Hi, how many of u agree playing Audiophile quality in car, using EQ minimum 28/30 band is a must to correct your acoustic response and also bring the musical more live. I Choose with EQ because witout it like drinking coffee without sugar smile.gif Do share your comment on this

but this eq is old tech, ive it only because i got it cheap

agree...

but need to be careful to fully utilize it.

its not a tool to completely alter how the system response to audio signals but to correct the end production of the sound.

thats my take on the whole eq thing.

cause he is thinking about home hifi theory n setup. no eq mah. why should I have an eq in car too...
tell ur friend to put a glass on each side of the listening position in home hifi. n experience the sound

btw some hifi speakers oredy have a network correction too at passive.some r simple correction n some has some has multople correction. it's a form of eq too. so eq is common juz not known to end user

50Hz
1. Increase to add more fullness to lowest frequency instruments like foot, floor tom, and the bass.
2. Reduce to decrease the "boom" of the bass and will increase overtones and the recognition of bass line in the mix. This is most often used on loud bass lines like rock.

100Hz
1. Increase to add a harder bass sound to lowest frequency instruments.
2. Increase to add fullness to guitars, snare.
3. Increase to add warmth to piano and horns.
4. Reduce to remove boom on guitars & increase clarity.

200Hz
1. Increase to add fullness to vocals.
2. Increase to add fullness to snare and guitar ( harder sound ).
3. Reduce to decrease muddiness of vocals or mid-range instruments.
4. Reduce to decrease gong sound of cymbals.

400Hz
1. Increase to add clarity to bass lines especially when speakers are at low volume.
2. Reduce to decrease "cardboard" sound of lower drums (foot and toms).
3. Reduce to decrease ambiance on cymbals.

800Hz
1. Increase for clarity and "punch" of bass.
2. Reduce to remove "cheap" sound of guitars.

1.5KHz
1. Increase for "clarity" and "pluck" of bass.
2. Reduce to remove dullness of guitars.

3KHz
1. Increase for more "pluck" of bass.
2. Increase for more attack of electric / acoustic guitar.
3. Increase for more attack on low piano parts.
4. Increase for more clarity / hardness on voice.
5. Reduce to increase breathy, soft sound on background vocals.
6. Reduce to disguise out-of-tune vocals / guitars.

5KHz
1. Increase for vocal presence.
2. Increase low frequency drum attack ( foot / toms).
3. Increase for more "finger sound" on bass.
4. Increase attack of piano, acoustic guitar and brightness on guitars (especially rock guitars).
5. Reduce to make background parts more distant.
6. Reduce to soften "thin" guitar.

7KHz
1. Increase to add attack on low frequency drums ( more metallic sound ).
2. Increase to add attack to percussion instruments.
3. Increase on dull singer.
4. Increase for more "finger sound" on acoustic bass.
5. Reduce to decrease "s" sound on singers.
6. Increase to add sharpness to synthesizers, rock guitars, acoustic guitar and piano.

10KHz
1. Increase to brighten vocals.
2. Increase for "light brightness" in acoustic guitar and piano.
3. Increase for hardness on cymbals.
4. Reduce to decrease "s" sound on singers.

you can put the eql at the line before the e-xover. then you can use the eq back... but it will be limited at some point la...

eq is not hard, and it's not every music got it's own eq. it's just how you prefer the music to be played make you think that every music got it's own eq...

It's not hard.U just need to spend some little time for it.Remember you are not playing in home,for car u need to scope your acoustic response & correct it otherwise i would say its a waste playing high end equipment in car.

The number of bands in an equalizer tells you how fine an adjustment you can make. A 10 band equalizer breaks up the audio range into 10 parts and you can adjust the levels of any of them. The Q of an equalizer tells you how wide a range each adjustment makes. Let us say a specific band is labeled as 100 Hz. A high Q high equalizer will only boost or cut frequencies right around 100 Hz and not really affect signals at say 70 Hz. A low Q equalizer generally affects a wide range of frequencies even though it may be centered at one specific one. Typically, the more bands in the EQ the higher the Q so the different bands are not affected by each other. Simple bass and treble controls have the lowest Q. Equalizers with only few bands are good for making general adjustments but bad for fine tuning. A 30 band equalizer is great for making specific adjustments and tailoring the sound exactly how you want it. A tool called an RTA (real time analyzer) is used in setting those equalizers. It gives the system a flat signal (pink noise) and shows the user what the system returns.

I dun have golden ears to set eq by listening to songs.
I used the JL Audio RTA apps from iPhone to set eq and subsequently adjust slightly to my own taste.
It's not a professional tools but at least there is something to start off with and it's free.
Give it a try so you will realize how your car cabin affect the spectrum.
Please share your opinion after trying.
