B7741 JENSEN Electro Dynamic Field Coil Speaker

The Jensen B7741 FR8S electro-dynamic field coil speaker is a high-performance audio component designed for discerning audiophiles and music enthusiasts. This speaker employs the classic field coil technology, which was once the industry standard before the widespread adoption of neodymium magnets in speakers.

The B7741 FR8S boasts a powerful neodymium magnet structure, which drives a 1-inch voice coil. The use of a field coil instead of a conventional permanent magnet allows for greater control over the speaker's magnetic field. This results in improved dynamic response, faster transient response, and enhanced detail and clarity in the midrange frequencies.

The speaker cone is made of a proprietary paper pulp material, which provides excellent stiffness and damping properties. The cone's shape is engineered to minimize distortion and ensure accurate and efficient energy transfer from the voice coil to the air. The speaker also features a rubber surround that ensures a reliable and stable mechanical mounting and provides the necessary flexibility for the cone to move freely.

The B7741 FR8S employs a classic screw-in binding post design that allows for easy and secure termination of speaker wires. The binding posts are made of high-quality brass, ensuring reliable electrical contact and corrosion resistance. The speaker's impedance is rated at 8 ohms, making it compatible with a wide range of audio systems.

This speaker's frequency response is rated from 50 Hz to 20 kHz, ensuring that it covers the entire audible frequency range. Its maximum power handling is 15 watts RMS, making it well-suited for use in high-fidelity audio systems, as well as in professional audio applications such as live sound reinforcement and recording studios.

In summary, the Jensen B7741 FR8S electro-dynamic field coil speaker is a high-performance audio component that delivers exceptional detail, clarity, and accuracy in the midrange frequencies. Its classic design, combined with modern engineering and materials, makes it a popular choice among audiophiles and music professionals. Whether you're building a high-end stereo system or looking for a reliable speaker for your live sound setup, the B7741 FR8S is sure to impress.
