Audioengine HD4 Next Gen Home Music System: Overview
The Audioengine HD4 Next Gen is a pair of compact powered speakers. They stream from your phone over Bluetooth or connect by cable to a computer or turntable.
- aptX Adaptive Bluetooth: The speakers stream 24-bit audio and adjust the bit rate in real time. So music stays clear, with fewer dropouts as you move around.
- Built-in DAC: Over USB-C, the internal 24-bit DAC bypasses your computer’s audio chip. As a result, desktop listening gets a cleaner signal.
- Turntable-ready inputs: The RCA and 3.5mm inputs stay active alongside Bluetooth, so a turntable can stay plugged in. Some turntables need a separate preamp.
- Room-filling drivers: Each speaker pairs a 4-inch aramid fiber woofer with a silk dome tweeter, driven by a Class AB amp with 120W peak total.
- Headphone amp: A built-in headphone output lets you listen privately.
At 9 inches tall, the HD4 Next Gen fits on a crowded desk and fills the room with stereo sound.
