4-inch high-fidelity passive speakers Hi-Fi audiophile-grade bookshelf speakers home theater surround sound home audio


Product Description

This 4-inch high-fidelity passive speaker, as a Hi-Fi audiophile-grade bookshelf speaker, can bring an excellent auditory experience whether used for home theater surround sound or daily home use. Its various designs highlight professionalism and quality.

In terms of treble performance, it is equipped with a 3-inch silk dome tweeter unit, which can present a crisp and clear high-frequency response. Treble is the soul of a sound system, and key factors such as its timbre, transient texture, dynamic compression, and distortion are well controlled here, laying a high-quality foundation for the overall sound effect.

For the mid-bass part, a newly designed 4-inch mid-bass speaker is adopted. It is equipped with a high-strength damping PP diaphragm, combined with a long-stroke and high-power design, and has strong large dynamic low-frequency output capability. At the same time, with the energy-absorbing rubber surround, it can ensure low-frequency extension down to 40Hz, making the bass performance more impactful.

It is worth mentioning that this speaker is tuned with the LMS electroacoustic analysis system. LMS is a professional tool widely used in industrial audio, home audio, car audio systems, and audio engineering acceptance, ensuring the accuracy of the speaker's performance.
In terms of crossover, a professional 2-way crossover is used, which has been carefully tuned. It enables the treble to show rich details and better high-frequency extension, while making the sound more delicate and smooth, and transitioning naturally with the mellow midrange, improving the harmony of the overall sound effect.

To enhance the low-frequency performance, the speaker is equipped with a large-caliber hyperboloid port tube. It can make the air flow smooth without sudden changes. Compared with ordinary port tubes, it can effectively avoid air flow whistling, make the sound purer, and the low-frequency extension more thick.

The cabinet is constructed with high-strength MDF boards as thick as 12mm, and a single cabinet weighs 2.6kg. The thick boards can effectively avoid cabinet resonance, providing a solid guarantee for the purity of the sound effect.

In addition, both cabinets are covered with 20mm thick professional wave-peak sound-absorbing cotton for sound attenuation treatment, which can avoid resonance interference and reduce the impact of standing waves on sound quality. The binding posts are made of pure copper gold-plated material, with smaller contact resistance, which can effectively reduce signal transmission loss and further ensure the purity of the sound quality.
