dB Technologies Active subwoofer, 18" woofer, 1500 W RMS amp

Fifty Line is one of our most straightforward systems: easy transport options, smooth deployment with scalable options, outstanding final result.

Scalable system

The optimal way to deploy fifty line is either ground stack one or two Fifty Tops on Fifty subs, or fly the Fifty tops using the dedicated flybar.

The unique design of Fifty Top allows up to two units to be vertically coupled seamlessly, in order to double the output capabilities. The waveguide is designed to minimise interferences between two Fifty tops stacked together: all you need to do is flip one of the two upside down.

When the venue requires a wider coverage, it’s easy to either fly or ground stack several Fifty Tops side by side, spreading the horizontal dispersion of the PA system to any desired amount.

Flying Fifty tops is just as easy as stack them: the flybar design fits either one or two-height tops, without he need to own different adaptors, and the dollies designed for transport are optimised for a smooth setup and tear down of the system. Nevertheless, the on-board rotary encoder provides for several quick-recall presets to adapt the system to basic applications.

Remote Control

Fifty Line also features complete network capability via Aurora Net control software which allows EQ, delay and processing customisation and real time monitoring of the PA system in use.

A mighty companion

To really complete a Fifty line system in any deployment you’ll need Fifty sub.

this cabinet has been designed to perfectly pair with Fifty tops in ground stacked configurations, sharing the same design, as well as same DSP and Class-d 1600W RMS power amplifier.

dBTechnologies always recommends to stack 1x or 2x Fifty tops over 2x Fifty sub for an optimal performance.
