@@JacobViral2 ok thank you. I think I just need to add more volts to my system for more power. I'm only using prolly about 40% if that on my amp. I'm runnin all factory units right now. 2k is my max at the moment

If you have issues with overheating of your amp and you dont want RF interference from a cooling fan, try putting rubber spacers on your mounting screws between amp and mounting surface. It will keep the amp away from surface allowing heat to dissipate all of the way around the amp. Mounting surface could insulate the bottom of the amp holding in heat and possibly damaging amp components.

Am kofi from Ghana , you have been very helpful with the subsonic setting,now my system sounds better than the first time 👍

Use gain to adjust to keep your speakers from bottoming and keep subsonic off for 12s and larger. Turning that subsonic dial clockwise at all makes you lose low end output period. Subs are mostly meant to play low unless you’re using 8s or 10s. Then I could see turning it up a hair. Never had a problem in 35 years this way. Now, the low pass filter “features” the number it’s set at with more volume versus subsonic. Subsonic just cuts off below where it’s set at. But a slight roll off starts higher than where it’s set. Hope this helps. Oh, and Bass boost shouldn’t even be on amps period. Keep it off.

Thanks for the video. Love how you are using the sound deadening for your vehicle. Better carpet is also a way to get sound deadening in your car from the cheap OEM stuff in most cars. You can also add padding under the carpet, just make sure to get the stuff that is "fireproof"! Though it can be a bit pricey works great.

Very useful information,I need more learning on this but ,I do have a ear for my adjusting however to know the correct way is always the best way.✌🏾Thanks I will be watching this again when I retune my amps.

Dude thanks for making this video. I been trying to explain to sooooo many people how much this matters and they act like since they can’t hear it do anything that it doesn’t mean matter and since most music isn’t playing anything that low then the sub or amp won’t still try to play those hz

i never thought subsonic would affect the high frequencies like that. learning every day.

"Only two 15's" yeah, no big deal. Lol

It is a sweep you need to play music and adjust the subsonic because if the sub is moving to much in relation the enclosure it would disrupt the air in the port reducing higher tone output. Some people dont know that it is the air in the port that vibrates and make sound. Especially if the sound have low and high tone.

Exactly.... I run 12s and subsonic takes a lot away from the good, rich deep, bass im pushing now and I have a small system but the sound quality is good and I didn't spend an arm & leg on equipment, plus I am only running 1200 Watts, so no need for an extra battery or upgraded aftermarket parts either, just make sure you run it correctly and you shouldn't have much of a problem with it.

At about a half an octave below enclosure tuning, subwoofer output will begin to diminish. At just below tuning, the driver will begin to "unload", and excursion will increase. I personally recommend setting subsonic about one quarter of an octave to one half an octave below enclosure tuning. This will vary, depending on the slope of the subsonic filter being used. I am using a DSP which affords different slopes, or dB per octave. The steeper the slope, the lower you can set it without damaging your driver. Always remember that the lower in frequency you play, the driver will want to naturally move farther anyway. When making your adjustments, start out high, then work your way down, observing excursion and listening for mechanical distress. Cheers dude!

Exactly this. Thank you. So much bad information on here.

This great if you have a variable setting on your amp. Mine is 25hz or off! I have a sundown audio zv5-18 that plays down to 20 hz well.

A lot of great info there! You got just about everything right. The subsonic filter comes into play ONLY if the amp receives frequencies that are below the lowest tone the sub can produce at 3db down. AND, the filter only comes into play IF there ARE frequencies present in the infrasonic range. Using a good signal generator should not produce any frequency other than what it is set to. If harmonics are being generated in the signal chain, then you have a problem. Another thing, what is the slope attenuation of that HPF (subsonic filter)? I bet it's no higher than 6db/oct. So, as you set the level up near your fundamental tone, it may be already sucking the level down! You want to be anal about this? Get an "O" scope and look at the waveform levels while you play with the filter. A subsonic filter shows it's colors when playing a warped LP on a home stereo. The subsonic cone movement in the woofer can be crazy bad!

Welcome and glad to help Daniel 👍

Very good information videos of SPL and adjustment

The actual best setting for the subsonic/infrasonic filter is the one that limits ultra low frequency excursion to prevent damage. A side effect of this is that you are now drawing less current when playing those ultra low frequencies meaning less voltage drop and possibly more average power in your supply. This may lead to slightly higher dBSPL numbers but is unlikely to be noticed by most. I would recommend finding the frequency where the sub begins to unload and have crazy xmax and slowly turn up the volume until the sub begins to reach close to xmax but there's still power you can add. Then adjust the infrasonic/subsonic filter until the xmax drops then repeat with slightly more power until you reach max power and the sub is no longer exceeding xmax below tuning at whatever frequency was ideal to pick for your setup. If for sub for example is tuned to 35Hz and it will begin to exceed xmax at lets say 25Hz then you should probably have a filter setting around 25hz or so to cut off that low bass a bit so it doesn't damage your sub. It will also put less power into the coil at low frequencies so maybe you can get a touch more power in the higher frequencies that the sub can play leading to more dB.

thanks dude.. This applies to all enclosures? Even 6th orders?

Jacob makes a solid point, and the demonstration of it is nice to see. I feel that the emphasis should be placed on what we did not get to see: he set the gain after the process we saw, I can't help but think that it would have been a stronger finish to test the final result in the same way for total emphasis besides the drop in decibels post procedure. Many simpletons will take away from the clip that you can use the subsonic to get a bit more db but just don't keep it there. I have been one of them in my checkered past🙃

Turn the dial on the subsonic counter clockwise until you can hear that sweet spot. You'll end up with the subsonic set lower than your box tuning.

Most subsonic filters are just a high pass filter and on many amps there's no mention of the slope. If they had a super steep slope they'd be great for precision limiting, but I prefer leaving them off and controlling low frequency extension at the deck. If your setup is loudest at 45-50hz for spl purposes, a Subsonic filter is the quick way to chop out the frequencies you don't want sucking your power away. For SQ, leaving Subsonic filters off is best IMO.

Why not set the subsonic filter CORRECTLY instead of just guessing on the analog knob? Many amps are not accurate on their markings and "eyeballing" it is totally wrong. First set your gain correctly, then set your low pass filter. To properly set yoir subsonic filter, do the following: 1. Turn subsonic filter OFF by setting it all the way to the left at the lowest setting. 2. Play sine wave of desired subsonic setting, for example 25hz. 3. Using a multimeter take note of your voltage you have from your test tone. 4. Multiply your voltage by .707. So if I saw 40 volts I would multiply it by. 707 giving me 28.28 volts. 5. Turn up subsonic filter until you reach this voltage, subsonic is set.

Why 28.28?

@crx122

4 жыл бұрын

@@brian3364 28.28 just happened to be what the voltage would be in the example I gave. You pick a subsonic setting you are aiming for (25 hz is usually a safe bet if you want me to make it easy for you) and then find your baseline voltage reading you have with the subsonic filter turned all the way to the lowest setting. So I gave an example of 40 volts as a baseline reading, you'd play your 25hz test tone, or whatever frequency you are wanting your subsonic filter set to. With the subsonic filter set at the lowest setting (turned all the way to the left) you get your baseline reading. If for example you saw 40 volts then you would multiply that number by .707 giving you 28.28 volts in our example here. Turn the subsonic filter up until you reach that voltage and you are all set. It is quick and easy! Just make sure your subwoofer is disconnected while doing this! You don't want to potentially damage it blasting ultra low frequencies through it while you are setting the filter initially. Alot of people like to set their subsonic to 5hz below their box tuning, I personally have always just used 25hz and it works perfect. Your low pass filter can also be set using the same method of getting baseline voltage and multiplying by .707 as well, using an appropriate test tone. Only difference is the knob would be turned all the way to the right to start.

I hear too many people's systems that don't understand this concept. Yeah it might hit hard but this next hit right after that sounds like a fart. Without properly adjusting the subsonic the speaker cannot return to original position to throw again in time for the next hit. I also am like you in the respect that I would like to hear not just the base but the instruments and the vocals setting the subsonic helps tremendously. I also have tweeters and not the kind that comment on stuff LOL

Bro I feel you and appreciate your video and your intention. Totally respect it. Just keep in mind that you cant use a cell phone and accurately get a proper SPL reading. You have to use a legit SPL meter. Especially since your tests show +/- 1.5 db difference could be as simple as the the app SPL error range. But I agree with you as far as protecting the Sub you should definitely want to have your subsonic set accordingly to the subwoofer specs.

My ported side is tuned to 56 hz it's a external octoport I would love to get the most output out of my 8s that I have in there now thanks for the reply Jacob!

Is the spl meter a downloaded app on your phone? Is it accurate?

Requires a db device meter. Ssa studio app but only works with meter

so if tune to 30 my subsonic should be round 20-22hz ?

@Widowmaker2828

According to Jacob it would be 22.5. Multiply 30 x .25 and subtract the answer from 30.

What C Smith said is correct. Half an octave below tuning is a good guideance range to tune your subsonic to.

I look at my subs manufacturers and says between 25 to 30 for subsonic. I have skar evl 12s

Hi, my subwoofer making whistling sound at around 25-30hz, what could be the problem? Thanks.

Never heard of that problem weird. Only high volume levels? Could be clipping if so.

@@JacobViral2 Not always, I mean it does that on low frecuency only I noticed around 25hz and up sound like air leaking but everything is well glued. Sounds like that whistling/rattling sound coming from sub. But when you listen on max vol. inside of car doesn't sound like distorted, like normal.

My box is tuned to 23hz and my subsonic is 17-50hz so can i leave it at 17hz?

Yep sounds right

Half octave is 45*(√0.5)

Anyone who is worried about an SPL score probably already knows what subsonic is and how to set it. People who just have an amp and sub in the trunk of their everyday ride will probably need to know what it is and whats the best way to set it for good sound quality. Just saying.

My four channel have a subsonic filter. I use the amp only for mids. Should I use the subsonic filter

Your high pass should already eliminate any frequencies that a subsonic filter would effect. Your high pass should be set above any frequencies that your subs would be playing. Generally your subs should go no higher than 100hz and your front or rear stage wouldn't go any lower than 100 hz. In systems with a three speaker full active front stage you might have an 8 or 10" mid bass driver go down to 80hz but your subs should be set for a low pass under 80hz so that they don't cancel each other out. The subsonic filter will almost always end at 50hz so your interior speakers connected to your 4ch should already be completely crossed over and silent down at 50hz. If it makes you feel better there should be no harm in you turning your subsonic filter all the way up on your interiors but it wouldn't or shouldn't effect anything.

This was probably the worst explanation of the use for a subsonic filter I've ever heard. Basically a subsonic filter is used to increase the efficiency of the bandwidth your trying to play on your subwoofers. If your amp is trying to reproduce sounds that are very low like 20-30hz it takes rail voltage to do that. You will want your amp to have that voltage to put towards the frequencies your trying to reproduce 30-80hz (in most cases). It's been around since at least the 1970's but was used in home audio to protect damage to your speakers that had a difficult time reproducing bass below 30hz but also has the benefit of making your amplifier more efficient in driving your speakers in the range you want. This results in an audibly tighter bass reproduction.

I get so much speaker flex my mirrors shake. The speaker can't do rms power if I don't have the the subsonice filter on with the hpf at 80hz, it does 125hz perfect with the subsonice filter off

If the subsonic tuned to high could it blow the speakers or get it to skip beats?

Subsonic will cut off lower frequencies with a grater dB reduction so if it’s too higher your losing output.

I was always told subsonic was for ported enclosures only. Do I tune this for my sealed box as well?
