The Tang Band SW8622‑0 is an active in-wall audio system designed for flush integration, leveraging 2-way architecture to deliver broad spectrum in compact format. Integration of passive radiator tuned to 75 Hz extends bass response, compensating constraints linked to recessed volume while maintaining coherent tonal balance. This design also groups amplification and power supply directly on module, enabling simplified implementation without external electronics.
Intended for fixed installations (wall distribution, discrete integration in residential or professional environment), it combines Bluetooth reception and controlled directivity, enabling efficient coverage of listening zone from single point. This approach extends into its in-wall format, facilitating integration into existing wall installation.
