[QUOTE="winkychevelle, post: 8817271, member: 611804"] Yea 28hz is the lower limit of what I shoot for because you stop hearing the sound below that and more just feel it. It also starts to tear things up as you get lower. My pair of sa10v2 would play 25hz quite well but it was more flexing the truck and I would hear the panel flex(roof) more than the bass. And of course as I raise the frequency the ear starts to hear sound and the panel flex gets less severe. This new 6th order I've designed is designed to be within 3db from 30hz to 65hz and cabin gain will allow it to go lower. I need to re measure cabin gain and do some deadening before finalizing and building that 6th order design. My mids while I'm happy with the silverflutes I'm considering trying to mount a 3.5inch mid in the kick or on the dash and run a larger 8inch midbass. The jp77 amp just looks too good to not try a 3way setup though I hate the complexity in tuning I'm getting the bug to try 3way again [/QUOTE]
