Electrovoice TX 1181

A TX subwoofer designed for sound reinforcement: effective bass support without complexity

The TX1181 follows a clear logic: to provide real support in the low spectrum to a sound reinforcement front-of-house, while remaining simple to implement. In its passive version, it naturally integrates into many existing setups with external amplification, whether as a main system or as occasional reinforcement. Its omnidirectional (horizontal and vertical) dispersion is typical of a subwoofer: energy is distributed evenly throughout the room, which facilitates placement and coherence with the tops.

For whom and for what uses? An 18" subwoofer tailored for live, DJ, and event applications

The Electro-Voice TX1181 is aimed at users who want credible and physical bass without resorting to oversized solutions. It is particularly suitable for bands, DJs, event professionals, community organizations, and multipurpose venues looking for a subwoofer capable of handling high levels, with firm reproduction on the kick drum, bass, and electronic elements.

Thanks to its useful range centered on the low spectrum (50Hz - 160Hz), it is ideal for relieving the main speakers and gaining headroom on the mix. In configuration, it works equally well as reinforcement (small front-of-house) or in multiple subwoofers to extend coverage and level reserve for more ambitious events.

Performance and design: level, durability, and field-oriented manufacturing

18" EVS-18S driver: impact and control

At the heart of the TX1181, the 18" (457mm) low-frequency driver EVS-18S is designed to deliver solid bass with good mechanical resistance. This architecture provides a sense of attack and punch while keeping the lows clean when the level rises. The on-axis sensitivity of 100dB SPL contributes to better overall efficiency: more level is achieved for the same power, a direct advantage in live performance.

Acoustic pressure and frequency range: the necessary reserve for front-of-house

With a max SPL rated at 132dB SPL, the TX1181 clearly targets sound reinforcement contexts. Its frequency response of 50Hz - 160Hz focuses on the most useful zone to reinforce the low end of the mix while limiting less manageable frequencies in certain rooms. The 30Hz cutoff frequency is an important reference for filtering and managing subsonics in the signal chain, especially when optimizing the system via amplification and processing.

Touring construction: EVCoat, steel grille, and rotatable logo

In live use, durability is as important as level. The plywood & MDF enclosure with EVCoat finish helps withstand repeated handling. The black powder-coated 16GA galvanized steel grille effectively protects the driver, and the rotatable logo allows for a neat presentation depending on the subwoofer's positioning.
