High-end 4-way floorstanding speaker

The 707 is the top-of-the-range model in the Signature 700 series. Standing a good meter in height, it houses a dual tweeter module, a 170 mm midrange driver and two 170 mm woofers, making it a true 4-way system. It delves deeply into the lowest ranges, with the lower cut-off frequency occurring at an impressive 22 Hz. Height-adjustable solid metal spikes ensure a secure footing and acoustic decoupling. The sturdy connection terminal allows bi-wiring and/or bi-amping configurations. The elaborately designed crossover with its 24 dB filters is both amplitude- and phase-optimized.

Ceramic/aluminum cone

Ceramic/aluminum cone for woofer and midrange drivers, non-magnetic die-cast aluminum baskets with voice coil ventilation

HiRes dual tweeter system for maximum resolution and transparency

Signature 707 Terminal

Multi-braced MDF cabinet, amplitude- and phase-optimized crossover, bi-wiring/bi-amping terminals with screw terminals
