Louder. Clearer. Smarter!

Where the TS3 series exceeded expectations, the TS4 completely redefines them. The TS4 series builds on the legacy of the best-selling TrueSonic speakers, delivering more power, clearer sound, and enhanced Bluetooth® features like 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 a 10" woofer and a 1.4" compression driver, the TS410 offers 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, provides convenient remote control of Bluetooth® levels, speaker usage modes, custom EQ, and sub size selection. Additionally, the True Wireless Stereo connection can be configured via the app to save setup time.

Built-in 3-Channel Mixer

Each TS4 features an integrated 3-channel mixer with two mic/line input channels and a dedicated Bluetooth® channel. The mic/line channels have XLR/TRS combo jacks and can handle microphones, instruments, and line-level signals without extra hardware or settings. Just plug in at the rear and start playing.

Easy Bluetooth® Streaming and Speaker Linking

The TS4 is the ideal high-power streaming solution. Thanks to built-in Bluetooth® connectivity, you can easily pair your laptop, phone, or tablet and enjoy music in no time. With True Wireless Stereo, Bluetooth® audio signals can be transmitted in perfect stereo to two TS4 speakers without cables.

DSP Modes for Optimal Sound in Any Setting

With three preset "Speaker Use" modes, you can optimize the speaker for any application, ensuring great sound at the push of a button. For even more control over your sound, you can configure a custom EQ in the Alto app and remotely adjust settings from anywhere in the venue. You can even save 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 designed for maximum reliability, whether for mobile gigs, performances, or permanent installations. Each speaker features a lightweight, sleek black-box design that can be used freestanding, as a wedge monitor, on a stand, or flown using the integrated mounting points.

Level up your live sound!
