Inspired by the Way You Listen

Rounding out Audioengine’s legacy HD-series, HD4 wireless speakers offer versatile, high-fidelity audio ideal for smaller spaces. A premium-powered, two-speaker setup that offers excellent music reproduction and surrounds you with a sense of presence that most compact systems often miss.

Bringing home the high-performance technology inside our HD6 along with the convenience of our modestly-sized HD3, the HD4 is a perfect blend of the power you love to feel and the modern functionality you depend on. Thoughtfully wrapped in precision-tuned, hand-built wood-veneer cabinets.

Designed to take on space limitations, the HD4 is the perfect upgrade where surfaces are minimal but performance and convenience can’t be compromised. As handsome as they are compact, the HD4 will easily fit in any small living space and blend in with any decor.

Purpose-built for versatility, the HD4’s modest design does little to prepare listeners for such expansive soundstage and crystal-clear imaging. The difference between listening to your music and hearing ALL of it...with more room for dancing.
