ME 803K

3-way-coaxial-compact-loudspeaker with cardioid radiation characteristic in bass range

The 3-way concept of the ME 803K consists of two 10-inch woofer system, a 6.5-inch high-performance midrange system and a tweeter array with three vertically arranged 1-inch tweeter calottes. The directivity of the system has been optimised for listening distances of between three and six metres, rendering a natural sound image in stereo and multichannel operation.

ME 803K

The 3-way concept of the ME 803K consists of two 10-inch woofer system, a 6.5-inch high-performance midrange system and a tweeter array with three vertically arranged 1-inch tweeter calottes. The directivity of the system has been optimised for listening distances of between three and six metres, rendering a natural sound image in stereo and multichannel operation. One 1000 W and two 500 W amplifier modules supply the bass, mid and treble channels with sufficient power. The resulting overload safety ensures that even signals with highest peak levels are not limited. Also, sound pressure levels of up to 122 dB can be performed without audible distortions throughout the effective frequency range. A room compensation network, integrated into the amplifier electronics, allows control of the room-dependent frequency response.

The vertical arrangement of the 10-inch woofers provides a directivity index that ensures realistic bass presence even at listening distances of up to six metres. Our reliable K Technology minimises rearward-directed room reflections in the bass range and simplifies the positioning of the ME 803K in the listening room.

The low-discolouration and low-distortion characteristics of the 6.5-inch high-performance midrange system result from the intelligent combination of several construction details. The cone loudspeaker, for example, runs without contact to the enclosure, thus avoiding the problem of cabinet resonances. Instead the midrange system is operated with a rearward-directed acoustic flow resistor in order to achieve the desired directivity.

Frequently used wave guides in front of tweeter systems make directivity control easy. However, they tend to produce unavoidable discolourations due to short-time reflections on the inner horn surface. We take a different approach by using a tweeter array and doing without horn loudspeaker systems for sound level enhancement. The tweeter unit that is arranged coaxially in front of the midrange system guarantees the trademark low-colouration reproduction of sound events by our loudspeakers.

All these features make the ME 803K so unique in the loudspeaker market. It has been optimised for large listening distances and for acoustically less attenuated rooms.

Important information about deviations from sample pattern

Wood is a natural product. Even the most thorough manufacturing can result in deviations in colour or structure and is no cause for complaint.
Images are represented differently on every screen and hence not colour-proof.
