The DAD™ 28 XTR-04 “Arrow point” tweeter is the definitive union between the timbre of classic drivers with dome diaphragms, and the great features of a ring tweeter. This tweeter is also configured with a double rear acoustic labyrinth decompression chamber made with resonance free solid spruce wood.

Lilium is a loudspeaker system made up by two separate tuned enclosure, all totally independent from each other. The main full-range enclosure benefits from the use of the para-aperiodic Stealth reflex™ tuning system. The infra-low frequencies reproduction enclosure is implemented with our patented decoupling system Zero Vibration Transmission™, with the removal residual vibration system Tuned Mass Damper™ and with an up firing passive radiator.

The infra-woofer's cabinet is mechanically decoupled from the rest of Lilium’s structure and, consequently, from the floor through the patented system Zero Vibration Transmission™. This system, optimized with progressively yielding elastomers, not only totally reduces the transmission of spurious vibrations into the listening environment, but it also inhibits any modulation between the infra-woofers and the frontal drivers, at the same time allowing the infra-woofers to function in “ground-effect”.
