Are you saying that if you turn the subsonic off or as low as it can go I get more output from my amp?

[@JacobViral2]

@@keehud333 no, that will just offset less cutout point on the lower frequencies to the sub to have more power at a lower volume/gain level is all. Amp only puts out what it can do with the proper tune

[@keehud333]

@@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

[@TheDoozie43]

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.

[@houseburner1188]

It depends on the enclosure and sub. Subsonic protects the sub from over excursion at frequencies below the enclosures capability.

@@MarquiseBeatz__ sounds like either a weak ground or your amp is getting hot from lack of air flow.

[@prestondallas4035]

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.

Being as I have recently as January gotten back in the car audio world I have so much to learn and I get really confused when it starts getting into these types of topic areas. Basically learning to have everything matched from Head Unit back to amps and all in between. Learning slowly, but learning none the less!!! Thank you for another insightful video!!!

[@SilentShadow-ss5xp]

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.

[@skywalker859]

[@LividLeon]

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.

[@prestondallas4035]

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

[@filibertofonseca8083]

At the end of the day we want to be louder but what i got from this is that its mostlikely best to set the subsonic before i set the gain because changing the subsonic later would change the output voltage.

[@anglerandy5736]

He didn't do this. I have a 32 hz ported and a dayton max x 12 28hz what do I set my subsonic to, 31.5?

[@filibertofonseca8083]

@@anglerandy573628hz is subs resonance fs. subs will play below the fs and also box frequency by around 6 to 8 hz. You need to be able to tune by ear. No vehicle and system are the same so I can't just say yeah set it to a certain frequency without hearing it. Start with the subsonic set to 30 hz, You'll need to turn up the volume where you think it's kind of loud but still sound clean. 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. Also Maybe this will help , the lpf (low pas filter) filters out the highs to the sub and the subsonic filter's out the lows.

[@anglerandy5736]

Thank you for the advice.

[@crx122]

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.

[@angelvip2474]

Dennis Randolph or I just pull out my SMD CC1. 😃

[@crx122]

@@angelvip2474 That is another option yes, but my point being was that there are very easy methods to correctly set the subsonic filter without any expensive tools. Not everyone owns a DD1, and they are quite expensive especially if someone will rarely use it. A multimeter can be purchased for 5 bucks at harbor freight and does the job fine as well.

[@angelvip2474]

Dennis Randolph I absolutely agree with you bro. It is also good to know the procedures ,the how and why it works not just winging it. You did a great job explaining the procedures. I was just being a lil smart ass😂👍👍

[@brian3364]

Why 28.28?

[@crx122]

@@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.

[@notyobiz6207]

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

[@RodofAllTrades]

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!

[@poncethegayboi]

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

[@johannjohann6523]

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.

[@curtchase3730]

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!

[@drvictoria07]

Is the subsonic the same as a high pass filter? I'm asking because I want to use multiple full range monoblock amplifiers to power my door speakers 🔊

[@rhurtadorh32]

You can always leave it at half way and you wont have any issues at all.

[@2slofouru]

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.

On a ported box you set it near port tuning. Keeps the cone under control as the box will not below port tuning(unloadeding/free air). this can be found by doing a frequency sweep and seeing where the cone movement is the least that’s right around tuning that’s right around where you want your Hipas set. If you are not using enough power to exceed the drivers x max its not necessary but still recommend as more power will be utilized in the drivers usable range. On sealed enclosures, In vehicles with a high transfer function u can actually have too much low hz content and can use this to eq it out.

I need help, I got a phoenix gold rx 2 500 amp with power bass 12”subs, first time getting a sub and amp, and I want my bass to actually hit. I keep seeing videos, yeah they explain the frequencies, gain, sound, etc. but what I’m looking for when tuning is what do I need to turn and adjust for more BASS, idc about the sound, distortion, loudness, etc, my main goal is BASS. Do I need to upgrade my amp to get more bass? Play with the knobs? Or should I get new subs and amp??

[@JacobViral2]

lots of variables from your box, port tuning, music played, electrical battery/alt power supplied, amp rms rating, subs etc. I would say you need to consider all these and go from there. Feel free to message me on instagram/facebook jacob viral and I could give you guideance

Do I need to use the subsonic filter if I'm using a dsp to set the hpf? My subwoofer specs are 25-250hz, so I set the hpf at 25hz and no slope in the dsp. Also, what is the best way to set gain and lpf for a subwoofer?

Yes and this video helps for lpf kzbin.info/www/bejne/rH3Pg519mNCafsk ; thanks for watching and subscribing

How do I know what a box is tuned to? This is the box I'm using Rockville REC97 Dual 12" Ported SUV Subwoofer Sub Box Enclosure - Behind 3rd Row

[@TheBudugravy]

Also you seem very knowledgeable about car audio. If you don't mind me asking. I have 2 12 inch skar svr's. The recommended enclosure size is 1.75 cubic ft each and the box i have is 1.25 each. How bad will this effect the subs? Im limited on space since i have 3rd row. I am running a hifoncs 1750 class d amp. So the is there for them just don't want to burn my subs up. Not necessarily trying to get into competitions or anything. Any input or recommendations you could give me?

[@JacobViral2]

@@TheBudugravy You’ll be completely fine just you may be tuned a little higher and the subs won’t plays the lows as well plus needs more power on the to really get the output they can do when smaller box then recommended but overall it’s just a tighter punchier box probably.

[@TheBudugravy]

@@JacobViral2 thank you so much. I was worried it would damage them honestly. They are new and sound good. They do have a tighter bass and don't get super low. But also not trying to be in competitions with them so they work. You are saying I should add more power to them? I would but there already distortion some times. Could that be because my amp isn't set how its supposed to be or maybe underpowered? I really do appreciate your help man!

[@JacobViral2]

You could be maxing your amp out and not giving the subs the desired power being after voltage drop and rise maybe 400-500 per sub max my guess. It’s always good to have a bigger amp and not max the amp output out.

I have two Skar Audio 12s ported with a 1200 rms Skar amp box is packed for 40 hrz what should I set my gain and subsonic to

[@murrayshekelberg9754]

i think you would want it set to about 30hz if you're tuned to 40(half of 40=20 half of that is 10, subtract that 10 from the original 40 that you're tuned to).

[@naloshneeshanithamoodley2344]

I did not understand your calculation, half of half, 13 hertz is what you said, but you set it to 35 hertz? Please help

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

[@brentb5303]

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.

[@brentb5303]

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.

[@ronaldomaynard4816]

@@brentb5303 my subsonic filter is 20 to 500hz. On my ampere 150.4. I have a pair of beyma 8's. 8cmv2 is the model. I have a pioneer 80prs and the hpf is set to 80hz. 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

[@randomtube8226]

It really depends on what you are wanting. For me I like getting the biggest amplifier possible, use one sub per amplifier. I turn my gain and bass boost all the way down. I have powerful enough alt, bat, and caps to maintain 15v at max volume.
