[QUOTE="Doxquzme, post: 8874360, member: 689267"] LR on midbass and tweeters, usually 24 db depending on the drivers and integration goal and the RTA once set up. For subs, usually 12, sometimes 18, sometimes 24. All of them are unique to specific setups/configurations. Open cabin or trunk? Ideally the sum of the crossover points is equal or flat, that is the goal for initial tuning. Running the drivers out of phase is not necessarily a bad thing either. 24 db is more common on the top end of the subwoofer cross inn open cabins versus maybe a 12 to 18 in a trunk, again as much environmental as anything. You could have just reversed the phase on the output via tha amplifer if the amp has that option which many do. Or, could have left the 24 db in place and reversed the speaker input wires too. So now that you have it all "in-phase", does it sound right? [/QUOTE]
