Test reviews

What do trade magazines say about this product?

Absorbers or metal spikes - you decide!

All floor-standing speakers in the range can be set up with the support of resonance absorbers or, alternatively, metal spikes supplied additionally.

Gold-plated bi-wiring terminal

The loudspeaker cables are connected to the terminal with encapsulated clamps, providing secure contact even for larger gauge cables. Bi-amping and bi-wiring are also possible.

Bass/mid-range drivers in detail

The baskets of the 170 mm bass/mid-range drivers are made of torsion-resistant die-cast aluminium. Together with the aluminium-ceramic membranes, these chassis guarantee particularly high impulse fidelity and clean bass reproduction.

The noble art of precision

A high-efficiency Magnat Fmax tweeter consisting of a dual-compound fabric membrane operates in the treble range. A dampened pole piece hole produces a particularly harmonious transition to the mid-tone range.
