Frequency response "curve". This is what I was talking abou

A few months I posted a topic about how you like your freq. response curve and that a guy who's been into home audio, as a profession, for over 30 yrs suggested a -.5 dB drop every Octave from 20 Hz to 20K Hz. I was informed years ago that a flat response from 20K Hz down to around 200 Hz and then a slight bump of 3-6 dB in the remaining freqs. Gradually going up and down.

Here's a guy that has a combination of the 2. Look at his graph, I don't care so much about the thread, but it does somewhat explain what I was talking about.

that's quite a nice frequency response, not sure what the step response graph below is though :?:

when i was a bouncer at a club, on goth night the chick that was the D.J invited me into the sound both, she said i could chose some songs to play so i did that. but i also started tweaking the eq, i pulled some out of the very low frequency's to stop the subs from bottoming and also tuned the harshness out of the high's and made it smoother. the funny thing was a girl that went to the club alot, said she liked what they did to the sound, and asked if they had new speaker's or something. :clap:

Frequency response from the system in my old Mitsubishi Colt. Focal TLR tweeters from 2khz up, Hertz 5" mids from 2khz to 80hz and dual DD1508s in a large low-tuned ported box. The curve would suggest that the low-end was overpowering the rest with massive and bloated bass, but actually it sounded really tight and precise. And you need a lot more output in the low end while listening to music when driving to combat road noise/droning.
I bet I could have made the curves smoother with more eq bands (using a 90s Pioneer P99R with 13band eq here), but it sounded pretty smooth and linear in real life.

Thank you, you understand where I'm coming from cause you've "lived" it. Even though the bass (and this was the main issue in the earlier thread concerning this) looks over done, it's actually what sounds the best even in SQ terms. Just because it looks overdone, doesn;t mean that it sounds like ass. On the contrary, it actually sounds really freakin good.

i was at my friends house last night that has a studio, he has recorded some tracks for big name artist, he let me hear some tracks that he made more recently. i thought i knew alot about eq's but watching him adjust the eq on one of his sound boards made me think. some of the bass tracks he let me hear i believe have the potential to break the glass out of a car with some strong subs, of course he's on a whole nother level. :)
