Thought this might help them sell. Found it on Kenwoods site.
Bump for a good deal!


DualMags are lightweight, low-distortion, exceptionally clear-sounding speakers without the monster-sized magnets. They also fit where other speakers dare not tread. What our engineers did was put two small, powerful magnets inside the voice coil with their like poles pointing to each other (and a small plate in between), generating a much stronger magnetic force field than a conventional magnet of the same size. Compared to conventional speaker design, DualMags cut 2nd and 3rd harmonic distortions. And because the magnetic structure is inside an aluminum housing, all of the magnetic energy is precisely directed into the magnetic gap. The 4-layer voice coil helps to bring out its special strength - vocals. It's just like listening to singers live. Compare DualMags to other 2-ways. A DualMag(tm) sounds better and fits better.
