The compact MDF enclosure with reinforced side walls and a 25 mm thick MDF base plate ensures stable retention of the woofer. Inside the bass box, there is a powerful EMPHASER 20 cm / 8-inch woofer that delivers strong performance. For the best possible bass output, the woofer is mounted according to the downfire principle. The bass driver is equipped with an extremely sturdy 3-layer sandwich fiberglass cone with a Nomex core, while the TSV 2 x 2 ohm voice coils are heat-resistant. It also features Nomex dual-centering spiders, a strong dual magnet, and vented pole plates. The tuning of the EBR-M8DX is designed to produce extremely deep bass. The sound aims for a rich bass that harmoniously integrates into the audio system. The subwoofer features a rear wall tilt that saves space and practical push terminals for easy installation and removal.
