Equalizing the Crossover Point

[noob with an RS 10+ year member]

hey i've got a set of infinity perfect components up front and a single 12" idMAX in the trunk. they are being crossed over with an audiocontrol EQX and they are both crossed over at 52 hz EXACTLY (24db slope). ive got the EQ setup so that everything sounds almost crystal CLEAR. the only problem is i feel like im missing just a LITTLE midbass or lower-midbass from the components.. if i were to boost say, 60 hz, on the EQ just a little bit would i be hearing a boost coming from the subwoofer also? please keep in mind everyting is crossed over at exactly 52 Hz.

does anyone ever use their EQ to play with subwoofer frequencies? or is it uncommon to ever have to?

Want more mid bass ? Raise your x-over up to 80 hz and allow your sub to play those frequencies it was designed to , from 80 hz and down. Those Infinitys are NOT capable of doing a good job of playing down to 52 hz and sound good doing it. The very fact that you're crossing so low , and still lack mid bass , speaks of that.

Next , boost frequencies from 100 to 400 , and you will find the mid bass you've been missing , as well as your particular set up is capable of playing mid bass. Look closest from 100 to 200 hz to help your problems.

PS ; 60hz is NOT a mid bass freq , but a subwoofer freq .... and since you are crossing over at 52 hz , it is not being played well by those Infinitys.

Also .... I would cross the Infinitys over with a 12 or 18 db / octave x-over slope , and not 24. That's awful steep for quality integration with your sub , considering you're looking for some more mid bass ....

if i raise the crossover point i sacrifice a deal of imaging. when i play the components by themselves (no sub) they sound great.,. midbass is good. but when i let my sub play with them the sub seems to kinda drown out the midbass.. thats why i ask. i like the xover point where it is.. ive had it at 80 before and then i went lower.. nowim at 52 and have the best imaging ive got yet. i dont like the sub playing up to 80hz.

Ok .... Then boost the 60 to 100 hz freq's , but your Infinitys are going to crap on your sound trying to play that low. They will break up. The reason your sub killed your mid bass , is because your sub was up too high, in a less than approiate enclosure , or incorrectly EQ'd.

G'luck

Actually , after thinking about it , I realized you have some incorrect thinking about sub integration..... A well integrated sub has been proven many times to actually improve imaging instead of hurting it. It often opens up the sound of your other speakers and lets them show MORE spacial clues that help with soundstage/imaging .....

Chances are , you had too much low freq boost around 50 hz ...... This will REALLY muddy up your sound in the mid bass.

HTH

60-80Hz is somewhat classified as midbass. That's what your mids SHOULD be playing. Subs should be playing everything down.

my bass is not muddy at all. i dont have any frequencies boosted from 20-90. and when i boost 60hz about 3db it isnt very muddy.. just a LITTLE. so thats a no no. oh well ive got it set sounding good. im just really piccy and trying to picc out the littlest details..

If your sub is too loud with higher crossover points, why not try to adjust the gain on the sub amp to get it to blend better with your mids?

 

[noob with an RS 10+ year member]

its not too loud with higher xover points.. i just dont like the effect it has on my music. it also sacrifices the imaging from my components up from doing so.

I give up trying to help you ...... You asked a question , but don't like the answers ..... good luck with it.

Leave the sub crossed over at 52 hz... Then highpass the components at something a bit higher and with a less steep of a slope. After that you can boost the 100hz area a little and it should be good...

He already has weak midbass ..... Creating this gap in the frequencies will only hurt his attempt at better midbass.

Bottom line is this : He either needs a fabulous set of components that can play well down that low , or he needs to cross his sub over high enough to fill in the frequencies that will support stronger mid bass.

He's wanting his 6.5" drivers to give him a strong mid bass presentation down to 52 hz without crapping out ..... Dont we all !!! There is a few that will do fair that low , but expect to pay a LOT of money for them, also hope you have SEVERAL layers of Dynamat Extreme on the doors ......

This is where really good SQ subs crossed at 80 or so , come into play...... But he doesn't like that. Chances are , he didn'thave the sub properly set up in a proper enclosure , phased correctly with the front stage , with the levels set correctly , ect , ect , or he WOULD have been able to get a near seamless transition to his front stage without imaging issues.

If he gets a good tight sub , in a small sealed enclosure that's built really solid , and crosses it over around 70 to 80 with his sub x-over set at 24 db per octave and hid front stage x-over set at 12 db per octave ...... Then gets the levels correct and the phase switched right , he can accomplish what he wants.

He does NOT have an EQ issue , and EQ'ing is not going to solve his problem. He has an incorrect set up issue , considering the brand of front stage he is using ..... Trying to but a band aid on a gaping chest wound if you will....

I know , I've seen this MANY times before.

Let me put this respectful , but straight up :

#1 - Those Infinity Kappas are simply not good enough in the midbass region to give you the full midbass you want down to 52 hz ..... few speakers are.

#2 - A PROPER designed and set up sub will NOT hurt your front stage sound , only help it.

Accept these basic truths , and you'll be able to proceed with getting your system sounding better.

G'luck
