Trulli Audio Launches New Pro Audio Subwoofer System at NAMM

Trulli's Bass50

At The NAMM Show last week in Anaheim, Trulli Audio announced the world's first professional-grade, battery-powered subwoofer system. The Trulli Bass50 System is billed as delivering high-output bass, achieving low-end accuracy commensurate with wired systems, via an audio solution that's modular design allows it to scale from 50 to 5,000-person environments, without pulling power from the grid.

"For too long, commercial audio professionals have only been able to achieve premium sound through wired power and all the equipment, time, and labor that comes with it," says Len Foxman, founder and CEO. "The Trulli Bass50 System delivers real 'low-end bass,' can be set up in minutes, and can be optimized for nearly any environment."

The system is a one-box rig that is said to provide full-impact bass without wall power, a generator, or installation. It was designed to help audio professionals quickly deploy premium audio setups in any environment. The heart of the system is the Trulli Bass50 subwoofer, which contains an amp, DSP, battery, wireless receiver, and interface. Through the company's mobile app, users can adjust and save settings like delay and crossover, including the high-pass filter. The app also provides a series of preset audio profiles, optimized for different settings.

The system is equipped with wired and wireless connectivity options, including a 3.5mm balanced trip-ring-sleeve (TRS), USB-C digital audio input/outputs, and SKAA wireless technology. This connectivity also enables users to modularly stack systems for larger venues.

The subwoofer incorporates the features noted above, as well as a replaceable, rechargeable battery with a five-to-10-hour life at full volume, which charges from 0-100% in 2.5 hours. It also sports a tough exterior that protects against the elements. Features include Trulli Universal Port, a detachable enclosure that amplifies sound by up to ten additional dB, an M20 threaded pole mount for secure speaker placement setups, 1' and 3' poles for mounting satellite speakers, and options that connect it with nearly any top speaker, including Bose Pro, QSC, Electro-Voice, PK Sound, and more.

The company states, "As a holistic commercial system in one package, the Trulli Bass50 System reduces the need for labor-heavy equipment and wires that can create tripping hazards or need to be hidden."

The subwoofers rely on the company's patented, award-winning ThinDriver Technology, which reportedly delivers more power at a fraction of the size (and air volume) compared to conventional speakers. The TD10S driver in the system can handle 600W of continuous power, peaking at just over 1,000W, and delivers up to 122dB (131dB with the Trulli Universal Port). It has a frequency range from 20Hz to 225Hz (30Hz to 80Hz with the Trulli Universal Port).

The company has a suite of subwoofer drivers featuring ThinDriver Technology. The portfolio includes:

*TD19S 2000W and TD19S 5000W: 19" subwoofer drivers with 4" mounting depth that can handle 2,000W of continuous power, and 6" mounting depth that can handle of continuous power 5,000W, respectively.

*TD10S: A 10" subwoofer driver with a 2.7" mounting depth that can handle 600W of continuous power.

*TD6.5S: A 6.5" subwoofer driver, with a 2.2" mounting depth, that can handle 300W of continuous power.

Trulli Audio is an independent audio company based in Mundelein, Illinois. Founded by Len Foxman in 2016, The company was born from his lifelong love of jazz, matched with his extensive engineering credentials as long-time leader and president of Eagle Test Systems, which was acquired by Teradyne in 2008. Trulli's mission, the company says, "is to help music lovers fully experience the music they love without compromise, anywhere and everywhere they want superior sound."
