JBL One Series 104 - ranked #64 of 68 Medium Size Powered Bookshelf Speakers · Editor's rating 2.8/5

#64 JBL One Series 104: $129 per pair Discontinued eBay

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.

How it compares: Just above it: Midiplus MI5 II - $40 more, 40W more output power. Just below it: Fluid Audio FX50 V2 - $20 more, 30W more output power.
