FBT VHA 118 SN | 18in - 143dB | Powered Ground Subwoofer

Powered Ground Subwoofer

FBT VHA 118 SN is a direct-radiation powered ground subwoofer designed to reinforce and extend the low-frequency response of the HORIZON VHA system. Its bass-reflex design, high-excursion 18-inch woofer, and high-output Class D amplification make it well suited for live sound environments where deep, controlled bass and high SPL are required.

FBT VHA 118 SN Competitive Differences

• 18-inch high-excursion B&C woofer with 4-inch voice coil for powerful low-frequency performance
• Designed for HORIZON VHA system integration, including ground stack compatibility with VHA 406ND and VHA 112SND models
• Supports cardioid preset configurations for improved control of rear sound pressure
• Built-in TCP/IP network interface with AES70 compatibility for remote control via INFINITO System Management Suite
• Rugged 18mm birch plywood enclosure with anti-scratch finish, protective grille, and caster-ready design

FBT VHA 118 SN Description

The FBT VHA 118 SN is engineered as a high-performance subwoofer for professional touring, installed sound, and scalable array-based reinforcement systems. It uses a single 18-inch long-excursion woofer in a bass-reflex cabinet to deliver substantial low-end energy down to 30Hz, making it an effective solution for extending the impact and depth of compatible VHA systems.

The enclosure is optimized using BEM-type acoustic simulations to reduce port turbulence and cabinet resonance, helping the subwoofer maintain strong output with controlled performance. Its cabinet is constructed from 18mm birch plywood and finished in a durable black anti-scratch coating, while the front is protected by a powder-coated perforated steel grille with protective fabric.

For practical deployment, the cabinet includes multiple aluminum handles, provision for four 100mm swivel casters, and two M20 stand sockets for horizontal or vertical use. Integrated hardware also supports ground stack configurations in conjunction with compatible VHA models, making the unit suitable for professional rental inventories and fixed system deployments.

Onboard control is handled through an OLED display and push encoder, giving users direct access to settings and presets. The VHA 118 SN is also designed for remote system management through FBT INFINITO software over TCP/IP. According to the provided product information, the VHA 118 SN shares the same core characteristics as the VHA 118 SND version, but does not include Dante functionality.
