The highly efficient 350W Class-D amplifier powers the 1" titanium compression driver and 8" woofer, providing crisp, detailed sound with a wide frequency range from 20 kHz down to 75 Hz.

Easy Bluetooth Connectivity
Thanks to Bluetooth connectivity, the Alto Professional TX Series ensures that users can get their PA system up and running completely cable free. This feature is perfect for any application that requires two simultaneous sources of audio, such as a microphone and background music running at the same time, a wedding MC announcing the bride and groom's first dance over music, a fitness instructor leading a spin class while energetic tunes pump in the background, a busker playing along to a backing track, etc. In addition, the TX Series' powerful Bluetooth True Wireless Stereo (TWS) connectivity allows users to run two units in conjunction with one another without having to purchase any extraneous equipment or cables.

Not only is this unit equipped with an ergonomic handle, but it's conveniently lightweight, making setup and transport easier than ever.

In addition, the back panel of the TX408 is outfitted with simple, easy-to-use parameters that give users control over EQ without weighing them down with a confusing array of knobs and sliders.

Great lil addition to small 1 speaker events !

Surprisingly loud and bassy

I bought these for a four-piece band gig at an outdoor wedding. I only needed to crank the volume halfway, providing clean sound with no clipping. The bass is surprisingly good for an 8-inch speaker, better than other 10-12 inch speakers I have tested. The speakers are so light that set up is a breeze. Highly recommend!
