The new top-of-the-range loudspeaker FS 609 X-PI offers state-of-the-art technology!

The FS 609 X-PI is a 4½-way floorstanding speaker, providing the unique X-JET coaxial driver with a ring-shaped midrange-tweeter driver and a new version of the legendary 4Pi tweeter, as well as new woofers with LLD technology.

The FS 609 X-PI offers both, perfect instrumental localization and superb stereophonic sound!

4Pi II Omnidirectional Tweeter Unit

360 degree omnidirectional ribbon tweeter yields a resonance-free upper cut-off frequency of 50 kHz and makes this tweeter an ideal component for the reproduction of SACD and DVD-A. Its impressive and silky sound quality gives rise to airy sound that comes off easily.

The Principle:
An 0.006mm aluminium ribbon forms the membrane, which due to its low weight shows an extroardinarily high sensitivity. When a current passes this membrane it expands and contracts like a breathing cylinder. Driven by a strong neodymium magnet system, the flexible ribbon yields maximum levels up to 50,000 Hz.

X-JET coaxial and coplanar Midrange-Treble Driver System

The new X-JET is a unique combination of a flat (aluminium honeycomb membrane) ring radiator midrange driver and a concentrically arranged JET tweeter.

By this the X-JET design realizes the vision of an acoustic point source! This facilitates an optimized acoustic power response and results in a homogeneous and very wide sound dispersion angle (s.a. the graphics below) which provides for a new kind of relaxed but very precise and detailed reproduction.

The ultra lightweight honeycomb diaphragm provides a reduced stray magnetic field combined with a strong neodymium drive. The system is driven by a 78 mm moving coil. High efficiency is achieved using coppered aluminium flat wire, edgewise-wound, on a ventilated Kapton® bobbin.

The new X-JET system yields a upper cut-off frequency of 50 kHz. This makes the loudspeaker an ideal component for the reproduction of DVD-A and SACD.

LLD Driver Technology

The new LLD driver technology (Long Linear Drive) is based on the movement of a short-wound coil (winding height: 6.5 mm) in a long air gap (height: 16 mm) with a homogeneous magnetic field. This design results in extremely linear (without distortions) movement within an amplitude of ±8 mm. The voice coil exactly mirrors the applied audio signal.
The maximum displacement is an impressive ±16 mm.

ELAC’s new woofers use high-quality titanium bobbins for greater mechanical stability. This also reduces eddy-current losses and helps achieve deeper and more precise bass reproduction.
Neodymium magnets are used to increase magnetic flux density and to save space, providing optimum magnetic field geometry and greater efficiency.
Using several small magnetic plates reduces air noise and helps to keep the temperature low even under high load.

The aluminium sandwich woofers of the FS 609 X-PI, the ELAC 330.3 JET, and of the SUB 2060 ESP use this new LLD driver technology.
