Harman Kardon Speaker Rankings and Reviews

Coverage note. Speaker Ranking currently covers 14 Harman Kardon models across portable bluetooth speakers. These are the products in our database, not a complete list of everything Harman Kardon makes.

What this page covers. The Harman Kardon models ranked here span portable bluetooth speakers, including Harman Kardon Go + Play 3, Harman Kardon Onyx Studio 8 and Harman Kardon Onyx Studio 6. Use each model’s category position to compare it with alternatives of the same size and use case.

This page lists all 14 Harman Kardon speakers ranked on this site across portable bluetooth speakers. Each model is shown in the category where it competes, with its current rank and the size of that ranking.

Use the category position rather than the brand name alone: speakers from the same manufacturer can perform very differently by size, price and product family.

Prices on this page were last checked October 1, 2026 at 6:23 PM UTC. Product prices and availability are accurate as of that date/time and are subject to change; the price and availability shown on Amazon at the time of purchase will apply to the purchase of this product.

Medium Size Portable Bluetooth Speakers

Ranked #23 of 150 in Medium Size Portable Bluetooth Speakers - Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay

Older model: the Harman Kardon Luna (ranked lower, rated 4/5).

Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.

Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).

Ranked #24 of 150 in Medium Size Portable Bluetooth Speakers - Harman Kardon Luna: $290.99 Amazon eBay

Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5.

Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).

Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.

Boombox Size Portable Bluetooth Speakers

Ranked #3 of 89 in Boombox Size Portable Bluetooth Speakers - Harman Kardon Go + Play 3: $385 Amazon eBay

Older model: the Harman Kardon Go + Play 2 (ranked lower, rated 3.9/5).

Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Go + Play2. An aux input, a built-in microphone, a power bank function, stereo pairing and hidden button combinations for adjusting bass and treble. Measured bass extension of 35Hz (-10dB).

Cons: Just a little over half as loud as the higher rated boomboxes. Only 8 hours of battery at medium volume. No water rating.

Setup: Use the hidden EQ modes to adjust the bass up when outside and down when inside. To adjust bass, quickly press the bluetooth and volume down buttons together, the number of light flashes tell you what mode you’re in. To adjust treble, quickly press the volume up and phone buttons at the same time, the number of yellow flashes on the light tell you what mode you are in.

Ranked #14 of 89 in Boombox Size Portable Bluetooth Speakers - Harman Kardon Onyx Studio 7: $248.90 Amazon eBay

Newer model: the Harman Kardon Onyx Studio 9, ranked lower, rated 4.1/5.

Pros: The addition of dual tweeters gives the Studio 7 a wider, more spacious presentation than older Onyx models. It delivers strong, deep bass, useful large-room volume and can pair with a second Studio 7 for stereo. Measured bass extension of 37Hz (-10dB).

Cons: Consumer Reports finds the bass prominent and boomy, mids hazy, treble slightly smeared and the soundstage congested. Battery life remains only about eight hours, it has no water rating or advanced codecs, and it is not an especially loud outdoor speaker.

Ranked #15 of 89 in Boombox Size Portable Bluetooth Speakers - Harman Kardon Onyx Studio 9: $189.99 Amazon eBay

Older models: the Harman Kardon Onyx Studio 8 (ranked higher, rated 4.1/5), the Harman Kardon Onyx Studio 7 (ranked higher, rated 4.1/5), the Harman Kardon Onyx Studio 6 (ranked higher, rated 4.1/5), the Harman Kardon Onyx Studio 5 (ranked lower, rated 3.9/5) and the Harman Kardon Onyx Studio 4 (rated 3.3/5).

Pros: An elegant 4.2kg living-room portable with a measured 41Hz -10dB bass point, 101dB maximum level, three tweeters, app EQ, stereo pairing and Auracast multi-speaker linking. Reviews praise its balanced, smooth presentation and non-fatiguing treble, making it a more music-focused choice than most party speakers. Measured bass extension of 41Hz (-10dB).

Cons: It has no water resistance, aux input or USB playback, and its eight-hour claimed battery life is short for an outdoor portable. Bass is less deep than some earlier Onyx Studio models, while the slightly recessed mids and rolled-off top end mean it is not the most open or detailed option; it still charges from an AC power cable rather than USB-C.

Newer model: the Harman Kardon Onyx Studio 9, ranked lower, rated 4.1/5.

Pros: Harman Kardon Onyx Studio 6 uses a 120mm woofer, 25mm tweeter and passive radiator. Its 2.94 kg, claimed 8 hours (Manufacturer specified) battery life, IPX7 protection, aux input and up to 96dB make it a practical option for its intended room or portable use. Measured bass extension of 37Hz (-10dB).

Cons: Bass is limited by its 37Hz specification. There is no companion app. No EQ adjustment. Warm tuning with boosted bass, and not as loud as others. Discontinued.

Ranked #24 of 89 in Boombox Size Portable Bluetooth Speakers - Harman Kardon Onyx Studio 5: $499.99 Discontinued Amazon eBay

Newer model: the Harman Kardon Onyx Studio 9, ranked higher, rated 4.1/5.

Pros: The iconic circular cabinet and integrated handle make it an attractive room-to-room speaker. Reviews praise its generous bass, balanced mids and smooth top end at moderate levels, giving it a warm, relaxed presentation for casual indoor music.

Cons: The large bass boost can mask lower-mid detail and make dense mixes muddy. Battery life is only around eight hours at moderate volume, it is not especially loud, and it has no water resistance for outdoor use. Discontinued.
