ME 150 3-way-coaxial-floorstanding-loudspeaker in vented box
"No ifs and buts, Joachim Kiesler succeeded to build an extremely living-room-friendly passive loudspeaker. Its sound keeps up with the paramount performance of the active monitors. A down-to earth speaker that does what it was created for – passing on the music just as it is being supplied."

ME 150 Convincing impact through excellent converter linearity
The two 6.5-inch cone loudspeakers of the ME150 passive 3-way floorstanding loudspeaker are responsible for the reproduction of the bass and mid frequencies and convince with excellent converter linearity. Both bass-midrange systems are placed in a bass-reflex cabinet with a downward-radiating exit opening. This design simplifies the positioning of the loudspeakers for achieving optimal bass reproduction in your listening room. A 1-inch calotte serves as tweeter unit, located coaxially in front of the upper bass-midrange system. The particular radiation characteristics, in connection with the coaxial arrangement, allow a homogenous and natural sound image for a basis width between 2 m and 3.5 m. Using a suitable AV receiver, the ME 150 floorstanding loudspeaker can be complemented with a subwoofer from our BASIS series.
The general concept of the passive 3-way coaxial loudspeaker ME 150 is characterised by its well-balanced and low-distortion sound image and its high dynamic qualities.
