The E 30 KX is a distinctive 30 cm (12") subwoofer known for its full-screen design and high power handling capabilities. With a sensitivity of 86.5 dB (2.83V/1m), it is optimized for use in both closed volumes and Bass Reflex enclosures ranging from 28 to 35 liters. A standout feature of the E 30 KX is the use of Kevlar® membranes, which are renowned for their lightness, rigidity, and damping properties. These characteristics allow the subwoofer to produce highly dynamic bass, making every note resonate with precision and impact. The signature yellow color of the cone is emblematic of the K2 Power line, offering not just performance but an iconic aesthetic appeal.

Every component of the E 30 KX has been meticulously optimized for heightened performance. A robust and reliable rubber suspension supports the cone, featuring an exclusive profile tailored to accommodate significant travel. This ensures long-lasting durability and consistent performance even under demanding conditions. Furthermore, the aluminum chassis has received a thoughtful redesign to enhance the coil's excursion capacity, allowing for greater movement and responsiveness. The result is a subwoofer capable of delivering tight, punchy, and dynamic bass with exceptional clarity.

Though the E 30 KX is no longer available, it remains a testament to innovative engineering and high-quality acoustic performance. Its design and features reflect the dedication to excellence that characterizes the K2 Power line, making it a memorable choice for those fortunate enough to experience its exceptional sound quality.
