ME 802K 4-way-coaxial-floorstanding-loudspeaker with cardioid radiation characteristic in bass range

The 4-way concept of the ME 802K comprises three 10-inch woofer systems, 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 eight metres, rendering a natural sound image in stereo and multichannel operation.

ME 802K The optimal sound transducer for long listening distances

ME 802K

The 4-way concept of the ME 802K comprises three 10-inch woofer systems, 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 eight metres, rendering a natural sound image in stereo and multichannel operation. Two 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 125 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.

ME 802K

The vertical arrangement of the 10-inch woofers provides a directivity index that ensures realistic bass presence even at listening distances of up to eight metres. Our reliable K Technology minimises rearward-directed room reflections in the bass range and simplifies the positioning of the ME 802K in the listening room. If required, the three 10-inch bass units can be operated as subwoofers via the LFE input.

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 in our loudspeakers.

All these features make the ME 802K so unique on the loudspeaker market. It is ideal for large listening distances and for acoustically less attenuated rooms.
