DALI OBERON 7

DALI’s Oberon 7 gains its model name because it uses a pair of bass drivers each of which the company rates with a diameter of seven inches (178mm). The odd diameter comes about because DALI is one of the few manufacturers that builds its own drivers and it wanted to create a driver with a larger surface area than the standard 165mm (6½ inch) driver that most other speaker designers are using. “DALI’s 178mm driver’s cone is 15 per cent larger in dimension than those drivers and the resulting larger cone area allows a lower voice coil excursion at the same sound pressure level, as well as a higher maximum sound pressure level, which leads to an effortless reproduction of the dynamics in the music,” said Andrew Richter of Amber Technology, which distributes DALI in Australia. The drivers’ performance is further enhanced though the use of DALI’s patented SMC magnetic technology which greatly reduces mechanical distortion caused by hysteresis and eddy currents. These combined improvements in the magnet motor system result in a reduction of third order harmonic distortion which in turn enables a relaxed midrange sound and a surprising amount of detailing for the class.

The motor system of the 178mm driver comprises a large ferrite magnet that surrounds a pole-piece made with a unique combination of hard magnetic iron and DALI’S soft magnetic compound (SMC). The iron ferrite forms the lower base of the pole cylinder, which is topped with a 10mm SMC disk. This combination equalises the flux field by placing the SMC disk right in the main working area of the four-layer voice coil so the coil sees a more constant flux field as it moves backwards and forwards.

“Basically, with the Oberon loudspeaker series, this famous Danish manufacturer has picked the best elements from its current speakers and brought them together in a series that delivers on audio quality, looks and versatility,” said Richter. “When the driver technologies are incorporated into a large but elegant cabinet, as they are in the Oberon 7, the combination delivers the very best in deep bass and large room performance so it’s perfect for almost any audio setup and any music or movie style.”

Available now, the DALI Oberon 7s sell for $1,999 per pair (RRP) and are available now.
