[QUOTE="THATpurpleKUSH, post: 8684536, member: 615398"] If you are bottoming those out in .75 sealed then you are over driving them. What kind of amp do you have and how did you set the gain? The problem you are experiencing is the result of one or both of these: incorrect amp settings and/or damaged equipment. When you input paramters in to WinIsd you should fill in these as normal: fs, vas, qms, qes, re, xmax and bl. When you enter these numbers it's very importsnt that you have selected the correct unit of measurement as well. Once your driver information is entered then you have to create a design, pick your box type and input information about the desired box that you want to model. You dont just enter driver info alone and it spits out a graph. Let the autofill happen for qts, sd, cms and both db spl figures (1w/1m and 2.83v) since these are all calculated based on what you entered from above. One important bit of information about WinIsd is that it cannot calculate cabin gain aka transfer function. This means that it is not accuate below 50hz (95% of the bass you hear) unless you have a completely open listening environment. For this reason WinIsd is not accurate for car audio and instead Bass Box Pro should be used. I understand that WinIsd is free blah blah blah. You get what you pay for. Bass Box Pro even comes with a highly informative 1 inch thick user manual and they even walk you through step by step from start to finish and even a little guidance on analyzing the different graphs.
