B-228 Dual 18" Subwoofer

B-228 DUAL 18" SUBWOOFER

It brings a silky smooth low-frequency flow and a deep, layered sound performance

THE LIMIT OF HEARING

Its low-frequency extension can reach an extremely low frequency range, approaching the boundary of human auditory limits, providing a truly "perceptible and audible" bass experience.

PURE LOW FREQUENCY

B-228 Acoustic System features an optimized bass-reflex structure with dual symmetrical bass ports. Its rational layout, refined through CFD fluid dynamics simulations, significantly reduces airflow turbulence noise and wind distortion. This design not only improves low-frequency airflow efficiency but also enhances dynamic response speed and bass clarity, delivering purer, more natural, and more elastic low-frequency output.

THE EXPRESSION OF VOICE ATTITUDE

The B-228 is not merely a subwoofer; it is also an expression of a sound attitude: an unwavering dedication to sound quality, a reverence for details, and a deep concern for user experience.

THAT'S RIGHT

Choosing the B-228 means choosing a commitment to quality, an active pursuit of an outstanding auditory experience, and the beginning of a brand-new auditory journey.
