Eminence Speaker Europe is using PLASA 2001 as the platform to introduce its new sub-bass and bass driver range, Eminence Magnum. Power ratings are expected to be in the region of 1kW. The Magnum is available in 15" and 18" sizes and uses a ‘bullet-shaped’ aluminium phaser at its centre to act as an acoustic device that minimises destructive phase conditions. The phaser doubles as a heatsink. Motor heat is drawn through the aluminium by the draught from cone movement (a principle employed by the company’s Kilomax series).Magnum possesses a number of other interesting developments including a copper shorting ring to reduce distortion; core periphery ventilation - a series of eight holes in the pole piece that enable a continuous exchange of hot air inside the motor and cooler air inside the enclosure; sinusoid suspensions; lower QT parameters for use in smaller vented enclosures; a choice of HO and LF specifications. The HO version has a lighter moving mass for greater sensitivity; LF has a longer X-MAX and greater moving mass for extended low frequency performance.
The Eminence stand at PLASA will be the biggest ever taken by the company. Managing director Arthur Barnes explains: "We have seen a growth in the importance of this exhibition and an increase in the attendance of key buyers - many are people we perhaps do not reach at Frankfurt. PLASA, in reaching a different audience, has become almost as important to Eminence as Frankfurt."
Eminence can be found on stand E24.
