Alto TS412 12-Inch Powered Loudspeaker

The Alto TS412 is a 12-inch powered loudspeaker built for performers, DJs, and venues needing pro-grade sound with wireless convenience. It delivers 2500W peak power through a Class D amplifier driving a 2-way system. A 2.5-inch voice coil woofer and 1-inch ceramic compression driver produce clear, deep audio with minimal distortion at high volumes.

132dB SPL Output and Class D Efficiency

The speaker reaches 132dB SPL peak output, providing substantial headroom for medium to large events. The Class D amplifier topology ensures efficient power delivery while keeping the unit weight to 33.0700 units for portable use. Onboard DSP manages crossover and protection, maintaining consistent performance across dynamic live sound applications.

Bluetooth 5.0 App Control and Wireless Linking

Bluetooth 5.0 enables audio streaming and True Wireless Stereo linking with another TS4 unit without cables. The free Alto App for iOS and Android provides remote configuration and control over four Speaker Use modes including Custom EQ. A 3-channel mixer with two combo XLR/TRS inputs handles mics, instruments, or line-level sources alongside wireless playback.

Questions about this item

How do I mount the Alto TS412 on a speaker stand and what step is often missed?

Align the integrated pole-mount socket with the stand, lower the cabinet fully, then engage the locking mechanism so the speaker cannot rotate or lift off.

What component will need attention after extended high-SPL use?

The 1-inch ceramic compression driver diaphragm can fatigue over time; inspect for reduced high-frequency output and replace the diaphragm assembly if clarity drops.

At what output level does the 2500W amplifier begin limiting to protect itself?

The onboard DSP engages peak limiting when the signal approaches 132 dB SPL, reducing gain to prevent clipping and thermal overload.
