Turbosound Siena TSP118B-AN powered subwoofer

The Siena 3,000 Watt TSP118B-AN is a powered 18" front loaded, bass reflex subwoofer enclosure that is optimally tuned for extended low frequency response. Designed to work individually without a controller, the TSP118B-AN provides very high output FOH performance and is ideally suited for a wide range of music and live sound reinforcement applications.

Custom-Engineered Drivers

TURBOSOUND is recognised the world over for designing and building some of the most iconic loudspeakers and subwoofers. We take meticulous care and pride in maintaining that reputation by utilising only drivers designed specifically for each application – it’s what sets us apart from the competition. The TSP118B-AN features a powerful 18" low frequency driver that utilises a special inside/ outside wound voice coil for higher magnetic density, better heat dissipation, high power handling capacity, and improved efficiency. For its size and operating bandwidth, the TSP118B-AN delivers extremely high output that is virtually distortion-free – for world-class low frequency performance that will stand the test of time.

Class-D – Massive Power, Perfect Sound

Equipped with a very efficient and lightweight KLARK TEKNIK Class-D power amplifier, the TSP118B-AN provides an impressive 3,000 Watts of output power in a highly portable and lightweight package. Class-D amplification makes all the difference, offering the ultimate in energy efficiency and eliminating the need for heavy power supplies and large heat sinks.

Onboard DSP

A high degree of control over the loudspeaker system‘s performance is managed by a sophisticated, but easy to use KLARK TEKNIK Digital Signal Processor (DSP), which provides dynamic EQ and transparent limiting for the utmost punch and definition at high output levels – and long-term reliability.

Intuitive User Interface

On the rear panel 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). A combination balanced XLR/jack input is provided, plus a balanced XLR output for connecting to powered satellite loudspeakers.

ULTRANET Connectivity

The TSP118B-AN also features our 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 translate directly into significant time saved during installation. An onboard USB port provides access for remote control of the TSP118B-AN via a free PC computer software download from turbosound.com – as well as convenient DSP firmware updates.

Birch Plywood Construction

Finished in a highly durable semi matt black paint, the TSP118B-AN is constructed from 18 mm (¾ ") birch plywood and includes: a 35 mm 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.

Touring-Grade Performance

Designed to provide exceptional performance for traveling musicians, or permanent installations such as houses of worship, banquet facilities, night clubs – and a host of other venues, the 3,000-Watt Siena TSP118B-AN puts touring-grade sound quality into a scalable loudspeaker system that is supremely portable and versatile.
