Crossover Frequencies

[Dunno]

Hi Bros,

 

Just wanna find out what are the crossover frequencies you guys use for

 

1. HPF on front component speakers (passive crossover)

2. HPF on rear coaxials

3. LPF on Subwoofer

 

I want to try out different sets of combinations to hear the effects. Still learning how to tune my setup

Hi Bro,

Different setups use slightly different settings and also personal preferences come into play.

From time to time, this topic was brought up. You can either start check this thread:

I know the range of recommended frequencies for HPF and LPF. I'm just asking what is the frequencies the bros here use.

This is my tuning setup

Hi Bro,

It's gonna be hard to share this info because most of us, if not all of us are running active and our xover frequencies are for the tweeters/mids/sub do we have HPF(Tweeter), HPF and LPF(Mids), LPF(Sub).

 

What you are using a basically just Front/Rear/Sub so your crossover frequencies will be totally different from ours.

You can only set HPF for Front, HPF for Rear and LPF for Sub. So our settings will not work on yours because you can't set the mids individually from the tweeters.

 

I dun think there's anyone here using rear coaxials, most just have front speakers and no rear because in an SQ setup, the rear speakers just get in the way of the front stage.

In any case, in your instance, the HPF for both the front and the rear should be slighylt higher or the same and the minimum recommendation for the speakers.

For example, if your front speakers specs are 50hz-20khz, then your HPF should be 50hz or 63hz....just a rough guide...need to consider brand,damping, car size, woofer size/power etc...play around with your ears to get the best setting.

Try...

 

HFP Front: 63Hz

HPF Rear: 80Hz (keep to real low level so it does not affect front stage)

LPF Sub: 63Hz (If got subsonic filter, apply at 25Hz-20Hz)

I am not sure if you can still apply your own set of crossover values on the amplifiers since you are still using the passive crossover. Passive crossover has crossover point set by the manufacturer already, manipulating it may not give you the effect you thought you should be getting.

 

What I think is

 

- Front component HPF can range from 50Hz to 80Hz depending on how well your midbass can handle the lower compartments.

- Rear Coaxials HPF can range from 100Hz to 200Hz depends on what soundstage you want to achieve.

- Subwoofer LPF to match that of your front component HPF, this is the handshaking point between your subwoofer and the front component. A well-tuned system will leave you the impression that the subwoofer in at your front compartment rather than from your car boot.

 

The more catchy portion is the handshake between the front component HPF and that of the subwoofer LPF. Too much or too little will make your car boomy or dislocated lower mid and sub ranges.

 

Enjoy tuning.

Hi Bro,

Perhaps you may find something in this passive setup of my previous setup before I upgraded to active.

 

At that time, I was running front components, rear stock coaxial speakers for rear fill-in and a subwoofer. This was the previous passive tuning that I was happy with for sometime before I upgraded to active.

Thanks for all the advises
