Jammin One is LEM Commercial's column PA system + sub designed to deliver high performance in an easily portable package.

The dual stacked full-range column features a total of 12 drivers (6 + 6) 3" drivers with 25 mm voice coils, featuring high sensitivity and a controlled dispersion pattern of 30° vertically and 120° horizontally, ideal for ensuring vocal intelligibility and sound reproduction even in complex environments.

The 12" active subwoofer with a 65 mm voice coil provides an extended response down to 30 Hz, with 600 W of power and a high sound pressure level, while maintaining precise control over low frequencies. The entire system delivers a total power of 300 W for the column and 600 W for the sub, offering performance suitable for live events, DJ sets, conferences, and mobile installations.

The DSP section integrates advanced features such as an 8-band parametric equalizer, configurable crossovers (with Butterworth, Bessel, and Linkwitz-Riley filters), adjustable limiter and compression, input and output delay, and an LCD display. Connectivity includes XLR inputs and outputs and RS485 ports for control.

With its rugged construction, modularity, and high-quality sound, Jammin One is a complete solution for those who need a powerful, versatile, and easy-to-configure system.
