Tuning splits

[NightKids]

Hi I currently have some Morel Maximo splits hooked up to a 4 channel Alpine amp. Rare fill is perfect doesn't need to be touched. I was playing around with the gains for the splits and it doesn't have any filters on at the moment.

My tweeters are a little sharp when the volume is up. The vocals sting the ears a bit. At the same time the vocals seems a ill recessed. Does anyone know what tuning I should be focusing on to correct these problems?

I'd firstly check what db the crossovers are on to split the sound to the tweeters
Might as simple as changing that.
At the moment I got my components on about 80hz with my amp set to high pass

Hope that helps

If u want the filter on the crossover to be the primary use, then set your amp filters to Normal, set freq to 160hz.

if your crossover has different frequency choices, then set the mid to. 120-180hz and the High to 12-17hz.

Then finer tune the high/mid filters on the HU for the listening ears.

Once satisfied, then tune your gains on the amp them the gains on the HU.

At the end of the day, its up to u how loud ad linear you want your setup to be. Just tune it to the sound that your ears will satisfy.

I don't think the crossovers on the Morel Maximos can be tuned.

So what settings do you recommend for the amp? Or is it always going to bypass the settings on the amp and go off the crossovers?

I just found one of the manuals for the Morel Maximos.

So you're running them passive?

Normally the crossovers will have a 'jumper' or a switch built into them for attenuation of the tweeters.

If they seem too 'bright' or harsh, then you can attenuate them to pull the level down a little. That's the first thing I'd be looking at.

Iirc the maximos dont have tweeter attenuation.

Yeah there doesn't seem to be anything on the crossovers. So what are some ways to tune this down?

As i mentioned earlier,

if your running these splits off the amp - set the AMP to NORMAL rather than HIGH. then maybe play around with the crossover on the AMP from 120-180hz. Then Finer tune from the HU.

Pioneer systems generally has the Frequency tuning which allows you to tune LOW / MID / HIGH.( depends on which model types)

Basic units will have the below;

Custom1 Sound settings: set the Equalizer curve to:
Set LOW to: 50-60hz +2db
Set MID to: 500hz +0db
Set HIGH to: 10-15hz +4db (play around with this to suit your hearing level)

TURN ON HPF to: 63-125hz

Sub W.1 = Turn ON
Sub W.2 = Set your Subwoofer Freq to: 50hz or lower. + 2db

LOUD(NESS): Set this to HIGH.

IF your tweeter is still too high and pitchy, then try adding an inline capacitor anywhere from 4700 - 8000uf to the Tweeter line after the crossover to lower the Hz if the AMP or HU cannot do the job. - Search up in google or ask Jaycar on a recommended capacitor type to lower the Freq.

Note* adding a capacitor on the tweeter line will override the crossover pre-tuned onboard capacitor.

this would be the only DIY you would have to do.

example here:



Example.
8 uF = 8000 uf.
4.3uF = 4300 uf.

let us know how u go

None of that will work, if anything, itll make it worse, especially this part

Set HIGH to: 10-15hz +4db (play around with this to suit your hearing level)

What NightKids is after is the opposite of what youre suggesting. He wants the tweeters turned down because its too harsh, but by lifting the HIGH up its only going to become louder and even more harsh.

As for the high pass filter, and sub settings, this isnt going to do anything to lower the tweeters.

About all that you suggested that would work is adding an inline capacitor.

However, this isnt needed. That model of headunit has a 5 band Graphic EQ, (which is more indepth that just high/med/low) so all that he needs to do is simply adjust the 2 top end bands down by a couple of db until he finds it sounding nicer.

u have no idea mate.

Placing a an inline capacitor (correct uF/volt) after the passive cross over will override the freq set on the crossover unit.

Go ad get a oscilloscope ad measure the waves of the freq output.

What NightKids is after is the opposite of what youre suggesting. He wants the tweeters turned down because its too harsh, but by lifting the HIGH up its only going to become louder and even more harsh.

What im suggesting is a full tune not just some dodgy turn down the High pass and away u go.

Hence why this is an example tune that he can try out.

Gving him the option that splits system is not just plug and play away u go but requires finer tuning to get fidelity results.

As for the high pass filter, and sub settings, this isnt going to do anything to lower the tweeters.

If u are familiar with pioneer units, the HPF settngs must be tuned to obtain sound output quality. It allows finer tuning to the equalizer curves and the sub tuning.

U just dont assume lowering the high pass filter will solve everything but instead will give u a monotone sound.

U have to tune from high - mid - low order.

About all that you suggested that would work is adding an inline capacitor.

This is what i suggested. And u just contradicted your own statement above by saying it will not work or will make it worse.

However, this isnt needed. That model of headunit has a 5 band Graphic EQ, (which is more indepth that just high/med/low) so all that he needs to do is simply adjust the 2 top end bands down by a couple of db until he finds it sounding nicer.

And again this is the equalizer curve im talking about.

What i suggested on the frequency and the boost db levels above will provide a nice linear output. But again this is an example. Why i said play around with these settngs that will suit your hearing levels/needs.

U are correct. If the high freq has lessen due to the other tuning capabilities then its not needed.

Otherwise inline capacitor is the way to go. Or buy another passive cross over unit.

Iirc the maximos dont have tweeter attenuation.

you are correct sir.

as said by trism:
