Just wondering if you could explain something to me since you seem to be the in house exp. You know the new pioneer premier HU that retails around 630? Well the guy at my local shop who was telling me about it's features said that it actually comes with a microphone and a CD that plays a certain type of noise, you pop in the cd. close your doors and windows, attach the mic, it will actually adjust the direction the soundwaves travel in so that they are set up perfectly for the driver ... this sounded like utter BS to me, but if it's not how does that work ... especially with non pioneer tweets/cones etc...?

 

It's true....not worth it though
