The new J series is a technologically advanced range of products that improve 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 for the J 15A & J 12A, 200 + 50W for the J 8A and 80 + 40W for the J 5A.
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 have a switch mode power supply as well as a digital signal processor with 4 presets. The J 8A and J 5A amplifiers have toroidal transformer power supplies. The J 8A has a digital signal processor with 2 presets, whilst the J 5A has analog signal processing. The speakers have been completely redesigned, introducing the technological developments of recent years to achieve a far superior efficiency and linearity.
