In Reply to: Rear-firing tweeters : gimmick or real improvement ? posted by Lambda on November 9, 2006 at 07:45:17:
"Interference" called 1/4 length wavelength cancellations (also known as destructive cancellations, or comb-filtering).This distortion of the frequency response can make the sound "more spacious", but not more accurate.
There's already too much comb filtering from room reflections -- adding a second tweeter, when one tweeter can provide sufficient SPL, can only make the frequency response worse at the listening position.
That's a sound effect or gimmick -- not an improvement.
However you always have a spare tweeter if the front one breaks!
