hmm, I repost my respons (all that I can remember anyway

) due to npdang´s webhost change:
graph one is the first curve I competed with.
It earned me a dead last place finishing...
The judges had some not so nice comments about the sound, and when you look at the graph You see why...

Graph 2 is my latest curve.
It earned me a 3rd place finishing...
Look at the 20-50hz region, it differs 1 db from the lowest "peak" to the highest...!!!!!!!
I believe we looked at it in 1/36 or something and still couldn´t see any peeks/dips higher than 1 db, comparing the lowest to the highest.
Btw, the guy who made the RTA reading were close to ecstatic

The sub is a
Digital Design 3510c 2x2 ohm dvc
I hope this foil any questions whether DD is a db sub only or not...
It works really fine for SQ as well (Jassa Langford initial made them for SQ at the beginning, but since the DD´s can take such a beating, all the db boys/gals started using them)
The difference between the 2 graphs are two things, some EQ and different X-over freq and slopes.
Graph 1
High: 2,5 khz/6db - and up (Through), no attenuation
Mid: 25hz/6db(or Through, can´t remember which one) - 2,5khz/6db attenuated -2db
Sub: Through - 40hz/6db attenuated -2db
No EQ
Graph 2:
High: 4,3khz/18db - and up (Through) no attenuation
Mid: 25hz/12db - 5khz/18db attenuated -2db
Sub: Through - 50hz/12 db no attenuation
EQ:
-1,5 db at 315hz
+2.0 db at 1,25khz
The first settings resembles the Factory settings of my Dynaudio 240mkII system (I haven´t the x-over boxes, just the speakers).
Dynaudio utilizes only 6db on their x-overs, and the x-over freq is 2800hz.
The sound from my first settings were:
harsh trebble, lack of bass, ok midbass, lack of "feeling/body(thats the word we use in Sweden for this)/omph in the midrange/midbass"
And the singer/singers sound as if they sing into a cup or something...
Settings two on the other hand has close to everything I want.
Smothness, body

, omph, and so on.
The "cup" is also gone, mostly thanks to the 315hz adjustment.
I also got the maximum points (15p) in "listening pleasure".
And to be honest, that´s all I´m looking for: To see people smile when they listen to the car..
Maybe my system diagram has nothing to do with the initial question, but I wanted to give You all the "low down" of my system, and also show that there are more things to a systems integration than just adjusting the EQ
Best Wishes

Fell free to ask me any questions regarding my system
