[QUOTE="mat3833, post: 8794761, member: 587645"] OK, that's alot to answer but I'll try. Yes, it's a 3 way active setup. Full hertz Mille legend front stage. Ml 1650.3 midbass, ML 700.3 midrange, and ML280.3 tweeters. Aiming is on-axis at my face for the midrange and tweeters. Drivers side are aimed at the headrest, continuing to the passenger C-Pillar. Passenger side are aimed just behind the drivers B-Pillar. I'm still messing with crossover points and haven't even really gotten into EQ or TA yet. I switched from RCA to Optical signal so I had to restart everything over. It is possible I have some acoustical phase issues right now, all my crossovers are 24db L/R at the moment. I may be switching to 24db Butterworth for the midrange and tweeter so I can seperate the crossover points a little if I'm getting a peak. It's been hot as BALLS down here so I haven't gotten a ton done besides enclosure design for the subs and some minor tweaks here and there. I will be pulling some RTA sweeps of each speaker pair soon, but I do think I'm going to drop the tweeter down to 4k and drop the midrange down to 400hz-4k. I know the tweeter can play down to 2400ish, probably lower, but I have protection caps wired in on both midrange and tweeters so they can't play anything below 250hz(midrange) and 2500hz(tweeter). I'm currently waiting on the box guy to give me a quote and time frame for the box panels. He's been no-contact for about 10 days now... If it stops raining today I'm going to jump in the car and work on some basic T/A and try to get some level matching and RTA measurements done. Matt [/QUOTE]
