Just trying to think of different ideas to upgrade my system. As in increasing the bass/mid bass for music (Classic Rock, orchestral music soundtracks Tron, Lord of The Rings etc.). Things like buy a pair of used 20.1's, use my current 3.6's with a pair of DWM's, have someone build (not a DIY guy) a pair of conventional cone dipole woofers like Davey has.
Or perhaps going the DSP, vertical biamping route. Also I prefer my bass very tight. When listening to stereo I always have my receiver in Direct mode. Though I think my SVS Ultra Plus 2 sub, works very well when in home theater mode. Two of the three ports are plugged and crossover is set at 60hz, sitting on top a Auralex Subdude.
I did borrow a single DWM sub from a Maggie dealer a couple of years ago. However the results were not that great, I thought the crossover was set too high. I could hear Elvis singing thru it even in the
null zone. Though I think I read Wendell has a resistor you can insert now to help with this.
Dedicated dual stereo/home theatre room, 12'5 by 26' with a sloped ceiling. The 3.6's are at the low end, on the short wall. 10.1's for surround duty, bass traps floor to ceiling all corners, front corners have QRD's in front of traps. To the left of listening position I have an open doorway, leading into my kitchen, a hallway and two bedrooms and a bathroom.
Thanks for your help,
Troy

If you haven't already tried it, try replacing the stock crossover with an active crossover. One of the best upgrades that I had ever made.
The crossover is set a bit high for full range speakers on the DWM. That said, they are the Magnepan path to more mid and upper bass and lower midrange.
Here are my general learnings Aimed at the general reader, not Troy....
The keys to integration are:
1). placement of DWM. Every location has a different effect on smoothing peaks and valleys. It is like integrating multiple subs but for higher frequencies. If you don't have placement freedom, it is possible to create new peaks in the bass or lowest Mids (200 to 400 hz). It helps to have two DWMs rather than one, as you can put each in a different place, and don't have to put it in the middle of the speakers.
2). Attenuators. Magnepan sells an attenuator which rolls the speakers off faster. I found this to be of almost no value.
3). Resistors. These work great across the board. Experiment with values.
4). Placement of primary speakers. This is probably the most important issue. The perfect location for a full range pair of Maggies and a pair with DWM support is not the same place. You effectively change the speaker, and a different larger speaker with more upper bass power needs a different location. In general, I find DWM support allows, or even demands the speaker be further from the FW. At three to four feet, I would probably NOT use a DWM unless the room was huge. At six to eight feet from FW, I find three series really benefit, but have no experience with other models or sizes.
Get rid of the bass traps and use a good sub crossed over at 40HZ

Their was a lot of ringing and room boom without the corner bass traps, and this was not even using the subwoofer. Though I have thought about upgrading them to RPG Modex corner traps, which are membrane absorbers. Which are supposed to be more effective in corners and at lower frequencies.

Depends on what you are trying to do.
The 20.1 will give you more and better of everything and you can lower the XO on the sub to 30-40hz. Only if your room is rather large would you need anything beyond that.
If you just want a more extended more powerful bottom octave then get the Dayton bipolar subwoofer and you will have a solution. If it is not enough then get two. With two you can raise the XO to 80 hz and relieve the 3.6 from their heavier bass duties.
