The DOUBLE FOUR is the pinnacle of micro bass amps.
Phil Jones Bass are back with a new driver design, acoustic loading and the latest digital amplifier technology, this tiny bass combo may be designed as a practice amp but continues to amaze everyone with the great PJB signature bass tone. From a cabinet the size of a jewel box, this seems to defy the laws of physics.

Each one of these 4” speaker is fed with its own Pulse Width Modulation (PWM) amplifier. PWM amplifiers are extremely efficient compared to the traditional analog solid state amplifiers, converting electrical energy for use on the speakers. Since the amp is running at lower working temperature, the Phil Jones Bass DOUBLE FOUR will give years of service long after other amps have faded away.
To maximise its tiny cabinet enclosure, we designed a custom Rectangular Auxiliary Low Frequency Radiator (RALFR®). RALFR® is a pneumatically coupled radiator loaded to the rear of the two 4 inch speakers that operates at the lowest bass frequencies only. It augments the output of the loudspeakers at frequencies from 30 to 150 Hz. It also reduces the cone excursion of the speakers, so power handling is greatly improved. The cabinet is also heavily braced internally and lined with acoustic damping materials. This damping prevents cabinet coloration that can interfere with the true sound of your instrument. The Phil Jones Bass DOUBLE FOUR is the most realistic amplification of your instrument.
