Louder. Clearer. Smarter!

Where the TS3 series exceeded expectations, the TS4 redefines them entirely. The TS4 series builds on the legacy of the best-selling TrueSonic speakers and delivers more power, clearer sound and extended Bluetooth® features such as streaming, speaker linking and app control. The new TS4 series is compact, lightweight and designed for reliability, making it easy to deliver great live sound at any event.

True Sonic Power

Whether you need powerful vocal reinforcement or club-shaking bass for a DJ set, the TS4 speakers deliver loud, clear, room-filling sound for any application. With an 8" woofer and a 1.4" compression driver, the TS408 provides class-leading power and clarity with 2000 watts.

Free Alto App for Remote Setup and Control

The free Alto App, available for both Android and iOS, gives you convenient remote control over Bluetooth® levels, speaker-use modes, the custom EQ and Sub Size selection. You can also configure the True Wireless Stereo connection via the app to save setup time.

Built-in 3-Channel Mixer

Each TS4 features an integrated 3-channel mixer with two mic/line channels and a dedicated Bluetooth® channel. The mic/line channels use XLR/TRS combo jacks and accept microphones, instruments and line-level signals without extra hardware or settings. Just plug them into the rear and you're ready to go.

Simple Bluetooth® Streaming and Speaker Linking

The TS4 is the ideal high-power streaming solution. Built-in Bluetooth® connectivity makes it easy to pair your laptop, phone or tablet and start playing music instantly. The True Wireless Stereo feature lets you send Bluetooth® audio in perfect stereo to two TS4 speakers without cables.

DSP Modes for the Best Sound in Any Application

The TS4's three preset "Speaker Use" modes let you optimize the speaker for any scenario so you get great sound at the press of a button. For even more control, configure a custom EQ in the Alto App and adjust settings remotely from anywhere in the venue. You can even store your preferred custom EQ directly on the TS4 for quick recall.

Versatile and Reliable

From premium drivers to fanless Class-D amplifiers, every aspect of the TS4 series is built for maximum reliability—whether you're doing mobile gigs, performances or fixed installations. Each speaker features a lightweight, sleek black-box design that works freestanding, as a wedge monitor, on a pole or flown using the integrated M6 rigging points.

Level up your live sound!
