|That means that there would be a 3Hz gap if you set up a THX system with a 80Hz crossover because the speaker is actually limited to 83Hz?|

on a speaker what does it mean "-3dB point = 80hz?"
In adition to that could someone point me to a site that explains frequency responce as well as those speaker charts like in Sound and Vission.
|Right at the crossover frequency, the main speakers and the sub are each producing information at the same amplitude. If the sub is 3 dB down and the mains are 3 dB down, the sum of the two equals 0 (zero) and the frequency response of the system is flat at the crossover frequency.|
|If your mains and your sub were both 0 dB down at the crossover frequency, you'd have a +3 dB bump.|
