50% off/$150

As part of its wider salve event on TVs, speakers, and more, Woot is offering Harmon Kardon’s Onyx Studio 9 portable Bluetooth speaker for $149.95 Prime shipped (a $6 delivery fee will apply otherwise). This model originally launched at $300 and has recently been selling for closer to $210 through third-party listings at Amazon, so today’s deal takes a straight 50% off the original price. Discounts have also been relatively scarce on the Onyx Studio 9 this year, especially after stock dried up at Amazon, and today’s deal marks one of the lowest prices we’ve tracked for it in 2026. It remains a pretty good option to consider if you’re looking for a reliable portable speaker with stereo sound and a built-in battery, and you can learn more about it in detail below.

The Harman Kardon Onyx Studio 9 is a portable Bluetooth speaker built for home listening, but its integrated battery also makes it easy to move between rooms or take outside. Its rounded design and built-in handle give it a more polished look than many other portable speakers out there, and it also offers a stereo setup for a fuller, wider sound. One of the highlights here is its support for automatic self-tuning, which adjusts the audio based on where the speaker is placed. It also supports Auracast, allowing you to connect it with other compatible speakers for a larger multi-speaker setup.

Elevate your everyday listening to an extraordinary sound experience with the Harman Kardon Onyx Studio 9. This elegant wireless Bluetooth® movable home speaker delivers superior audio performance with crystal-clear vocals, bright highs, and deep bass that make your favorite music feel thrillingly immersive. Constant Sound Field technology widens the soundstage and improves the clarity and detail of your music. The substantial integrated handle (made with 90% recycled aluminum) and built-in battery with 8 hours of playtime make the Onyx Studio 9 easy to move with you in and around your home, and a built-in USB port recharges your device while you enjoy your music. And thanks to automatic self-tuning, it always delivers the best possible sound performance wherever you set it down.
