5 cm (2") miniature speaker with plastic diaphragm (Mylar). Very compact design. Good speech reproduction. Differences to K 50 FL - 8 Ohm: Higher resonance frequency Higher mean sound pressure level Adjusted frequency response *) IP protection class for front side when built into a sealed enclosure

Electro dynamical exciter for stimulating bending waves on plates. The unit can be attached to the surface of the plate by gluing or screwing. Please find further information on exciters here: Basic principles of exciter-technology (PDF; 388 KB) *) Maximum long term power according to DIN EN 60268-5

9 x 15 cm (4" x 6") full-range driver with tweeter cone. Wide and balanced frequency response. Well suited for speech and music.

2.8 x 4.0 cm (1.1" x 1.6") miniature speaker with paper cone and rectangular plastic basket. Small dimensions due to neodymium magnet. The excellent interaction between the different components achieves a very linear frequency response. Connection via soldering points on rear side.

4 x 9 cm (1.6" x 3.5") full-range speaker with wooden cone and stable plastic basket. Flat and lightweight design because of neodymium. The cooperation of the separate 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.
