Alto Professional TS412 2500 Watt 12-Inch 2-Way Powered Loudspeaker
Prepare to command every room, mesmerize every crowd, and deliver performances that echo in people's memories long after the last note fades. The Alto Professional TS412 is engineered to transform ordinary gigs into extraordinary experiences. With 2500 watts of pure power coursing through its veins and smart Bluetooth technology at your fingertips, this powerhouse proves that big sound doesn't have to come in a back-breaking package.
The TS412 brings professional-grade performance in a surprisingly portable package that'll have you wondering how you ever managed without it.
Smart Technology That Works as Hard as You Do
The TS412 doesn't just play loud — it plays smart, giving you complete control over your sound without the complexity that usually comes with professional equipment.
FREE Alto App Control: Your smartphone becomes a powerful remote control center, letting you adjust Bluetooth levels, tweak custom EQ settings, and configure speaker modes from anywhere in the venue. No more sprinting back to the speaker between songs to make adjustments — now you can fine-tune your sound from the sweet spot in the room.
True Wireless Stereo Linking: Pair two TS412 speakers via Bluetooth for pristine stereo separation without running a single cable between them. It's like having a wireless sound engineer working behind the scenes, ensuring your audience gets the full sonic experience.
Built-in 3-Channel Mixer: Plug microphones, instruments, and line sources directly into the rear panel without external mixers or confusing adapter chains. The dual XLR/TRS combo inputs handle everything from delicate acoustic guitars to booming bass lines, while the dedicated Bluetooth channel keeps your backing tracks flowing seamlessly.
Performance That Delivers When It Matters Most
When the spotlight hits and the crowd's energy peaks, the TS412 rises to the occasion with rock-solid reliability and room-filling power that never quits.
2500W Peak Power Output: The combination of a 12-inch high-temperature voice coil woofer and 1-inch ceramic compression driver creates a sonic landscape that's both thunderously powerful and crystal clear. Your low-end punches through the mix while vocals cut through even the chattiest crowds.
Fanless Class D Amplifiers: Advanced cooling design means your speaker runs whisper-quiet and ultra-reliable, even during those marathon four-hour sets.
4 DSP Speaker Modes: Whether you're setting up for an acoustic duo or preparing for a full rock show, simply press a button to optimize the speaker's response for your specific application. The custom EQ mode via the Alto App lets you save your signature sound settings for instant recall at every gig.
Built for the Road, Designed to Impress
Professional performance shouldn't come at the expense of your back or your venue's aesthetic — the TS412 proves you can have power, portability, and style in one sleek package.
Lightweight Yet Durable Construction: At a fraction of the weight you'd expect from a speaker this powerful, the TS412 makes load-in and setup a breeze. The rugged enclosure shrugs off the bumps and knocks of regular transport while maintaining its professional appearance gig after gig.
Versatile Mounting Options: Pole-mount it for maximum coverage, angle it as a wedge monitor for on-stage clarity, or suspend it from the integrated M10 points for permanent installations. One speaker, endless possibilities — adapting to your venue instead of forcing your venue to adapt to it.
Sleek Professional Aesthetics: The clean, modern design fits seamlessly into any environment, from intimate coffee shops to corporate events. Your gear should enhance your professional image, not detract from it, and the TS412's understated elegance ensures all attention stays focused on your performance.
The Bottom Line: Your Sound, Elevated
The Alto Professional TS412 represents everything modern performers demand from their sound reinforcement: massive power in a manageable package, intelligent features that simplify rather than complicate, and the reliability to handle whatever your musical journey throws at it. This isn't just an upgrade to your current setup — it's a transformation of your entire approach to live sound.
