Speakers sounding dull? MUST READ! The truth about speaker design!

The tweeter response will be modified by the cabinet it is placed in. This is loudspeaker design 101. 

There is no point arguing about this. Tim, you still think that you can design a crossover without knowing what the cabinet looks like. If you go on partsexpress or diyaudio, there will be plenty of experts on there who will quickly point out how wrong you are.

Thats interesting. But a speaker system has to reproduce the signal doesnt it? The only question remaining is how accurately it does this. Its not a matter of opinion because sound is nothing but movement of the air. You dont need a person to have sound. Either the sound is an accurate replica of the input or it isnt. Most of the time it isnt. 

Ive had more than a few different high end commercial speakers such as B&w, dynaudio to name a few in here to audition. Why dont they ever sound good then? If the speaker designers are so superior why did the speakers sound rubbish? Ive had dynaudio contour 20s here supposedlly one of the finest standmounts on the planet. They were horrific. Explain that then
