Hey guys,


I am curious to know how everyone has their system setup in regards to frequencies (cut offs etc) as you see most members stating their frequency range's for most of their components (tweeters comes to mind) in various threads.


I was thinking for structure, maybe something along the lines of stating your system components and the frequency range you have 'allocated' for that part of the system, as well as why you have it at that certain range (maybe due to driver limitations etc)


I would get the ball rolling but I haven't got a system installed



Cheers,

Jas.

see sig

boston: up to 50-something hz
oz's: 63hz - 2.5khz
morel's: 3.2khz+

why? because it sounds good like this

i have set my 3 ways up 2 different ways

having the tweeter just around or above the upper voice freq 5khz and up
midrange 800hz to 5khz, for trying to get all the vocals comming from those drivers.
midbass-upto 800hz

the other way is to run it like a 2 way
tweet- playing as low as it possibly can 2khz
midrange- just being used to play a small amount the freq range 1000hz-2000hz
midbass-upto 1000hz

Currently:
Focal 33KX LP 56Hz/18dB
Dyn MW160 HP 71/18dB LP 560Hz/18dB
Dyn MD140/2 HP 710/18dB LP 3k2/12dB
Morel MT23 HP 4k5/18dB

This will change considerably by next round

This is changing this weekend because of my new tweeters (yeah!) but....

Dyn MD130 5Khz 24/oct
Dyn MD140 300Hz 36/oct 5kHz 24/oct
Dyn MW160 80Hz 24/oct 300Hz 24/oct
JBL 2268HPL 100Hz 36/oct

subs LP @ 50Hz ish @24dB/octave
the rest HP @ 65Hz ish @24dB/octave and let dynaudio worry about the rest..yes I use passivses


can't be more specific as never scoped it, to see whats going on

Woofers - 20 - 63Hz @ 18dB
Mids - 63 - 2500Hz @ 18dB
Tweets - 2500 - infinity @ 18dB

Woofers :- 63Hz 24dB Low Pass
Mids :- 63Hz 24dB High Pass <-> 3150Hz 12dB Low Pass
Tweeters :- 3150Hz 12dB High Pass

I might try back down around 1250Hz mid-tweet when I get my system running again.

Sub 63Hz 24db Low Pass (active)
Midbass 63Hz 12db High Pass - 200hz 6db Low Pass (active)
Mid 500hz 6db High Pass - 5500hz 12db Low Pass (passive)
Tweeter 6000hz 6db High Pass (passive)

You may think I have a massive hole in my lower midrange with one cross point being 200hz and then the mid picking up at 500hz but my reasoning for this is that the DLS UR6 drivers have an incredibly strong and bright lower midrange and theres a huge peak around that area, so rather then waste eq bands trying to EQ it out I've chosen a more shallow slope using it to help eq out the peak. It seems to work quite well and give decent performance and I'm still using some eq to bring that area down so it gives you an idea of the size of response rise I'm trying to control.

not going to answer this just yet as it all just got installed and I'm still mucking around...but this is a great thread, especially with people indicating why they use a certain setup, and whether or not it works well.

otherwise, we just get a 63>2.5k, or 63>300>5k at 12 or 24db slope type answer.

i have my crossovers set up 2 different ways..

Street (general cruising):
sub - 80Hz LP
midbass - 80Hz HP / 250Hz LP (bandpass)
mid/tweet - 250Hz HP (then midrange/tweeter x-over thru focal passive)

SQ mode (in comps):
sub - 63Hz lp
midbass - 63Hz hp / 315Hz lp (bandpass)
mid/tweet - 315Hz hp (then midrange/tweeter x-over thru focal passive)

why the changes Damo?

Looks to me like he enjoys some volume...!!

i dont have much of a system just a sub and a 2 way component but

sub 63hz / 18db or 12db cant remember
component 80hz /12db

but anyway would i be missing some tones with a gap like that even though my slope is only 12db not 18db or 24db?

For dance and more upbeat music
Sub- 100hz@24db
Mids- hp100hz@18-24db and Lp 3.2khz@24db
Tweets- 4khz@18db

And for rock and more classic music
Sub- 80hz@24db
Mids- hp80hz@18db and Lp 2.5khz@24db
Tweets- 3.2khz@24db


this is constantly changing i dont think it will ever stop!

Most cars tend to have a boost around 80Hz naturally. By leaving a gap, I think you'll find that the system is more linear.

no sub at the moment

mids from about 'yay'
and tweeters about 'yay'


sounds good too

^ very interesting fudd. I like your choices.

anywho...

Rainbow Profi 10" Sub @ 71Hz 30db\
Sinfoni 6.5" Mids @ 71Hz 24db\ and 2k5Hz 24db\
Sinfoni 1" Tweet @ 2k5Hz 24db\

Sounds great for this car, tweets are low as they are a-pillar mounted and bring the stage up above the dash nicely. This is what I ran at nationals last year and the judges seem to like it too, came equal second, 1 point off first in AMST.
And for daily turn the sub up maybe +2 or +4 depending on the cd.

Ant

Boston G512: LP 63hz @ 24db
Alpine Type X MB: HP 63hz @ 24db - LP 315hz @ 18db
Alpine 4": HP 315hz @ 18db - LP ~2.5khz @ 12db
Total Recoil 1": HP ~2.7khz @ 12db

Mine is:

CD2MH 1000hz up

X65 80hz to 1000hz

12's" 80hz and down

All with 24db slopes. Because I have steep slopes I can get away with this, if I was only using 12db, I would need to run the horns from about 1.2->

Sounds dang good to me, as for comp use?? Dunno.

tweeter/4k -18db slope
midrange/280-4k -18db slopes
midbass/50-315 -18db slopes
sub/50 down-18db slope

sounds good

my whole system is tuned for yay lol

TW 4K/30
MID 4K/24
400/24
Low 400/24
50/24

Sub 50/30


It varied from car to car so those number doesn't mean anything to me. the quality of your install will tell which Hz you will cut your frq off and by how steep. as a rules of thumb, learn to read the spec sheet of your speakers. That will tell you much more than I could ever tell.

A question to the gents running BIG slopes on the mid-tweet merge, where abouts are your mids lcoated?

I have been playing around with 24dB mid-tweet merges, but find it slightly lacking. I am crossing over at 1.6k though, so possibly it's due to the low freq I'm using.

Following up on this. Last night I did some testing with differing slopes and frequencies and it seems that with 12-12 and 24-24 I was still getting a slight dip at the crossover frequency.

Am I correct in saying that a 12-12/slope with speakers wired electrically in phase I could rid the 'dip' by putting them eletrically out of phase? Or in turn I could have a 24-12 or vice versa slope to try and remove the dip without requiring EQ?

Thats partly the reason Matt.. but a good one... and yes, i do enjoy volume.. especially when you got 1400wrms at your disposal for front stage duties..

the main reason for the shift in crossovers is longetivity..
i run safer crossover settings for daily use... and more 'accurate' settings for comp.. the midbass rolls off ~300Hz.. and 315 is fine for comps, but not daily..
dont really wanna blow them so yeah.. and playing the midbass down lower also works with blending the midbass & sub better..

in future, the new setup will be left at the "street" setting..

At times i thought i had some good sounds running 24 db slopes on the Lp on drivers and using 12db slopes on the hp.
what are u using for your rta testing?i need to do some myself but havent got one .

Subs @ ard 85hz for daily use
Midbass @ 85 - 1 Khz
Horns handle the rest @ 1Khz to 20khz

thinking of getting a pair of tweets to do the 17.5 upwards as horns are dippin at that point

heheehehe
Sub 63Hz 24dB
midbass 63Hz 24dB / 630Hz 6dB
midrange 1kHz 6dB / 8kHz 6dB
tweeter 4.5 kHz 12dB

might change again *Shrugs*

I don't run a system right now, but my previous one was as follows:

Scanspeak D3004-6600 AirCirc: > 2.5khz @ 18dB/oct
Scanspeak 7" Revelator: 160hz @ 18dB/oct - 2.5khz @ 18dB/oct
Peerless 12" XXLS: < 160hz @ 18dB/oct

I was using Eclipse E-iserv for my 'RTA' (term used loosely), it was the best I had access to. I'd do approx. 3-4 test of each set-up and then jump on the web and let it do it's thing and compare the results, more often then not, they were exactly the same.

Should have an ECM8000 and UB802 on it's way to me soon so I can get some 'real' results however
