HIGHLIGHTS
High-end high-efciency three-way oor-standing
loudspeakers
• Very large three-way system with particularly high
efciency for outstanding dynamics
• Can be combined optimally with transistor and tube
ampliers from 20 watts per channel
• Attractive at-design enclosure, oating appearance
through all-metal design foot construction
Drivers
• High-power tweeter with particularly high efciency through
the 28 mm silk compound cone, solid aluminium front
panel with high-efciency wave-control horn geometry and
powerful triple magnet system
• Especially efciency and gentle roll-off-optimized midrange
with Kraft paper cone, lightweight dust-protection cone,
hard suspension, very powerful drive, extremely low-loss
silk surround and highly durable voice coil in a stable die-
cast aluminium cage. Kapton voice-coil and impedance
compensation for extremely low mechanical and electrical
loss
• High-performance woofer with high-capacity 75 mm
4-layer voice coil and lightweight air-dried Ripple cone
in a very stable die-cast aluminium cage. Kapton voice
coil, ventilated pole core, low-loss rubber surround and
extremely powerful 170 mm magnet system for minimum
loss and excellent dynamics
• Woofer and midrange: Magnet systems linearized with the
high-tech Klippel® measuring system for ideal symmetry
and minimal distortions
Cabinet
• Stylish semi-matt lacquer nish with contrasting double
stripes on the front
• Solidly built, multiple strutted MDF at enclosure with
attractive curves
• Specially designed all-metal foot construction for an
absolutely stable base
• Floor-protecting rubber feet and all-metal spikes included
• Triple bass-reex design with bi-directional airow-
optimized rounded downre tubes for maximum bass
performance
Crossover
• Elaborate, phase-optimized crossover with high-quality
tight-tolerance components
• Linearized impedance curve with very little uctuation for
optimum behavior on tube and transistor ampliers from
20 watts per channel
• High-quality all-metal connector terminal with stable, gold-
plated high-end screw terminals
