The VMPS speakers are certainly capable of prodigious bass, but are not tuned that way. That's part of the advantage of going fully active - you are free to retune the speakers to your liking. For example, if you think the planar mids are crossed over too high and the resulting mid-treble beaminess bothers you, it's a simple matter to lower the crossover point a few khz so the midpanel is not producing any sound waves wider than 2 inches (the width of the panel). Same with bass. Because the DCX has 60 memory slots, you can have one memory setting that is "flat", and the next setting could be bass boost of +3db, and a third setting could be a bass boost of +6db, etc. And, the mid-panels have a slight low-treble boost which the DCX lets you take out pretty easily.
Actually, given how much flexibility going active gives you in tailoring the sound (from different EQ's, room correction, and amp swapping for each driver), I'm surprised that active systems are not more popular.
