Excellent point. While subs may not be required for the 20 series to produce a wonderfully grand musical presentation in a properly set-up listening room of moderate to large size, a good coherent subwoofer system would be a prudent investment for mid-sized and smaller Maggies. Subwoofers, when positioned to maximize their benefit, can be a game changer. A well positioned subwoofer system should be capable of alleviating any perceived thinness not correctable through room treatments.
That said, I'm not convinced that two subs are an absolute necessity to achieve coherency for 3 series (dependent upon room size and acoustics) as the natural low bass roll-off of mid-sized Magneplaners can be finely tuned to match a single, centered, sealed box sub of sufficient power and size (15" or larger) positioned between the main speakers. Also, this can be achieved without an active crossover. If the sub's cut-off is set low enough to match the Maggie's lowest bass output any perceived distortion from overlap should be negligable. Note: To my ears the lowest octave isn't noticeably directional; other's mileage may vary.
Some folks recommend active crossovers between Maggie bass panels and sub(s). If utilizing two subs (esp. modestly powered subs under 15") with 3 series or smaller Maggies and setting the subwoofer's high cut-off point above 50-55 Hz this would probably be advantageous as the transition to mid-bass (above 62 Hz) is where sounds get much more directional. I can certainly see the benefits of an active crossover in a variety of settings dependent upon the frequency range and output of the main speakers. This is where experimenting can often pay big dividends.
Note: My assessment is not intended as an argument for or against anyone else's experience. I respect everyone's viewpoints and perceptions.
