Khui thùng và trải nghiệm loa công nghệ B&O BeoPlay A9 thế hệ 4, phiên bản đặc biệt.

Bang & Olufsen mới đây vừa cho ra mắt mẫu loa Bluetooth mới Beoplay A9 4th Gen với thiết kế 7 driver đồng thời có hỗ trợ Google Assistant. Sản phẩm vẫn giữ lại kiểu dáng truyền thống của A9, tuy nhiên được tích hợp nhiều tính năng mới mẻ hơn, trong đó gồm việc tương thích với cả Apple Airplay 2 và Google ChromeCast.

Mỗi driver loa sẽ được đánh bằng mỗi amplifier khác nhau: 1 x 400 watt class D cho bass, 2 x 200 watt class D cho driver trung âm, 2 x 200 watt class D cho driver toàn dải và 2 x 150 watt class D cho dải treble.

Thêm vào đó, B&O Beoplay A9 4th Gen còn sở hữu tính năng tự điều chỉnh âm thanh theo phòng nghe, cho âm thanh ổn định dù được đặt ở bất cứ vị trí nào trong phòng. Mặt trước loa được phủ lụa để tăng tính thẩm mỹ tổng thể cho sản phẩm.
