79 SERIES >>2 79 SERIES Mission 7 series loudspeakers have new heights – a symbiosis of form and always been afforded the highest function building on over 30 years at respect, both in critical listening tests the forefront of acoustic design. and for their iconic style. We aim for musical perfection in The new 79 series embraces this the performance and aesthetic tradition with aplomb, elevating the perfection in design. Connect up, sit performance and design standards to down and enjoy. 3>> Development For most other manufacturers, to have revolutionary designs are control check-points at every stage loudspeaker design is full of often just assembling parts built by throughout the process. compromise.
