The Siena 3000W Powered Subwoofer from Turbosound is a front-loaded bass-reflex subwoofer enclosure that is optimally tuned for extended low-frequency response. It features a powerful 18″ low-frequency driver that utilizes an inside/outside wound voice coil for higher magnetic density, better heat dissipation, high power-handling capacity, and improved efficiency. Designed to work individually without a controller, the TSP118B-AN provides high-output FOH performance and is suited for a wide range of music and live sound-reinforcement applications.

Equipped with a lightweight KLARK TEKNIK Class-D power amplifier, the TSP118B-AN provides 3000W of output power in a highly portable and lightweight package. Class-D amplification eliminates the need for heavy power supplies and large heat sinks.

A high degree of control over the loudspeaker system’s performance is managed by KLARK TEKNIK Digital Signal Processor (DSP), which provides dynamic EQ and transparent limiting.

On the rear panel of the amplifier module, you will find a fully featured user interface consisting of an LCD display, with a single rotary encoder for intuitive access to level, EQ, and Feedback Control (FBI). For connecting to powered satellite loudspeakers, the subwoofer features a balanced XLR/jack input and a balanced XLR output .

The TSP118B-AN features Turbosound’s proprietary ULTRANET technology which allows the use of Cat5 cables for transmitting pristine multi-channel audio signals and other information between compatible digital devices, including mixers, I/O stage boxes, powered loudspeakers and personal monitoring systems. Simplified cable routing and ease of setup saves installation time. An on-board USB port provides access for remote control of the TSP118B-AN via a free Windows computer software download from Turbosound.com. Software can be started once per Windows computer and connects to only one speaker at a time. Convenient DSP firmware updates are also available.

Finished in a highly durable semi-matte black paint, the TSP118B-AN is constructed from 1/4″ birch plywood and includes a 35mm pole socket for satellite-speaker mounting, integrated carry handles for convenient transport, and high impact interlocking corners for ground-stacking stability. Mains power input is provided via a Neutrik powerCON connector.
Designed to provide performance for traveling musicians, or permanent installations such as houses of worship, banquet facilities, night clubs, and a host of other venues, the 3000W Siena TSP118B-AN puts touring-grade sound quality into a scalable loudspeaker system that is portable and versatile.
