PM6 Drive
Unit for use with Acousta Enclosures
The PM6 is
an 8 inch twin cone unit of similar design to the PM3, plastic foam suspension,
aluminum voice coil and a modified form of Stabilizer being used in the
construction.
The magnetic
structure, lathough not as large as on the PM3, nevertheless produces a gap
flux of 17,500 gauss - well above comparable units. All the benefits attendant
with such a large magnetic field are derived - minimum transient distortion -
greater efficiency - improved high frequency response. The PM6 has been
designed for use in enclosures which provide direct high and mid-frequency
rediation and produce the necessary rear loading in the bass range. Mounted in
such an enclosure the full capabilities of this drive unit will be realized,
ensuring smooth extended bass reproduction free of "boom" and "
one not bass", while in the upper range, reproduction will be well
balanced and crisp-yet not tiring.
The
performance of the Acousta - or any
similar enclosure - will be greatly enhanced when used with the PM6 drive unit,
Due to the
high order of efficiency of the PM6, fusing is recommended in order to prevent
damage resulting from overloading of the unit.
