The Magnepan DWM Bass Panel is a dedicated planar magnetic woofer designed to extend the low-frequency performance of any Magnepan system without introducing the colorations of a conventional box subwoofer. By adding planar bass diaphragm area that matches the character of your existing speakers, the DWM fills in the bottom octaves while preserving the speed and coherence Magnepan listeners value most.
Note: "The DWM is a Bass Panel that's a woofer NOT a subwoofer. Please understand these expectations." - Michael Hoatson (owner of The Listening Room)

Key Features of the Magnepan DWM Bass Panel
- Adjustable Bass Area: Expands the effective bass diaphragm area of your Magnepan system for customizable bass output.
- Dual Bass Drivers: Features two bass drivers in one thin-film, planar/magnetic panel for powerful yet refined bass.
- Quality Integration: Integrates effortlessly with full-range Maggies, delivering consistent, high-quality bass across the frequency spectrum.
Design and Build
The Magnepan DWM Bass Panel's design makes it an ideal addition for any Magnepan system, offering enhanced bass performance while maintaining the clean, minimalist aesthetic Magnepan is known for. The DWM Bass Panel is essentially a compact version of the larger Magnepan bass drivers, making it suitable for different room configurations without overwhelming the space.
With its dual "voice coil" grids driving a single bass diaphragm, the DWM Bass Panel functions as an extension of your current speakers, adding depth and warmth to the bass. The panel's flexible positioning options allow for an ideal setup that minimizes standing waves and optimizes bass response.
Performance
The DWM Bass Panel is specifically designed to integrate seamlessly with full-range Magnepan speakers, allowing for consistent and cohesive sound. Unlike traditional subwoofers, which are often limited to very low frequencies, the DWM Bass Panel can operate effectively up to approximately 200 Hz, providing both mid-bass and low-end support that sounds natural and well-balanced.
For listeners looking to optimize bass without sacrificing quality, the DWM Bass Panel offers a solution that is focused on refinement rather than sheer quantity. By adjusting the positioning of the panel, users can achieve both phase and amplitude balance, optimizing bass response for their room.
Magnepan DWM Planar Magnetic Technology
The Magnepan DWM Bass Panel uses advanced planar magnetic technology, similar to that found in the larger 20.7 and 20.7 models. This technology ensures a precise and controlled bass response, avoiding the "muddy" sound often associated with subwoofers. Unlike typical subwoofers that operate below 40 Hz, the DWM Bass Panel provides high-quality bass that complements your Magnepan speakers throughout the mid-bass and low-frequency range. The dipole design of the panel provides even bass distribution, avoiding the peaks and dips common with traditional subwoofers.
Versatility and Compatibility
The Magnepan DWM Bass Panel is compatible with a wide range of Magnepan models, from the .7 to the flagship MG 20.7. Its flexible design makes it easy to integrate into different setups, whether you're enhancing a small listening space or augmenting the performance of a larger room. The panel's mobile nature allows you to reposition it as needed, fine-tuning the acoustics of your listening environment. Pair it with the LRS+, 1.7i, or 3.7i for a fuller, more complete Magnepan experience. It also fills in the low end for the on-wall MC1 in a home theater system.

How does the DWM connect, and does it need its own amplifier?
How does the DWM connect, and does it need its own amplifier?
It wires in line, not alongside. Run speaker cable from the amplifier to the DWM's amplifier input, then from the DWM's output to the Magneplanar, watching polarity; there are no left or right inputs or outputs on the panel. Whether it needs its own amplifier comes down to one test: if yours doubles, or nearly doubles, its power from 8 ohms to 4, it is a high-current design and can usually carry the DWM in parallel. If it does not, Magnepan says to give the DWM a separate amplifier.
Is the DWM a subwoofer?
Is the DWM a subwoofer?
No, and Magnepan would rather you did not call it one. It is a dipole planar woofer running 40 to 200Hz, essentially a small section of the 20.7's bass driver, with two voice-coil grids driving one diaphragm. A subwoofer is a separate category built for below 40Hz. In Mike's words: "The DWM is a Bass Panel that's a woofer NOT a subwoofer. Please understand these expectations." If you want the bottom octave under a Magnepan system, that is a job for one of our Perlisten subwoofers or a REL, alongside the DWM rather than instead of it.
How many DWM panels should I run?
How many DWM panels should I run?
One per channel in a two-channel system, so two, with one set of connections used for each panel. A single DWM has one diaphragm driven by two voice-coil grids, and when you run a pair each panel uses only one of its grids. Magnepan's own tip for a two-panel setup is to place them at different distances from the listening position, which spreads out room modes and smooths the midbass rather than stacking the same peaks twice.
Where should the DWM go, and how do I check the phase?
Where should the DWM go, and how do I check the phase?
Placement is deliberately loose because the panel is a dipole and its bass output changes with proximity to walls and furniture, which is why Magnepan's response figure carries a caveat rather than a promise. Set it, listen, move it. Phase is easier than it sounds: turn the panel 180 degrees and listen; the orientation that gives the loudest peak is the one in phase. Save your money on cable here, since a power resistor is usually needed to attenuate the DWM anyway and heavy gauge wire buys nothing in this application.
Can the DWM fill in the bass for a Magnepan center channel?
Can the DWM fill in the bass for a Magnepan center channel?
Yes, and Magnepan documents the wiring for it. Connect the amplifier inputs in parallel, plus to plus and minus to minus, then wire the CC5 to the high output of one DWM, not both. The result is a nominal 3 ohm load, so the center channel amplifier has to be a high-current design. Done this way the center stays all planar instead of handing its lower range to a box speaker, which is the whole reason to do it.
