Our flagship HD6 powered speaker system represents a major milestone for Audioengine and shows just how far we've come in 10 years. Featuring built-in amplifiers that really pack a punch as well as analog and digital inputs including aptX Bluetooth and optical, the HD6 is not just another great-sounding pair of Audioengine powered speakers, but a complete audio system. Easy to set up, simple to use, and designed for the way people listen to music today. We've included features from some of our best-selling products making HD6 quite possibly the most versatile powered speaker available. Stream TIDAL, Spotify, Pandora, YouTube - or any streaming service or media player - wirelessly from your smartphone, tablet or computer. For the highest resolution connect to the optical input, which is perfect for network music players. It can also be used to connect any component with an optical output, including your TV system. You can also connect your favorite turntable or a subwoofer, so no matter how you connect and listen, HD6 has you covered. The HD6 was designed first for performance, but speakers also need to look great, right? The furniture-grade wood veneers and detachable magnetic grills give the HD6 a look and feel of old-school elegance that blends with any decor. Available in Satin Black for your stealth system as well as Walnut and Cherry wood finishes at no additional cost if you want to really show them off. Built-in power amplifiers save space and eliminate the need to connect HD6 to a stereo receiver or external power amp. Simply plug the left speaker into a power outlet and connect the included speaker wire from the left to the right passive speaker. All internal components of the HD6 are designed and tuned together, so you'll get Audioengine's Signature Sound and a much more efficient system than traditional separate passive speakers and amplifiers.
