[QUOTE="The Camry, post: 8633963, member: 657974"] On a good note though. Shes mean and power hungry. [IMG]https://uploads.tapatalk-cdn.com/20180324/3dc40630c61e7037ca284bee1029c4db.jpg[/IMG] [IMG]https://uploads.tapatalk-cdn.com/20180324/812b141808314b3fcba12b35e4790fa6.jpg[/IMG] So i've been playing with Winisd. All graphs are modeled in 200Cuft on 1 sub. If you model smaller, you get less excursion. Fi states its a 34mm One Way excursion, with xmax at 20hz on 600 watts. So i thought id model it.
