ME 901K1

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

Great events often come from little causes. The ME 901K1 has been designed for music enthusiasts, which focus on the legendary sound of the RL 901K in the smallest possible cabinet. To minimise the size of the cabinet the amplifier module is housed in a separate cabinet.

ME 901K1

Great events often come from little causes. The ME 901K1 has been designed for music enthusiasts, which focus on the legendary sound of the RL 901K in the smallest possible cabinet. To minimise the size of the cabinet the amplifier module is housed in a separate cabinet.

Our reliable K-Technology is also used in the ME 901K1 and by the cardioid radiation characteristics within the frequency range from 30 through to 250 Hz the reflections on the back walls of listening rooms can be minimised. In addition the transfer characteristic can be matched to the acoustical conditions of the reproduction room as well as to the set-up situation by an integrated room matching filter.

The unit for the medium and high-frequency range is combined in a coaxial manner with our long-throw 16-inch bass system and is provided with a directivity index, which supplements in an excellent way that of the bass system. The total directivity index of the monitor was optimised for middle and larger listening distances between two and four metres. The whole system is superior by excellent localisation behaviour. Moreover, a series of constructional measures provide that convincing lowest values of non-linear distortions and colourations could be reached.

The concept of the active 3-way coaxial speaker ME 901K1 offers a high sound compatibility to the RL series and convinces with phenomenal spatiality.

Additionally to the ME 901K1 an elegant stand is available.

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.
