Alto Professional TX 415 Active Loudspeaker

Alto Professional TX415 — 700W Active 15" PA Loudspeaker

The Alto Professional TX415 is the flagship of the TX Series, a 700W Class-D powered loudspeaker designed and tuned in the United States for venues where clarity and volume both matter. Inside the trapezoidal cabinet, a 15" woofer pairs with a 1" titanium diaphragm HF compression driver to project full-range sound into large rooms and outdoor event spaces. Output hits 121 dB peak SPL across a 75 Hz to 20 kHz frequency range, so vocals stay intelligible and bass lines stay present at high volume. Whether on a pole as a main or angled back as a floor wedge, this cabinet handles working presenters, bands, and mobile DJs.

Standout Features of the TX415

Bluetooth 5.0 with True Wireless Stereo (TWS) linking sets the TX415 apart from typical powered cabinets — two units can be paired wirelessly for a cable-free stereo rig, which is rare at this tier. The built-in 2-channel mixer accepts microphone, line-level, and Bluetooth inputs simultaneously, so an MC can run over a backing track without extra gear. A full metal grille and polypropylene enclosure protect the drivers during transport, while the 36 mm pole socket and monitor angle configurations let the same box serve as mains or wedge.

Key Specifications for Live Sound Users

The 700W Class-D amplifier splits 500W to the low-frequency driver and 200W to the high-frequency compression driver, giving each transducer dedicated headroom. The 90° x 60° wide-dispersion horn keeps coverage even across the audience area, and output limiter plus thermal protection circuits guard against clipping during long sets.

• Frequency Range: 75 Hz – 20 kHz — full-range response from kick drums to vocal highs.
• Maximum SPL: 121 dB peak — enough volume for houses of worship, conference centers, outdoor stages, and rehearsal rooms where the speaker has to cut through crowd and background noise.
• LF Driver: 15" woofer with 2" voice coil — moves serious air for punchy low end.
• HF Driver: 1" titanium diaphragm compression driver — handles vocals and cymbals without harshness.
• Inputs: Combo XLR-1/4" mic/line + Bluetooth — covers mic, instrument, and wireless streaming in one box.
• Pole Mount: 36 mm socket — fits standard speaker stands.

Who the Alto TX415 Suits

The Alto Professional TX415 is the right choice for working musicians, mobile DJs, fitness instructors, and event A/V providers who need a single powered speaker for small-to-medium venues without a rack of outboard gear. Solo performers can run a mic and a Bluetooth backing track through the built-in mixer, while bands can pair two cabinets wirelessly via TWS for stereo coverage at larger gigs. Houses of worship, conference centers, and rehearsal spaces benefit from the 121 dB output and the simple rear-panel controls that keep operation accessible to non-technical volunteers. At 14.4 kg with top and side carry handles, it stays portable enough for one-person load-in.
