Not to defend Magico, per se, because I can't say that I'm a fan of their products, one thing to keep in mind is that if the QSub-18 could indeed do 121db at 1 meter at 20Hz it would outperform the SVS PB-13 Ultra, tuned to 20Hz, by over 10db, and the more pedestrian Funk Audio 18.0 or the Velodyne DD18 Plus by about 17db. I really don't care one way or another, because I wouldn't keep such a beast if someone gave me a QSub-18 for free, but, assuming it really could do only 121db at 20Hz, it would be far and away the best commercial subwoofer Ricci has ever tested.
