ToneWinner SW-D4000 800W 12" Subwoofer

Finesse to Impress

Equipped with a built-in 800-watt RMS amplifier and a robust 12" driver, the SW-D4000 delivers consistent, punchy bass all the way down to 20Hz and beyond. With its exceptional power and clarity, this subwoofer provides a deep and impactful bass response that adds a new dimension to your movies, music, and games.

However, the SW-D4000 is more than just raw power. It's designed to impress both visually and acoustically, as well as continue to impress even after countless intensive listening sessions. Presented in a sleek black ash finish and a protective mesh grill, the SW-D4000 seamlessly integrates into any home theatre or audio setup, professional or casual. The sturdy MDF cabinet, along with two carefully designed ports, optimizes airflow and reduces unwanted resonances, resulting in a clean and distortion-free bass performance.

Precise Control

There's no doubt that the Tonewinner SW-D4000 has plenty of power to offer, but for it to easily integrate into music and home theatre systems, it needs to also offer versatility and convenience. With either the LCD touch controls on the back of the unit, or with built-in Bluetooth connectivity, you can effortlessly control the subwoofer settings using your smartphone through the Tonewinner subwoofer app. Adjust the gain, phase, and listening mode, or apply a personalized parametric equalizer (PEQ) - all from your listening position.

Plays Nicely With Any System

On the rear panel, you'll find a versatile range of connections that allow the SW-D4000 to play nicely with most amplifiers and processors. In addition to the individual Line-In and LFE inputs, which will support a single-ended or Y-split cable from a preamp or integrated stereo/surround amplifier, the subwoofer will also accept a balanced XLR LFE connection, typically found on advanced preamp processors.

In cases where your amp has only a single subwoofer output, but you want to run two subwoofers or more in a single system, you can daisy chain multiple SW-D4000 units together for perfectly synchronised, evenly spread bass in larger rooms.
