Electro-Voice TX1152FM - 15" Passive Stage Monitor (90° × 50°, 500 W continuous)

Electro-Voice TX1152FM - 15" Passive Stage Monitor (90° × 50°, 500 W continuous)

The Electro-Voice TX1152FM is a 2-way passive floor monitor designed to deliver high SPL, vocal clarity, and punch on small to medium-sized stages. Its architecture employs a 15" SMX2151 woofer and a 1.25" DH3 compression driver (titanium diaphragm) loaded into a 90° × 50° constant directivity horn , achieving a usable response of 45 Hz – 20 kHz (-10 dB) and 65 Hz – 20 kHz (-3 dB) . With 100 dB of sensitivity and up to 133 dB SPL (calculated) , it keeps your mix defined even at demanding levels.

The wedge-shaped enclosure combines plywood and MDF with EVCoat coating to withstand intensive use, and integrates two handles for secure transport. The SST (Signal Synchronized Transducers) topology physically aligns the LF and HF to reduce phase distortion and improve intelligibility. A passive crossover (≈ 1.75 kHz ) with HF protection optimizes performance across the entire bandwidth. Connectivity is provided by two Neutrik Speakon NL4 connectors in parallel (link), facilitating daisy-chain wiring.

Main features

• High output and clarity : 100 dB (1 W/1 m) and 133 dB SPL max. calculated.
• High performance transducers : SMX2151 (15") + DH3 (1.25") in 90° × 50° horn.
• Verified working range : 45–20 kHz (-10 dB) / 65–20 kHz (-3 dB) ; Recommended HPF 45 Hz .
• Admissible power : 500 W continuous / 1000 W program / 2000 W peak at 8 Ω (min. 6.2 Ω ).
• Robust enclosure : combination of MDF + plywood with EVCoat , 16 GA steel grille and two handles .
• Professional connectivity : 2 × NL4 in parallel for input/link.
• Dimensions and weight : 475 × 439 × 655 mm ; 23.5 kg .

Product benefits

• Superior intelligibility of voices and instruments thanks to the 90° × 50° waveguide and SST alignment.
• Reliability on tour thanks to its mixed wood construction and durable EVCoat finish.
• Easy integration into riders : 8 Ω impedance, NL4 in parallel and standard power of the category.
• Portability : Wedge format with two handles for quick backline changes.

Use cases

• Stage monitoring for lead vocals, keyboards, guitars and brass.
• Rental and backline for small/medium-sized stages requiring high SPL and endurance.
• Mobile installations (theaters, cultural centers) with versatile monitor configurations.

Frequently Asked Questions

• Can I link multiple wedges? Yes, the two NL4s are in parallel for quick linking .
• What high-pass filter is recommended? 45 Hz (24 dB/oct) to protect the LF and increase headroom.
• What is the crossover frequency? Approximately 1.75 kHz on the integrated passive crossover.
