DB Technologies FIFTY System with 2 118 Subs and a 410Top

Get a Scalable, High-SPL PA System With the dBTechnologies Fifty Top + Fifty Sub

The dBTechnologies Fifty Line system is built for flexible, tour-ready deployment—ground stack one or two Fifty Tops on Fifty Subs, or fly the Fifty Tops using the dedicated flybar. With powerful onboard amplification, FIR-tuned DSP, and full network control via Aurora Net, this Top/Sub combination delivers clean, consistent coverage and serious output for venues, events, and installations.

• Scalable deployment: ground stack or fly (single or paired Fifty Tops)
• Recommended stack: 1x or 2x Fifty Tops over 2x Fifty Subs for optimal performance
• Aurora Net network control for EQ, delay, processing customization, and real-time monitoring
• On-board rotary encoder with quick-recall presets
• Linear Phase FIR Filters for pristine vocal reproduction and improved coherence when pairing Tops
• High output with efficient power usage through optimized transducer “radiating real estate”
• Matched design language and processing across the Fifty Line range

Scalable System Deployment

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 to double output capabilities. The waveguide is designed to minimize interferences between two Fifty Tops stacked together—simply flip one unit upside down for seamless coupling.

When the venue requires wider coverage, fly or ground stack several Fifty Tops side by side to expand horizontal dispersion to the desired amount.

Flying Fifty Tops is just as easy as stacking them: the flybar design fits either one or two-height Tops without the need for different adaptors, and the transport dollies are optimized for smooth setup and tear down. The on-board rotary encoder provides quick-recall presets to adapt the system to basic applications.

Remote Control

Fifty Line features complete network capability via Aurora Net control software, allowing EQ, delay and processing customization along with real-time monitoring of the system in use.

Impressive Performance Through Acoustic Innovation

Fifty Line is designed to achieve the highest possible SPL levels while keeping overall power consumption low. This performance is achieved by maximizing the radiating surface area of the transducers on-board the Fifty Top.

Each Fifty Top is comprised of 4x 10-inch woofers and 2 compression drivers, carefully tuned for fidelity even at very high working loads.

FIR Filters On Board

In the digital audio domain, FIR (Finite Impulse Response) filters operate on frequency response while maintaining a linear phase. dBTechnologies tuned Fifty Line using Linear Phase FIR Filters to optimize overall system performance with pristine vocal reproduction and improved high-frequency coherence when two Fifty Tops are paired in head stack mode.

A Mighty Companion

To complete a Fifty Line system in any deployment, Fifty Sub is the perfect match. Designed to pair with Fifty Tops in ground-stacked configurations, Fifty Sub shares the same design language, DSP platform, and Class-D 1600W RMS power amplifier approach found across the Fifty Line family.

dBTechnologies recommends stacking 1x or 2x Fifty Tops over 2x Fifty Subs for optimal performance.
