- TRE-108A

The Tensor Active models use the same cabinets and components as the passive systems, but feature superbly efficient, light weight 500W Class D power amplifiers driving the woofers, with separate 50W Class A/B amps driving the HF units. Active crossovers and subtle equalisation ensure the cabs, amps and drivers are perfectly suited to each other, and outperform expectations. Tensor Active cabs don


Incredibly compact, but with a performance and specification that outdoes many bigger cabs. 180W RMS power handling and exceptional performance from the high power 8

PA woofers

Many aspects must be considered in PA woofer design: Is it for a sub or a front-of-house cab? If front-of-house, what compression driver will it be used with? What size and type of cabinet must it suit? How many drivers will be in the cab?

Tensor Range Speakers

The Tensor range of cabinets feature high efficiency 1” exit compression drivers with 44mm voice coils (except TRE-108, which uses a 1” exit / 25mm coil compression driver with Neodymium magnet). These high specification drivers perfectly complement the moulded horn flare giving great clarity and dispersion across the high frequency band. Tensor woofers all feature Kevlar reinforced felted cones and large diameter high power rated precision voice coils. The drivers are designed for high efficiency, giving better transient response, clarity and reliability whilst reducing thermal compression issues.
