[QUOTE="Ivan Beaver, post: 27001, member: 30"] Re: Got a quick question about the JBL MP418S subwoofer The tuning really only affects the around around the lower end of the response (where the tuning is) and has little effect on the response above that. Now that statement is only for ported boxes-not horns-or bandpass etc. If you take the same driver and cabinet and tune it for 30Hz it will be louder (at 30Hzish than other tuning freq) . If you tune it for 40Hz, it will be louder at 40Hz, but not as loud at 30Hz as a cabinet that is tuned for 30Hz. So each one can be "louder" than the other-depending on what freq you look at. When you only look at simple single numbers, you get "wrong" answers to the wrong question. Just because it is "tuned" does not automatically make it louder-only at the particular freq and response that it is intended for. There is always a "target" in the design process-you give up one thing for another and have to deceide which is better for the intended target market. I hope that makes some sense. [/QUOTE]
