I too an frustrated with the 4000x X over points, and resultingly, the sound stage that is obtained. However, I did find a solution for myself as towards how to raise the stage and maybe this can be of some benefit, or at least, give you an additional option. With my midrange and tweets being placed in the kicks (and midbass in the door), the image is very clear and sharp, but the stage is not as high as I was used to hearing with my factory honda (2001) dash tweeter positions. So, I decided use both areas for my tweets. I'm now in the process of getting an additional pair of tweets, and running these in line with the other set of tweets, only the new set will use a passive X over set at around 14-15,000 and up. My biggest challenge now is where I place these tweets on the dash. I'll probably integrate a molded piece similar to the way the tweets are positioned in the lexus sport utility vehicles (RX or RL...can't remember). Most likely I'll position them at the same angle as is the kicks, but with the additional tweets being X over so high and being placed level and on the dash, the resulting psychoacoustical nature of this setup SHOULD trick my ears in beleiving the stage is much higher, though it is really not. I know this option is somewhat elementary in its thought, but perhaps this may work for your setup. If not, I'm sure you will find the right tweeter, or some way, to highten your stage.

Even the best tweets like the Focal TLR are somewhat useless with the crossover selection the 4000X has. I have had the best sound from level matching every driver in the car. Place RTA in the center of the car and play pink noise. Find a spl level that does not distort (Make sure EQ is flat). Now do each speaker at a time(Defeat every speaker except the one you are working on) measure the spl and set to a reference spl(One that does not distort) Do this for every driver in the front stage. Last do the sub integration by adjusting to better integrate low frequency to your taste. After finding gains for all speakers to same spl set all driver to the according gain/spl structure. This should make a big improvement. Think of it like this. Home monitors are the same volume and produce very similar responses. This is a far cry from being true in a mobile enviroment. This can help compensate for the enclosure diffeneces. If you don't like it just go back to the last setting. --- Patrick Freeland wrote: > --> XDP4000X-List message posted by: "Patrick > Freeland" > > > Hey, right off hand I'm not aware of tweet with > those kind of specs, though > I'm sure something quality is out there that you can > find.

That will definately add more "Air", but I am really looking to get most of the upper mids from chest height or higher (like a home system). I think I might go the "quad-amped" route and build some pods with a small mid and tweet. I have seen this a lot lately. This will still let me use a higher crossover for the tweet, therefore increasing power handling and reducing distortion by reducing the tweet's excursion. This seems to be the most logical (but hardest) way to get what I am looking for. If they can mount a 5.25" or 6.5" in an a-pillar, I hope I can get a measley 3" mid in there with out much headache.
