The TAD TD-4001 Alnico Horn Driver is a high-fidelity loudspeaker component designed for audiophiles and professional sound engineers seeking exceptional sound quality. This driver is characterized by its Alnico magnet and beryllium diaphragm, which work together to deliver accurate, detailed, and musical sound.
The Alnico magnet is a rare and expensive material, known for its strong magnetic field and ability to provide a linear magnetic field over a wide frequency range. This property results in precise and natural sound reproduction, with minimal distortion and excellent dynamic response. The magnet is also relatively lightweight compared to other types of magnets, which helps to reduce the overall weight of the driver and improve its efficiency.
The beryllium diaphragm is a lightweight and rigid material that is renowned for its ability to reproduce even the most subtle and delicate sound details. Beryllium is also known for its low mass and high stiffness, which results in quick and accurate transient response. This property is particularly important for high-frequency sound reproduction, where the ability to reproduce fast transients is crucial for achieving a natural and lifelike sound.
The TD-4001 driver is a horn-loaded design, which means that it is designed to be used in conjunction with a horn loading system. This design approach has several advantages, including increased efficiency, improved directivity, and reduced distortion. The horn loading system also helps to focus the sound energy in a specific direction, making the driver ideal for use in applications where directionality is important, such as live sound reinforcement or home theater systems.
The TD-4001 driver is a 16-ohm unit, which makes it suitable for use with a wide range of amplifiers and audio systems. Its frequency response is rated from 2.5 kHz to 25 kHz, making it a versatile driver that can handle a wide range of audio frequencies with ease. The driver also has a sensitivity of 88 dB, which makes it relatively efficient and able to produce a high output level even with modest amplification.
In summary, the TAD TD-4001 Alnico Horn Driver is a high-performance loudspeaker component that is ideal for audiophiles and professional sound engineers seeking exceptional sound quality. Its Alnico magnet and beryllium diaphragm deliver precise, natural, and musical sound, while its horn-loaded design provides increased efficiency, improved directivity, and reduced distortion. With its wide frequency response, high sensitivity, and versatile impedance rating, the TD-4001 driver is a versatile and capable component that is well-suited to a wide range of applications.
The TAD TD-4001 Alnico Horn Driver with a Beryllium Diaphragm is a high-end audio component designed for professional and audiophile applications. This driver offers several advantages and disadvantages, which can help potential buyers make an informed decision.
Advantages:1. Superior Sound Quality: The Alnico magnet and Beryllium diaphragm combine to deliver exceptional sound quality. Alnico magnets provide a more natural and detailed sound compared to neodymium magnets, while Beryllium diaphragms offer improved rigidity and lighter weight, resulting in faster response times and better transient reproduction.
2. High Power Handling: The TD-4001 can handle high power levels without distortion, making it suitable for use in high-performance audio systems.
3. Wide Frequency Response: The driver's frequency response ranges from 30 Hz to 30 kHz, which covers the entire audible spectrum, ensuring accurate and detailed reproduction of sound.
Disadvantages:1. Cost: The TAD TD-4001 is a high-end audio component, and its price reflects its premium quality. It may be out of reach for budget-conscious buyers.
2. Size and Weight: The driver's large size and weight may pose challenges for those who need to transport or install it in smaller spaces.
3. Complexity: The TD-4001's design is more complex than that of standard drivers, which may require more time and expertise to integrate into an audio system.
Ending Conclusion:The TAD TD-4001 Alnico Horn Driver with a Beryllium Diaphragm is an excellent choice for those seeking the ultimate in sound quality from their audio components. Its superior sound reproduction capabilities, high power handling, and wide frequency response make it a top pick for professional and audiophile applications. However, its high cost, size, weight, and complexity may make it less suitable for budget-conscious buyers or those with limited installation space.
Recommendation:If you are an audiophile or professional looking for the best possible sound quality from your audio system, the TAD TD-4001 is an excellent investment. Its superior sound reproduction capabilities, high power handling, and wide frequency response make it a top pick for those who demand the best. However, if budget or space constraints are a concern, you may want to consider more affordable or compact options.
Details:
Found in a service tech inventory I would imagine it was replacement unit and sat on shelf unused until needed. Found in as shown condition. Unit does have marks and scratches not mint or perfect. Has oem original beryllium 16 ohm diaphragm.
Being sold as is shown condition please see meter and resistance reading the diaphragm is good.
