Magnepan DWM - Manual (Page 3)

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 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.
It is generally understood that placement of subwoofers is very flexible. While
subwoofers do offer more latitude in placement due to the long wavelengths at
low frequencies, technically, there is an ideal place in a given room for
optimum subwoofer performance. The DWM is a woofer, not a subwoofer.
And the superior performance of the DWM, as compared to a subwoofer, is
due in part, to extremely wide bandwidth (flat to 5 kHz). The DWM can
seamlessly cross over at a higher frequency to any of the limited bandwidth
“Maggie” models. However, the higher crossover points require proper time
alignment to achieve the most seamless blend between the DWM Bass Panel
and the limited bandwidth Magneplanar. Therefore, the DWM should be equi-
distance from the listener to the limited bandwidth Magneplanar. Minor
adjustments from that position are often necessary for “fine tuning” as
described under “Phasing” below.
The DWM should be oriented so it is perpendicular to the side wall and
playing down the length of the room as shown in Fig. 1 below.
The DWM Bass Panel 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 will reduce dipole cancellation.
If two DMWs are used, the midbass response may be improved and smoothed
by placing the bass panels at different distances relative to the listener.
