FS 187 Slim speaker with maximum sound
You have to hear it and touch it, because it is simply so beautiful and unostentatious. The Kiel-based company has certainly hit the bull's-eye with the distinct styling of the new 180 series. The design is simple, elegant and timeless; the speakers are utilitarian and at the same time even affordable.
This slender beauty works like her big sister, the FS 189, also using “down firing”. That means each FS 187 is equipped with 2 bass ports. One emits sound toward the back, the other downwards onto the base plate. The effect of the actual lengthening of the base port is deeper bass tuning. This arrangement also works as an acoustic low-pass filter. The rear projection bass port comes closed off with a bass control plug. By removing it, bass reproduction can be intensified. |

Treble Unit
JET III 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. |
Midbass Unit
|
TT 140 midbass used in CC 181 and FS 187
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. |
