[. . . ] Introduction/General Description Carton Contents Packaging Hookup Installation and Placement Phasing Service and Shipping Specifications Introduction/General Description The Magneplanar DW 1 is a dipole, thin-film planar/magnetic woofer which is a derivative of the MG 20. 1 DiPlanar woofer technology. The DW 1 can be driven simultaneously by 3 separate amplifiers (typically the front left, center and right channels). The DW 1 is a "fast" woofer with flat response to 5 kHz which makes the DW 1 ideal for blending with all Magneplanar on-wall models or center channels that have limited bass response. 2.

[. . . ] Therefore, the DW 1 should be equi-distance from the listener to limited bandwidth Magneplanar. Minor adjustments from that position are often necessary for "fine tuning" as described under "Phasing" below. 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 rooms vary greatly, these setup instructions are principles of operation and specific and detailed instructions are not possible. Magnepan and our dealers can provide advice on the specifics of your room. The DW 1 will give the lowest frequency response if a boundary is used to reduce dipole cancellation of bass frequencies. A placement along a wall or next to a cabinet or piece of furniture as shown in Fig. The DW 1 should be oriented so it is perpendicular to the side wall and playing down the length of the room as shown in Fig. 2 6. Phasing The Magnepan Pink Noise CD Test Disk included with your DW 1 can be used to determine if the DW 1 is in 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 condition. Place the DW 1 next to your limited bandwidth Magneplanar and change the phase. (It is much easier to detect an out-of-phase condition when the "small" speaker is physically next to the Woofer. ) Since the DW 1 is a dipole woofer, the easiest way to determine if the DW 1 is in-phase is by simply turning the woofer around (180 degrees). If you are uncertain of the phasing, a technique which can aid in determining if the phase is correct, is by leaning over and positioning your head between the Magneplanar Woofer and the "small" Magneplanar as shown in Fig. [. . . ] Please include your name, address, and a daytime telephone number. 8.
