Every Harman Kardon Speaker Ranked

Last updated: August 12, 2026

This page lists all 13 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.

Boombox Size Portable Bluetooth Speakers

Ranked #3 of 73 in Boombox Size Portable Bluetooth Speakers - Harman Kardon Go + Play 3: $385 Amazon

Harman Kardon Go + Play 3 ranking card

Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Go + Play2.

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.
