What is it?A range of active speaker enclosures powered by Class-D amplifiers. DetailsThe D Line range currently comprises four models: the HD10-A and HD22-A active 2-way monitors, the HDL20-A active line array module and the HDL18-S high-powered sub-woofer. The onboard Class-D power amplifier technology is said to deliver “ultra-fast attack, realistic transient response and impressive audio performance” while the integrated DSP provides control over crossover, eq, soft limiting, compression and dynamic bass boost functions. All transducers used in the range incorporate Neodymium magnets for reduced weight and higher efficiency. The newly-designed 1” and 2” compression drivers are fitted with pure titanium domes and are said to provide a “transparent mid-range” plus enhanced high-frequency reproduction with large, constant-directivity horns offering more precise directivity. D Line enclosures are moulded from a composite polypropylene material said to dampen vibrations even at high output volume settings and fitted with ergonomically-designed aluminium handles with internal rubber handgrips for improved portability.
