[QUOTE="tommyk90, post: 6329794, member: 545293"] Controlled chaos is definitely a good way to describe it. [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] The tuning part is a little more tricky in an SPL install. I'd wager that most serious SPL setups aren't built around a specific tuning frequency, rather the optimum box and port size/length that is derived after hours and hours of testing and tuning. For instance, I have no idea what my setup is actually TUNED to, all I know is where it PEAKS at and what score it does. To put it into perspective so others can understand, one day I was playing around with JUST port lengths. My enclosures use external aeros so changing the length doesn't change the airspace. However, in one instance I chopped 3" off the port length. Interestingly, my peak frequency stayed the same but I lost a whopping 2.5 dB. This is where numerous other factors come into play. Impedence rise, vehicle resonance, cabin gain, etc. Lots of things going on at once. The point I was trying to get across with the 10 mm vs. 10 mm thing was that motor force is a driving factor (literally, ha). As a real world example. Think of hitting a wall while counting off 1 second (i.e. one sine wave). You can hit the wall with little force in that one second, or you can put your whole body into it during that 1 second and punch through the wall. Same amount of movement in the same amount of time, just a whole lot more force behind it. At least thats the best way I can explain it. Honestly though, arguments about shit like this never end up well, as evidenced here. The funny thing is the people that argue about this are rarely ones who have ever competed or really built an SPL oriented setup. No offense.
