  • Any Maggie owners here? *PIC*




    Hey Guys,

    I've recently been toying with the idea of build a sub (or subs) to augment my Maggie MG12's. My dedicated listening room is smallish, about 11' x 12'. I have the walls well treated with some pyramid foam as well as bass traps in the corners of the room.

    In the present configuration, the Maggie's bass output is surprisingly good and I could live with them sans a subwoofer. But it would be nice to be able to fill in a little more of the bottom octave and add some "kick" to the system.

    I'm open to all suggestions. What I don't need is a subwoofer that just booms and thuds. My space is limited so I have been thinking along the lines of a 10" stereo pair. The Dayton RSS 10" subs look interesting.

    How to blend the subs properly is of course a concern. I don't really want to go the "active crossover, passive sub" route. I am hoping to keep it simple by using a plate amp(s) to power the sub(s).

    I do like the feature set (parametric EQ) of the 1000W amp that is currently on sale. It seems to offer alot of lexiblility in getting the sub dialed in just right.

    So:

    1 sub or a stereo pair?
    10" Driver or other?
    Dayton driver of other?

    Any insight would be appreciated.

    I've got a pair of MMGs...

    Each is sitting on right-angle stands on top a 0.7Q sealed Q15... Amps are a pair of 240s, and are dialed WAY down... The crossover is probably around 45-50hzish... I think the large cone area complements the MMGs.. Previously, I had a 10" that was in between the things. Didn't like it.

      Yep taking the midbass load off the panels makes a big difference. Ideally use a dipole woofer, something that's smooth up to ~250-300Hz. That gives you room to experiment.

      Crossover mods are another project well worth the work.

        I like the way maggie bass sounds... I just use the subs to fill, rather than to take over the low end.

        I mostly listen to bluegrass and jazz upstairs... Downstairs is more of a "brute force" setup.

          Hey whatever floats your boat. To my ears taking the midbass workload off the panels gives the upper frequencies better detail/clarity and allows higher power handling.

          I've used planars of some form or fashion since the mid 1970's. If one has TONS of radiating area then they're fine to run down to 80Hz or so.

          The mains in my primary listening room run down to 80Hz and the lowest octaves are handled by an IB sub

              That's how I tend to look at it too. I'm crossing mine at 80hz, but that's as low as the electronic crossover I'm using will adjust. With stereo subs, and the close proximity, integration is fine.

                In a room that small, you may well get by with a good 12". I would recommend a low-Q (<0.6 if F3 is lower than 35Hz) sealed enclosure or an IB setup. The bass is just more natural sounding and compliments the maggies natural sound. It is difficult to integrate a sub properly with maggies. In my case, I actually think mine image best without the sub, but I also believe that last octave makes the music sound more effortless and natural, so it's a tradeoff.

                Good luck!

                  Hey Nik,

                  I really like the Delta series stuff. I used to own some of the older Classe' gear, as well as some Simaudio Moon gear. The Delta stuff has removed my desire for any further upgrades.

                  The on-screen displays, while not everyone's cup of tea I'm sure, make for a very intuitive and easy to operate piece of gear.

                  Sonically, the unit's are very transparent and neutral sounding to my ears. I have the CP-500 preamp and CDP-100 CD player (now discontinued).

                  They're keepers. Now if I can just get that CA-2200 amplifier, I'll be set

                    I thought yrs ago, about buying a pair of the small Maggies, and building woofers to reduce the bass load. I looked around, and thought about trying the Pioneer A30IR50-51F (PE#290-118). Should have similar tone/timbe, quick transients, limited Xmax, and well damped/ribbed/rigid paper cones to blend with non-dynamic transducers. Fs of 19... should be a good all 'round woofer... not real expensive, could do 2 or even 4!

                      Maggie's over here!


                      I think you're on track with Dayton RS subs. IMO you should go with a larger sealed one. Sealed for low distortion and more displacement means better integration with Maggies. I have a 12x12 room and use a 15" sealed sub (not a RS). It's such a low distortion design that even using my receiver's 100hz crossover, it sounds wonderful.

                      Lotsa displacement, lotsa power, low distortion, low x-o point. That should do it.

                        A few thoughts. Regarding whether to run to subwoofer into the midbass versus augmenting the lowest octave, I would say that's a preference based on whether you want them to play louder or to extend lower. By crossing at 80 Hz or higher, the woofer panel isn't moving as much so you can increase the overall output -- the assumption here being that excursion of the woofer panel limits max spl of the speaker. On the other hand, if overall loudness isn't a goal, then I'd say do like Bogie and just add low bass. I like the sound of my MG-1s' bass as is and if I go with a sub, I just want it to operate 40 - 50 Hz and below.

                        For a sub design, my recommendation is to go as large as practical, i.e., 15". Or maybe two of them. A 15 driver can produce the same spl as a 10 or 12 while moving much less. 15" and larger drivers also tend to be able go lower in general. The Dayton Ref. 15...Quatro 15...both would go great in a reasonable sized sealed enclosure.

                        The idea of a dipole too is interesting to think about for use with maggies, however it gets harder to get the lower frequencies without equalization.

                        My $0.01 and keep in mind I just have some old tattered MG-1s and I've never operated them with a sub...

                          Re: Any Maggie owners here?


                          I've had a pair of MMGs for nearly three years now and loved the things. I run them full range and for bass augmentation I came up with something that's not quite a sub but for all intents and purposes is working like one.

                          I got a pair of the 1 ft^3 sub box kits from PE along with a pair of sub plate amps. The driver I used in each was a regular Peerless CSX 10" in each box, sealed. I keep the amps set to 40 hz for the xo and adjust the volume to blend after getting the phase switch set and so far it has worked out better that I ever dreamed it would. The cubes sit on the floor behind each Maggie, up against the wall behind them. I've tried them as "stands" with the MMGs sitting on top of each but did not care for the sound as they were just too high up. In my room and for my listening position, they sound better on the floor.

                          For a while I was highpassing the MMGs at 80 hz to keep the panels from being over driven but when I compared the sound with and without the MMGs filtered, I determined that I like them better unfiltered, running full range, with the bass cubes set to 40 hz. The blend is perfect and seamless.
