Alto Professional TX 408 Active Loudspeaker

Alto Professional TX408 — Compact 350W Powered PA Loudspeaker

The Alto Professional TX408 is a portable 8-inch powered loudspeaker engineered for small- to mid-sized venues, mobile gigs, and on-stage monitoring. With 350W of Class-D power and a built-in two-channel mixer, this model delivers clear, robust sound that punches well above its price point. The TX408 is the right choice for working musicians, presenters, and DJs who need a lightweight, road-ready speaker that can be set up in seconds and trusted to fill a room.

What Sets the TX408 Apart

Bluetooth True Wireless Stereo (TWS) linking lets two TX408 cabinets run as a stereo pair without a single cable between them, while the integrated two-channel mixer accepts a microphone, a line-level source, and a Bluetooth stream simultaneously. A full-metal grille, polypropylene enclosure, and ergonomic top handle keep the unit protected during transport and gig-to-gig load-outs.

Power and Amplification — Class-D Efficiency for Small Gigs

The Class-D amplifier stage is split between the low-frequency and high-frequency drivers, giving the cabinet real headroom for vocals, music playback, and instrument reinforcement without running hot. At this tier, that efficiency translates directly into a lighter box that is easier to carry from the car to the stage.

• Total Output Power: 350 W — split 250 W LF + 100 W HF
• Amplifier Class: Class-D — ultra-efficient, low-heat operation
• Maximum SPL: 114 dB peak — enough volume for rooms up to roughly 100 people

Drivers and Coverage — Full-Range Sound From an 8-Inch Box

An 8-inch woofer with a 1.4-inch voice coil handles the low end down to 75 Hz, while a 1-inch titanium diaphragm compression driver carries the highs cleanly up to 20 kHz. The wide-dispersion horn is shaped so a single cabinet covers a small audience evenly, reducing the need for delay speakers.

• LF Driver: 8-inch (203 mm) woofer with 1.4-inch (35.5 mm) voice coil
• HF Driver: 1-inch (25.4 mm) titanium diaphragm compression driver
• Frequency Range: 75 Hz to 20 kHz (-3 dB)
• Coverage Angle: 90° H x 60° V — wide-dispersion horn

Connectivity and Physical Design — Built for Working Players

The rear panel keeps controls simple: one combo XLR-1/4" mic/line input, an XLR link output for daisy-chaining additional cabinets, a Contour EQ switch for music playback, and Bluetooth pairing. A standard 36 mm pole socket and built-in monitor angle let the same cabinet work as a main on a stand or as a floor wedge.

• Inputs: 1x Combo XLR-1/4" TRS mic/line + Bluetooth 5.0 streaming
• Output: 1x XLR 3-pin link output for chaining multiple speakers
• Wireless: Bluetooth 5.0 with TWS stereo linking
• Weight: 5.9 kg — easy single-hand carry via top handle
• Construction: Polypropylene enclosure with full-metal grille

Who the Alto Professional TX408 Is For

The TX408 is the right choice for mobile entertainers, solo musicians, fitness instructors, wedding DJs, and presenters who run small- to mid-sized events and need a single cabinet that can do mains duty or double as a stage wedge. It suits anyone who values quick Bluetooth setup, light carry weight, and the flexibility to link a second unit wirelessly for wider coverage in rooms of roughly 50 to 200 people.
