JBL One Series 104 - ranked #60 of 64 Medium Size Powered Bookshelf Speakers · Editor's rating 2.8/5

#60 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.

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. Just below it: Fluid Audio FX50 V2 - $20 more.
