The goal was to incorporate all design know-how into the development of the Lagrange 98. This loudspeaker had to feature phase-correct sound radiation, absolute adherence to detail, a linear frequency response, outstanding cone outwards movement and the best available components. We chose the magnetically shielded version of the Scan-Speak D2904/9800 and for bass the Alcone AC 5.25, a driver with a rigid cone, yet a good cone outwards motion. The Seas Excel W15 CY 001 was also a contender, however, this driver doesn't allow a 6dB separation on the crossover due to the more pronounced resonance.
Considering the above mentioned characteristics the Lagrange 98 comes close to the ideal solution regarding development and lab results. Therefore the Langrange 98 is - besides the Angara 2 - one of the speakers most consequently developed towards High-End.
The Alcone Lagrange 98 is available as satellite or floorstanding version. right: frequency response of the Lagrange 98
The Lagrange 98 (sat) features the following characteristics: - cones with ideal stiffness, - the shows hardly any unwanted resonance - accurate sound projection by correctly timed crossover - ScanSpeak D2904/9800 a tweeter with high-end qualities - an absolute flat frequency response (+/- 1 dB), - only a small dip at 500 Hz, compensated by placing the speakers close to rear or side walls - universal deployment, since D2904/9800 07 is magnetically shielded - picture of double magnet to the right.
