Magnepan Magneplanar MGIIIA loudspeaker Measurements

Sidebar 1: Measurements

Fig.1 is a "snapshot" of the forward axial response, showing some lift up to 16kHz. The mid-treble is linear and well integrated, while the bass is more or less level to 40Hz, in good proportion with the rest.

The response in the listening room (fig.2) was remarkable at first sight, although the upper treble was just too good to be true. In addition, the moderate prominence at 60-80Hz could ideally have been avoided. This curve confirms both the inherent neutrality of the IIIa, and its new found extension to 25Hz in-room.
