement, resulting in accurate sound reproduction. The high-energy double shorting ring motor achieves effective heat dissipation and improves durability, ensuring consistent performance at high volumes. The use of Kapton as the substrate material ensures thermal stability and minimizes the risk of thermal distortion.

What features does the ferrite motor of the AW-6.5A have?

The AW-6.5A features a high-energy ferrite motor that is 20 mm thick and offers exceptional magnetic properties. This ferrite motor is designed to ensure a stable and strong magnetic field distribution, leading to more efficient conversion of electrical to mechanical energy. The compact size of the motor contributes to design flexibility and allows for easy integration into various speaker enclosures. The triple shorting ring implemented in the motor reduces rotational losses and optimizes performance by minimizing electromagnetic distortion.

What is the compatibility of the DD Audio AW-6.5A with car models?

The AW-6.5A has an outer diameter of 6.5 inches and a mounting diameter of 14.6 cm, allowing compatibility with a variety of vehicles. The mounting depth is 7.3 cm, so a prior check of the door or enclosure installation conditions in the car is necessary to ensure a proper fit. Due to its universal dimensions, it can be integrated into most vehicle speaker spaces, making it an excellent choice for car enthusiasts seeking a significant sound improvement.

What role does the spider play in the construction of the AW-6.5A?

The composite spider used in the AW-6.5A is crucial for the suspension and control of the diaphragm movement. Its task is to keep the voice coil centered while allowing for flexible movements. The flat-woven, spider-shaped lamella cables support mobility and reduce mechanical losses. This structure enables stable and tailored diaphragm control, which is essential for precise sound reproduction. Through its acoustically optimized design, the spider helps minimize unwanted noise and enhances the overall efficiency of the speaker.

What is the significance of the geodesic pattern of the aluminum grill?

The machined aluminum grill of the AW-6.5A with its geodesic HB pattern offers both protection and aesthetic value. This pattern is not only a design element but also plays a role in distributing mechanical stresses, improving the grill's durability. It helps protect the cone from physical damage while minimizing reflections that could affect the sound. The geodesic design ensures that acoustic transparency is maintained while structural integrity is guaranteed, contributing to an uninterrupted sound performance.

Which crossover is compatible with the AW-6.5A?

The AW-6.5A is compatible with the optional passive 2-way crossover CX02 from DD Audio. This crossover allows for precise separation and distribution of audio signals to the corresponding speaker drivers. The CX02 supports sound optimization by adjusting the crossover frequencies to improve frequency response and sound balance. A correctly set up system leads to a smooth overlap between midrange and tweeters, creating a complete and harmonious sound library. The compatibility of the AW-6.5A with the CX02 offers the possibility of a flexible and tailored audio installation.
