The Zenith 49-CZ870 Alnico Woofer is a vintage audio component that offers a unique blend of rich, clear sound and classic design. This woofer is part of Zenith's esteemed line of Alnico speakers, which were renowned for their superior sound quality during the golden age of audio.
The Alnico magnet used in this woofer is a key factor in its exceptional sound reproduction. Alnico magnets are made of aluminum, nickel, and copper, and they offer several advantages over other types of magnets. They have a stronger magnetic field than ceramic magnets, which results in better bass response and increased efficiency. Additionally, Alnico magnets produce a more natural, smooth sound compared to other types of magnets.
The cone of the 49-CZ870 Alnico Woofer is made of paper, which was a popular choice for speaker cones in the past due to its ability to reproduce a wide range of frequencies with good clarity and detail. The paper cone is also lightweight, which allows the woofer to respond quickly to changes in audio signals.
The 49-CZ870 Alnico Woofer measures 12 inches in diameter and has a nominal impedance of 8 ohms. It is designed to handle a maximum power of 25 watts, making it well-suited for use in vintage audio systems or as a replacement for original woofers in vintage speakers.
The 49-CZ870 Alnico Woofer comes as a re-cone, which means that it has been reconditioned and re-coned by experienced audio technicians. The process involves carefully inspecting the cone and voice coil, repairing any damage, and then re-coning the speaker to restore it to its original specifications. This ensures that the woofer is in good working order and delivers the best possible sound quality.
In conclusion, the Zenith 49-CZ870 Alnico Woofer is a high-quality vintage audio component that is sure to impress with its rich, clear sound and classic design. Its use of an Alnico magnet and paper cone, along with its re-coning process, make it an excellent choice for vintage audio enthusiasts or anyone looking for a unique and high-performing speaker.
