Three way stand-mounted loudspeakers

The Jensen LS-4B are 3-way speakers designed to offer detailed and balanced sound reproduction, perfect for medium-sized listening environments. Their robust design and attention to materials make them suitable for both critical listening and everyday entertainment. The design philosophy behind these speakers focuses on using high-quality components to ensure natural, uncolored sound.

The 12-inch (25 cm) woofer is the heart of these speakers, designed to reproduce deep and precise bass. The diaphragm is made with high-performance materials that minimize distortion and enhance low-frequency response, resulting in rich, dynamic sound. The 6-inch (15 cm) midrange driver is responsible for accurately reproducing midrange frequencies, delivering vocals and acoustic instruments with a natural tone. This driver features an advanced material voice coil to reduce non-linearities and distortion. Finally, the 1-inch (2.5 cm) tweeter is constructed with an aluminum diaphragm, designed for clear and precise reproduction of high frequencies, ensuring bright highs without being intrusive.

The 3-way crossover is engineered with great precision to ensure smooth transitions between the drivers, with optimized crossover frequencies at 500Hz for the woofer-to-midrange transition and at 3kHz for the midrange-to-tweeter transition. The crossover is built with carefully selected components to minimize distortion and improve response consistency.

The cabinet structure is internally reinforced, which helps reduce unwanted resonances and improves sound quality. Additionally, the optimized driver arrangement contributes to even sound dispersion, providing greater stereo imaging stability even in larger listening environments.
