Aimed at dramatically reducing the most destructive distortion effecting the midrange and bass, DALI’s patented use of SMC (or Soft Magnetic Compound) eliminates electrical conductivity inside the woofer’s motor system. Eliminating electrical conductivity in the magnet stymies hysteresis, a principle source of 3rd and 5th order harmonic distortion. The result is vocal and bass performance with remarkable lucidity and excellent timing.
DALI’s signature red hued woofer cones are about more than just beauty. If you look closely, you will see individual strands of laminated wood fiber, applied in such a way that they reduce unwanted resonance without adding mass. These cones of remarkable strength and stiffness produce accurate dynamics and musical scale with excellent detail and openness.
DALI’s hybrid tweeter system is really the best of both worlds. You get the snap, dispersion and extension of a ribbon, and the smooth and natural presentation of a dome. To do this, DALI uses the ribbon as a quasi super-tweeter, passively rolling into a slightly oversized lightweight dome, with virtually no overlap between the two. This allows each respective part to work within its ideal range. Domes are most comfortable in the lower treble area, and ribbons at the high frequency extremes.
Fast, open and transparent bass and midrange need to meet with equally impressive treble, so DALI has worked hard at reducing the mass of the tweeter domes to improve transition to higher frequencies. These lightweight domes produce uncanny detail and are fast enough to keep up with DALI’s lightning quick woofers. Additionally, the domes can be tuned for use with or without hybrid ribbon super tweeters.
In keeping with the low loss principle, DALI speakers use hand assembled crossovers that feature point-to-point wiring that eliminates the normally subtractive PCB (or Printed Circuit Board) and allows for optimal placement of components. This seemingly simple technique drops distortion caused by the crossover and improves driver integration for better coherence and resolution.
Low Noise Cabinets
Cabinet-born noise comes in three forms: panel resonance, internal turbulence, and leaks. Great care is taken in reducing turbulence inside the cabinet so that this is not passed on a noise heard through the driver cones. Internal bracing and damping, used to reduce panel resonance, are located precisely to allow for the smoothest movement of air. Bass reflex ports are located to further reduce turbulence while maintaining proper timing, often directly behind the associated woofer. Every mounting surface has a gasket and every joint is properly sealed.
