Where I came from, people always recommand MK subwoofers if money is no object. I checked with Tom's chart, and found that specs alone, the sub I have, Hsu VTF-2 (I got it for $342) blows M&K MX125 mkII (can be had for $935) out of the water. When I ask those people who recommand MK subs, I always get replies like: "louder is not always better" and "smoothness is important, too" blah, blah... I can not understand how people can recommand a subwoofer not as good as another costing only about 1/3 as much. Perhaps there is something to it in MK subs.. Since MK subs are so widely used in professional recording studios, maybe they are looking for other things that I don't know about. So, has anyone directly compared MX125 mkII with Hsu VTF-2? or any subwoofers out there that have similar performance with VTF-2?
