The new J series is a technologically advanced range of products that improves on the performance of the previous Jolly line.  The new J series is a competitive, value for money range of speakers.

The range is based on the development of three new high efficiency class-D amplifiers with power specifications of 350 + 100W

These amplifiers have been designed 'from the ground up' in FBT’s R&D laboratories.

The largest amplifier model that equips the J 15A and J 12A has a switch mode power supply as well as a digital signal processor with 4 pre-sets.
