I think it should be fine, as long as you use a sharp XO like an LR4. I'm not even sure you need a dipole sub at that frequency -- it's below the modal range of most rooms (though a dipole sub has a major advantage when it comes to not disturbing your neighbors). If you use a steep crossover like an LR4 you should be OK, the radiation pattern will transition from dipole to cardoid to monopole. (All speculative, of course -- I haven't heard this combination.)

Anyway, you could go with Linkwitz, a Ripole, or an H-frame like the GR Research. Smaller drivers sound better in the range above, but in the bottom octave, I don't think you'll hear a difference.

I have considered the Magnepan DWM, but its frequency response only down to 40Hz. If not, it would be very ideal.

  Yep, it isn't a subwoofer, more a woofer that can be used with smaller Maggies like the Mini Maggies or the home theater speakers, or to improve bass with a planar like the 30.7 in a large room (as the room size increases, you need more diaphragm area). The new Maggie woofers should mate brilliantly with a Quad, but they're also woofers rather than subwoofers so if you're going to run the Quad down to 40 Hz they wouldn't serve a purpose.

    Now I understand. Rumour has it that a company called TBI made a subwoofer that is very low mass, and it should mate with the ESL perfectly.
    
    The Linkwitz LX521 bass section LXsub4) might be the one to go for, this is because I have listened to the LX521 Reference not long ago, the tone of the deep bass should track the ESL-57.
    
    Sadly, I cannot borrow the Linkwitz bass from the LX521 owner for trial :-(

      I think it would be a good choice, though I saw someone complain once that the drivers in the LX-521 sound discontinuous. (To my frustration, I've never heard it myself.)
