You did understand me completely wrong. But you are aware how speakers with multiple drivers actually work, right?
I'm talking Class D amps and digital (matching and crossover) filters vs. analog amps and analog filters (crossover only). No DSP stuff. For each speaker you need a separate crossover filter (high-pass for the tweeters, low-pass for the woofers, bandpass for the medium sized ones). In a passive speaker these filters create huge losses - both in terms of signal quality and of actual power loss - because analog filters can only be so good. Even a 4th order. And you can't create a filter characteristic to match the frequency response of the driver and case. Because creating complex analog filters will create even more losses. With a digital filter and a separate amp per driver (as it's done in active speakers) you have no such issues. Effectively, the audio chain is much, much shorter. Analog: DAC - preamp - amp - filter-cascade - driver Digital: DAC - amp - single filter - driver --- learn more about iPeng, the iPhone and iPad remote for the Squeezebox and Logitech UE Smart Radio as well as iPeng Party, the free Party-App, at penguinlovesmusic.com *New: iPeng 7, the Universal App for iOS 7* ------------------------------------------------------------------------ pippin's Profile: http://forums.slimdevices.com/member.php?userid=13777 View this thread: http://forums.slimdevices.com/showthread.php?t=101924 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
