Magneplanar SMG

MAGNEPLANAR

SMG SERIES

Magneplanar introduced the SMG series in 1980, as less expensive and smaller planar magnetic loudspeaker than MGII series. In 1985 was commercialized the SMGa and successively the SMGb. The last model was the SMGc introduced in 1993.

Basically all models are 2-way planar loudspeaker, one screen for each side which contains mid-bass and mid-treble section (the so called quasi-ribbon). Aluminum wiring in both section. 4 Ohms impedance.

SMG (1980)

This one was larger than the next versions (24¼"×48½"×1¾") . Mid-treble: 58in² and mid-bass: 370in². Sensitivity 90 dB.

SMGa (1985)

Dimensions: 19" × 48". Sensitivity: 90 dB. Max Power: 150W.

The speaker input panel is slightly different than the previous version.
