The L-4 is a high-performance, highly sensitive, lightweight, multi-purpose, and exceptionally compact design—the latest innovation from Real Sound in the field of portable line-array technology. It seamlessly integrates the proven advantages of Real Sound’s traditional line-source technology with a plug-and-play approach, a sleek aesthetic, and exceptional sound immersion, clarity, and tonal balance, all delivered by a pair of 9-inch × 3.5-inch neodymium bass drivers and a pair of 3-inch × 1-inch neodymium tweeters.
The L-4 features a pair of 9-inch neodymium bass drivers and three 1-inch neodymium tweeters, delivering a flat and wide frequency response. Thanks to a carefully engineered cabinet design, the low-frequency extension reaches as low as 140 Hz, while the high-frequency upper limit extends to 18 kHz. Paired with the manufacturer’s pre-configured L-4 DSP firmware, the L-4 offers an exceptional listening experience, with clear, transparent vocals and exquisitely detailed high frequencies.
The L-4 features a direct-radiation design without a waveguide, delivering exceptionally natural sound with a wide coverage pattern. Its high-sensitivity transducer ensures effortless, intuitive operation. The L-4’s outstanding projection and ultra-wide polar pattern provide uniform sound pressure levels across expansive areas, making it ideally suited for flat, open auditoriums.
The L-212B is a high-performance, high-power, multi-purpose speaker with an exceptionally compact cabinet design, equipped with two 12-inch (65 mm voice coil) high-quality subwoofers. Its stylish, plug-and-play configuration delivers powerful presence, outstanding clarity, and excellent tonal balance.
The L-212B’s low-frequency performance is delivered by a high-efficiency neodymium–iron–boron driver unit, paired with an optimally tuned bass-reflex port and advanced internal design features that effectively suppress standing waves and unwanted resonances. The bass-reflex port has been meticulously optimized to minimize port noise and compression, resulting in impressive low-frequency extension and output capability.
