True event circle around middle 2002

Before Filtering

The woofer is Kicker's Sonic 12" square dual voice coil something something. Sorry, I never bother with woofers, they are always good. The purple color curve represent the woofer. It is mounted in a small box. Not good, but not terrible either. Usable to some extend.

Here comes the good part. Notice the green color curve. It is the 6.5" midrange. It is flat from around 90Hz to 600Hz. Then slowly rising into cone breakup frequency. The rate of rise is slow and steady. This will make life easy to apply filters :) ehehhehe

Then the diamond in the desert.

Please look at the red color curve. It is the tweeter. It is again literally flat from a very low 1kHz to 7kHz. It then dies quickly after that, which is extremely unfortunately. If this tweeter could continue it's flat range till 13kHz or more than slowly roll off, it would have been much much better.

Sweet :) DLS..............hey................. diamond in desert...................

Imagine if the tweeter can pull flat high into the 20kHz. Theoretically perfecto!!!!!
