FS 189 “The powerful one”

Cea mai mare incinta din seria 180 este FS 189. Are rezerve de putere incredibile, este robusta si livreaza sunet de inalt detaliu, armonios cu un bass scurt, percutant. Este la fel de impresionanta cand este folosita atat ca incinta principala in sistemele surround mari, cat si ca incinta stereo de inalta performanta, rezistenta la nivele mari de putere. Datorita unei bune eficiente, ofera o reproducere excelenta a sunetului in compania amplificatoarelor mai mici sau chiar a amplificatoarelor pe lampi.

ELAC JET III tweeter used in all 180 Series range

The ELAC JET tweeter is one of the most legendary tweeters in the hi-fi trade and has won international renown with its unusual transparent and effortless sound image.

The JET tweeter was delveloped to perfection on the basis of the famous 'Air Motion Transformer' by loudpseaker pioneer Dr Oskar Heil. Its principle: a concertinaed foil membrane is driven by a strong magnet system of neodymium rods.

This 'motor' drives the air considerably faster than the conventional pistonic technique. High sensitivity and extraordiary dynamics are the result. Due to continuous improvement, the JET III tweeter now creates an effortless and airy resonance-free image up to 50,000 Hz, and with its linear frequency response is ideally suited for the reproduction of DVD-A and SACD.

The ELAC "JET Dispersion Control DC" is a flat ring made of open-cell rubber foam which is mounted around the JET orifice with four clasps (or with adhesive tape).

The JET DC results in a broadband reduction of about 0.5 dB of the radiated sound level nearly independent of frequency. The JET DC is best suited for rooms with little sound absorption at high frequencies, especially for rooms with large windows without curtains or with a smooth floor without a carpet.

Note: The loudspeakers of the 180 series are not supplied with the JET Dispersion Control - it is an optional accessory.

Midrange Unit

MT 140 midrange used in FS 189

The midrange cone is designed in the ELAC proprietary aluminium-sandwich technique which avoids noticeable resonances in the diaphragm.The "Full-Roll" fabric surrounding expands the transmission range up to high frequencies to facilitate the crossover to the tweeter.
The spider is vented at both sides resulting in a symmetric membrane displacement which reduces distortions at low frequencies.
The magnetic system is shielded avoiding picture distortions in a CRT TV set.

Bass Unit

TT 175 midbass used in BS 184 and FS 189

The design of the woofers of the 180 series are based on the aluminium-sandwich technique. The wide rubber surrounding and the aerodynamic optimised - providing best air-flow - frame together with the spider being vented at both sides result in an extra large maximum membrane excursion.
The 31mm diameter voice coil and the powerful magnetic system increase the force factor - more efficiency - and by this the load limit is increased and consequently the deficiency rate decreased.
