Introduction/General Description

The Magneplanar DWM is a dipole, thin-film planar/magnetic woofer which is a derivative of the MG 20.1 DiPlanar

woofer technology. The DWM can be driven simultaneously by 2 separate amplifiers (typically the front left and right

channels). A built-in crossover provides a high-pass output for use with "small" Magneplanars.

Carton Contents

1 - DWM Loudspeaker with base

1 - Magnepan "Shaped" Pink Noise CD Test Disk

1 - Hex Wrench

2- 2 ohm, 25 watt resistors

1 - Speaker Logo

1 - Owner's Manual

Packaging

Save all packaging. The DWM can be shipped safely only in the original packaging. Should you discard it,

packaging is available from Magnepan.

Installation and Hookup

Install the base with the 2 screws. It may be necessary to realign the dowel nut in the speaker before installing the

base and screws.

Connect the speaker wire to the amplifier input on the DWM, obvserving polarity. Connect the "small" Magneplanar

to the output of the DWM, observing polarity.

5. Placement as a general rule, dipole speakers produce the deepest and most linear bass and midbass when positioned approximately 4-6 feet from the front wall or 1/3 of the way into a room. This rule may conflict with the necessity to have correct time alignment with the "small" maggies. Since room...

6. Phasing the magnepan pink noise cd test disk included with your dwm can be used to determine if the dwm is in acoustical phase with your limited bandwidth magneplanar. The test cd has a 9 db peak at 80-100 hz that draws attention to the frequencies which will be depressed in an out-of-phase condi...

7. Bass attenuation if it is necessary to reduce the output of the dwm, remove the bass attenuator jumper and insert a 25 watt (or higher wattage) resistor. Typically, 2 ohms is sufficient for most installations where bass reduction is needed. If a large amplifier and/or high power bass levels are u...
