13 cm (5") low-midrange driver with Polypropylen membran, neodymium magnet and rubber surround which is suited well for uses where very low installation depth and low weight is required but good sound cannot be renounced in the bass and midrange tone area. The basket front has an integrated fabric grille, which makes a real grille unnecessary and protects at the same time the usually bare airgap, as well as the voice coil.

10 cm (4") high-end full-range loudspeaker with excellent balanced response characteristics and slightly increasing high-range for a pleasant sound even outside of 0-axis. High efficiency with low distortion are just some of the qualities of this speaker.

6.5 cm (2.5") fullrange speaker with balanced frequency response and very good highs. Especially suitable as built-in speaker for music reproduction and as driver for 100 V network column speakers. Outstandingly high efficiency compared to the small size. Equivalent to model FRS 7 - 8 Ohm, but with connectors 2.8 x 0.8 mm (+) and 2.8 x 0.8 mm (-).

5 x 9 cm (2" x 3.5") full-range speaker with wooden cone and stable plastic basket. Flat and lightweight design because of neodymium. The cooperation of the seperate components leads to a very linear frequency response up to deepest frequencies by way of comparison, so that the loudspeaker can be also used in miniature hi-fi speakers.

*) IP protection class for front side when built into a sealed enclosure

10 cm (4") fullrange speaker with high efficiency and balanced frequency response. Especially suitable as control speaker for electronic devices. Equivalent to model R 10 S - 4 Ohm, but with connectors 4.8 x 0.8 mm (+) and 2.8 x 0.8 mm (-).

Waterproof 8 cm (3.3") fullrange speaker with a transparent plastic cone and rubber sealing ring. Very high mean sound pressure level. Optimised for voice and signal output.

*) IP protection class for front side when built into a sealed enclosure (gluing of the loudspeaker might be necessary)

**) 1 m height of water, 16 h

17 cm (6.5") ceiling speaker with corrosion free grille (RAL 9010), suitable for the installation in suspended ceilings of any material. Equipped with a full-range driver. Quick snap-in mounting due to round ceiling cut-out through which the speaker with transformer and mounting ring can be installed. A screw terminal block (ceramic terminal with thermal fuse) allows the connection to the 100-Vnetwork including the eventually necessary level adjustment. Easy installation provided for the grille by a quick-mounting bayonet and for the protective cap by snap-in springs.

3.6 cm (1.4") miniature speaker with a plastic basket, plastic gasket and plastic diaphragm. Ballanced frequency response and good voice reproduction. Particularly well suited to outdoor applications and where ambient conditions are generally unfavourable (e.g. high humidity).

*) IP protection class for front side when built into a sealed enclosure

Wall-mounted speaker with a white plastic cabinet and metal grille. Fitted with a full range driver and a 100 V transformer. Clear speech reproduction properties. Connection to the 100 volt network and level trimming by means of screw terminal.
