[QUOTE="blazian87, post: 8706809, member: 574798"] Are you able to make your slopes sharper like 18db or 24db? That would help tighten your sound in your midbass to bass reproduction. 100hz is a bit high for LPF. Try 80 or 63 @ 18db or 24db. You need to experiment based on your equipment and car. HPF for your focals will depend on how much sound deadener you have applied to your doors. If not much or at all then 120hz is fine but you will be missing some midbass. If you’re confident youR door rattles are under control, then bring it down slowly to 100 and 80 to see if they can handle them. Based on the FS of 70, they can easily go down to 80hz @ 24db but that will depend on how well insulated your doors are. [/QUOTE]
