JohnBlue JB3 & KingRex T20U

A simple package which pairs the award winning KingRex T20U with the critically acclaimed JohnBlue JB3. The combination brings together the tube-sounding Class-D amplifier with a full-range driver speaker design, this is a system guaranteed to bring out the character and emotion of your music.

The T20U features the Tripath TA2020 chip which is able to produce more power than most ‘T-Amps’ already on the market. It's suitable for loudspeakers with 86~90db sensitivity and can effortlessly give more than enough sound for the average room.

Music is detailed, crisp and definitely not bass shy. Soundstage is wide with a lot of space around instruments and vocals. Don’t let its small size deceive you! The KingRex T20U is one serious amplifier.

All this is enclosed in a tiny but elegant enclosure of anodized aluminum, the plugs at the back are all gold plated. Build quality is strict and very simple with minimal features and straight to the point circuitry.

The bass reflex cabinet is contructed from MDF and finished with a 1mm thick Piano Gloss lacquer. Internally the JB3 uses proprietary damping material and pure solid core copper wiring. Because the JB3 uses a single full-range driver, this means that there is no crossover. Less parts in the signal path means more purity!

The JB3 is able to reproduce music with incredible dynamics and volume, don't be fooled by the size! Music is full-bodied like a nice red wine, voices are delivered with clarity and smoothness. Imaging is precise yet wide and notes flow naturally as if the artist were infront of you.
