[QUOTE="Toxic Tuan, post: 6738500, member: 558678"] Tommy, first off...I'm not looking for your help. I have companies paying me to design their enclosures because of my knowledge. This has been working for me for years. If you're saying that no theories works in a car environment, then you might as well throw away all design softwares. And secondly you're assuming that no 2 vehicles are remotely close to another. This is purely not true. There are many factors and constraints that still holds. My tests are very valid and serves as useful data. In 2003, I designed a dual 10" rear horn enclosure with high compression. This was close field corner loaded enclosure. I knew the compression was high, but I could never have imaged it be that high. Were the compression was built, the one subwoofer would rip itself apart. The cone and surround would be completely torn. I measured the compression and recorded the data. After a few tests, I found the maximum allowable compression. This help me determined the appropriate horn choke ratio. Without these tests, this would never be possible. Some of what you're saying is true, but once again...you don't understand the constraints. Have you ever been asked to design an enclosure that will work well, to the best capability, for all vehicles...if not most? That is one of the constraints. Tommy, you're wasting your time telling me things I already know and you're uselessly arguing with me without knowing the intents of the designs. I'm just going to end it right there. Tuan [/QUOTE]
