| The latest offering from JohnBlue Audio is the best desktop audio speaker we've heard (and reviewers agree)! I have a three dimensional sound stage stretching deep behind the plane of the speakers (and monitor) - the effect is quite startling and thoroughly addictive!
... they are doing things I've not heard before. My usual computer system uses a small active sub and this was utterly superfluous with the JB3's.

The JohnBlue JB3 performs best in small-room, near-field listening environments such as a bedroom or office. It's small size makes it a little giant on the desktop.
Paired with the T20U, the JB3 makes exceptional Hi-Fi setup for your computer! The JB3 features an amazing 3" full-range driver that sports a special resin-cast wave guide and cone, pioneered and developed by JohnBlue.Features
- Single full-range driver means no crossover!
- Bass reflex design
- 1mm thick Piano Black Gloss finish
- Pure solid-core copper wiring
- Anti-fungus treated cone
- Resin-cast wave guide
- Proprietary Speaker Binding Posts CNC machined by JohnBlue using pure red copper plated over gold-plated brass
Despite
a conservative rating of only 87dB sensitivity, the JohnBlue JB3 pairs
extremely well with T-amps. They reproduce music with incredible
dynamics and volume.
Music is full-bodied, voices are delivered with clarity and smoothness. Imaging is precise yet wide and notes flow naturally as if the artist were in front of you. I
can now confidently come forward and wholeheartedly endorse the JB3.
Kudos to Tommy Wu, the young master of the full-range driver. (And I
must thank him for having the gumption to tell me not to use my
subwoofers.) David Kan 6moons.com
From the 6moons review: The 3" naked driver has a frequency response of 90Hz to 21kHz. When coupled to our bass reflex cabinet, it extends to 50Hz. The high frequency actually approaches the realm of superior tweeters, reaching 21kHz at -1dB and 23kHz at –6dB. In terms of bass performance, we must bear in mind the physical limitation of a 3" driver.
Even so, the JB3 can deliver bass extension beyond expectation if you follow these three simple rules: (1) A good solid foundation. (2) Good synergistic speaker cable. (3) Place the speakers with the bass reflex ports to the inside. The speakers should be positioned 150 - 180 cm apart, 180 - 220 cm from the imaginary middle point between the speakers to the listening positionSpecifications Efficiency
