JBL One Series 104 vs Audioengine HD4

Last updated: October 1, 2026

Short answer: the Audioengine HD4. It ranks #83 of 100 powered bookshelf speakers by sound quality (rated 3.2/5) at $429 and is still sold new; the JBL One Series 104 ranks #93 (rated 2.8/5) and is discontinued, so it is only an option used.

JBL One Series 104 vs Audioengine HD4

The case for the JBL One Series 104: ASR’s powered-system measurement gives -3dB bass around 72Hz, and the compact coaxial layout is convenient for a small desk. It has an adjustable EQ, which the Audioengine HD4 lacks. The tradeoff: Even with the active system measured properly, scores are only 1.36 standalone and 4.08 with an ideal subwoofer.

The Audioengine HD4 is the better-sounding pick. Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. The tradeoff: The compact cabinets suit close desktop listening rather than a large-room system.

Buy the Audioengine HD4. It is rated higher for sound quality, and the JBL One Series 104 is discontinued, so it is only available used.

Pros: ASR’s powered-system measurement gives -3dB bass around 72Hz, and the compact coaxial layout is convenient for a small desk. Its internal equalization is part of the working speaker and should be included when assessing it, rather than judging the passive drivers with that correction bypassed. Measured bass extension of 45Hz (-3dB).

Cons: Even with the active system measured properly, scores are only 1.36 standalone and 4.08 with an ideal subwoofer. The 4.9dB midrange span and a high-frequency cancellation around 7.4kHz indicate significant unevenness; the review also found some vocals bright and irritating. These are results for the original 104, not a verification of the later 104-BT. Discontinued.

Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5) and the Audioengine HD6 (larger bookshelf, ranked higher, rated 3.3/5).

Pros: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. Its modest footprint is useful where larger studio monitors are impractical.

Cons: The compact cabinets suit close desktop listening rather than a large-room system. A separate subwoofer adds cost and space if deeper bass is a priority.
