Lowther PM6

 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.
