Don't buy a SUBWOOFER until you understand... Subwoofer Parts Explained!

A subwoofer is more than just a big speaker, there are several components that make up the subwoofer's anatomy and having an understanding of what they are and what they do will allow you to pick the perfect subwoofer for you for your next car audio system.
A special thanks to Rockford Fosgate for letting me borrow the cutaway subwoofer for this video! www.rockfordfosgate.com/

Good news guys! I just uploaded a NEW video showing how to build a “stack” style subwoofer enclosure. This “stack” technique allows you to create some very advanced subwoofer boxes. Check out the build here! kzbin.info/www/bejne/hZ2QeWN7d6qCa8U

[@dwightdonaldson7613]

Which voice coil is better...copper or aluminum

[@seansmith4440]

This is a great introduction video Mark. Can you do a VERY in depth video on what makes the best subwoofer? As in what type of material is the best for the surround? Megaroll? Ribbed like DD subs? What type of metal for the voice coil copper? Aluminum? Flat wound aluminum? 4 layer flat wound aluminum? Size of voice coil? 3",4" 10"?! How about spider material? Nomex? Conex? Kevlar? 4 layer? 8 layer? 26 layer?! Linear or progressive spider? Double spider like that Fosgate your showing? Triple spiders with 1 linear in between 2 progressives? Where does it end? Single magnet? Double, triple, quadruple?! So many questions. That would be a great video and get LOTS of views for sure. Thanks again Mark!

[@vincentcisneros9737]

Did a research paper about this in early 90's for my English class. Tech hasn't changed much. Innovation in the design has. Still believe less is more though. Long live old school!!!!

[@mark.4047]

vincent cisneros : most car woofers are a waste of time. 4 8" pro woofers slaughter these low sensativity power hogs.

[@ACommenterOnYouTube]

as they say, it not the size of the sub, its how you use it. I have a free-air 8 inch in my genesis coupe and people can't believe its a free air sub.. Bottom line is .. if the sub can handle 500W rms... give it at least that much or a bit more... Don't starve it !!

[@lm6036]

@@ACommenterOnKZbin Bullshit. Free air a sub will reach Xmax long before it reaches rated RMS limits. A 1000 Watt RMS sub will already hit peak excursion at less then 100 watts.

Wise man ,You're a great observer 👍

[@Anonymous-cu8eu]

Excellent video, it's awesome you showed the unique design features of that sub so that people can understand how a company can engineer different aspects of the woofer for better performance. Much more to subs (and speakers) than a big magnet and how many watts of power it can handle.

Mark you are amazing man! You remind me of my days fabricating aircraft parts from alum and working fiberglass components in all shapes and sizes up to and including removing wings from jets, deskinning them, complete teardown and rebuild of new parts. Those tools you have, man, they melt my heart man they create art!! You have a set of subs you put in the back of truck that made the sub box look like fox eyes or something, it was bad ass. I want those templates but didnt see them on your store? Keep up the superb work you are second to none

[@OriginalHooker]

I happen to have two Rockford Fosgate P3 12s so it's interesting to see exactly how they look/function. Nice video.

[@mrchubbyfella9421]

Jordan what kinda amp and do you like them?

[@OriginalHooker]

Right now I'm using the Rockford Fosgate Prime 1200-1. Works very well for these subs but eventually I'd like to have a T1500-1 bdcp. Their punch 1000-1 would be a good match as well.

[@sHoRtBuSseR]

Jordan the constant power amps aren't worth the money. just get the standard t1500

[@texmextu2]

I am Coast2coastLoud pioneer gm-d9601 works good too for half the price.. shop smart

[@youdoofus]

I have these exact P3 12"s also and am quite fond of them. There are of course FAR superior subs out there, but these have been serving me well over the last 3 years. Pushing them with a SoundQubed SQ2200.1 (the model without the words "sound" and "qubed" flanking the logo, and it hits HARD! The amp is only seeing 2 OHMs because i didnt know that a: its actually easier on the electrical system for certain amps at 1 ohm than 2 and b: didnt want to "push the amp too hard" at 1 ohm, which turns out to not be the case with certain amps either. Great subs for the price, but id definitely get sundowns in the event that i was shopping for subs again.

You need a subwoofer to get a car, so you can get a licence

[@NvTwist]

The surround also had the job of sealing & keeping the air pressure/vacuum separate from air outside the box yet still flexible enough to provide Xmax

[@tonyv33ee]

NvTwist are you speaking on this particular sub being talked about

[@VinnieVega76]

Nice video, many people don't understand speakers and how they work. One thing you forgot to mention is how the voice coil diameter affects the power capabilities of said woofer, as in a smaller voice coil will bottom out regardless of said power rating, RMS I'm talking about vs peak. A larger voice coil can take the same number of wraps as a smaller one, combined with a great suspension, spider, you can put way more power to it RMS or peak without the woofer bottoming out. Also a larger voice coil will cool off faster due to the diameter of the coil. I have a digital designs woofer with a 2.5 or 3 inch coil, and from my experience with pro audio where we used 4 inch VCs for a 15" sub vs a 2" coil for an example, Kenwood 12" 500 watt sub, I'll take my 2.5" coil 10" DD all day long, it has a fantastic spider, is made in the USA by top tier manufacturer's but looks like that fosgate has a 2 1/2 or 3" coil. Just saying that is a very important thing to know about your subs before you buy them. All in all, nice to show people who don't understand woofer basics instead of just saying I got these 500 watt subs that are awesome, but how much do you know about the sub before you buy it. Go made in USA always for a quality product like fosgate

[@ryanmoore9877]

Another great informational video Mark thanks. I did just support Fosgate again by buying 2 p1s4-10's. Can't wait to integrate and enjoy them! Maybe I spaced out and missed it while you were talking about the spiders but I thought I'd seen a Fosgate video explaining that their reason for having two on their larger more powerful subs was to also help control excursion etc, in addition to the attributes/functions you described. Thanks again and yes, I for one make to the end of all of your great videos.

I don't consider it a click bait title. Most people watching this are not just your basic people. They are more serious in this hobby.

[@nvlvdave]

Excellent video. I think it would have been much more useful, however, if you compared different component materials that are available and gave pros and cons of each - aluminum vs copper voice coil for instance. You could also show attributes of better quality subs and explain the benefits - extended back plate, for instance. You could take it even further and explain some basic Theile Small parameters - free air resonance, efficiency, etc. THIS would give a buyer the knowledge they need to be able to compare different subs and make an informed decision. Just sayin... I love your vids and your installs

[@CarAudioFabrication]

+DS Splicer thanks! It would have been difficult to explain all the design variables available while also explaining components and not end up with an hour long video. We could talk about design variables all day. Maybe a future video and now I can refer people to this video to make sure they have the basics.

[@brian69frmovale76]

CarAudioFabrication are you that guy on Craigslist in NorthHighlands

[@jeffreyokun2355]

I agree with the comment, but also appreciate the point of view of the video owner. It's mainly the claim that after seeing this video a person is well informed to get the best sub for their application that kind of sounded a bit misleading to me. There's so much that has direct impact on the sub performance that this wasn't such helpful in choosing a right type of sub. It was kind of like showing a V8 engine but not explain how the internals and enclosure itself translate to the power output. You can go and show a piston and say that's what generates torque but without additional information, just about any engine seems to do the job. But like I said, I do understand the video owner wanting to keep it not too technical for people who don't have any understanding.

[@hotrdenhell2]

Awsome video!!!!! Can you do the same type of video with for amplifiers?

[@danielmoraes9637]

Thank-you its a great explanation

I would think the reason others make a uniquely different design is for patent/copyright reasons and not to look like a copy. Thanks for the informative video, perfect timing because I'm about to disassemble a couple pairs I have and see what they need. They'll probably need a trash can.

[@user-xv9tc6yr5d]

[@DrBroncanuus]

brilliant video, thank you so much.....can you explain what would happen if I swapped my car sub driver 4 ohm into my REL home sub 8 ohm ?

[@mattw3406]

If any P3 owners come here and have a rattling sound inside your box, it's most likely the joint where the upper spider meets the cone. The resin cracks and becomes loose, introducing a very annoying vibration. It sounds like your trunk lid is vibrating when it's actually coming from the speaker itself. All you need to do is pick up some resin (Loctite 5 min epoxy works well) and run a bead around the top of the spider and the cone to glue them back together. Cheers

Just think..back in 1989 Rockford subs sucked. The voice pole wasn't long enough. They would reach the top, slide over, and lock up. The amps have always been top notch.

[@mrfreeman1763]

Yeah, I love their amps, but once you move past entry level on subs there is a lot to be desired. $500 for a T1 that can't handle the power from a T1500.1 or at least the ratings would suggest it, and based on my toasted P2, I find it best to slightly under power their subs, not about to blow $500 to find out.

[@033Fritz]

I’ll take a RF PRO -Series sun ANY DAY!!!

[@033Fritz]

Mr Freeman at last buy the punch or step up to powers from 93.5-2004! And now the current T-2’s or a T-3.

[@mrfreeman1763]

​@@033Fritz I have a single Skar ZVX 15. It can handle the RF T1500.1bdcp no problem. Only $350 for 3,000w max. RF T1 15 costs $700 and maxes at 2,000w. Their sub pricing to performance is a joke compared to other companies.

[@033Fritz]

Mr Freeman imo I think the companies that build the majority of the new subs are wanting us to buy 2k watt amps and try to sell based on the wattage ratings, magnet size and excursion. I’ll stick with the 600wrms rating of my RF PWR’s 93db sensitivity, no im not referring to the new woofers. The Skar ZVX15 has a sensitivity of 86.3, & that’s a 15” sub. Why would you want two alts, and god knows how many batteries to run your subs. That’s just my opinion though, & I hope you enjoy your set up. I’ll stick with a power 650 & some pro series, Pwr or RFR 10’s or 12’s.

[@thekeefcheef]

Thank you very much for this video! It's lead me to realize that there's a lot more to it that meets the eye. I don't know if maybe you could make a video talking about the different types of spider materials and cone materials and what type of tonalities they help to give the woofer other than the box that the sub is housed in. This paired with information regarding the wire size of the voice coil, I believe can help us to a better decision making process. This could also help us to identify the truly cheap subs that we would not be happy going with on a budget and lead us to the budget friendly subs that are designed for better performance and function. Thanks again for the video! The information is super helpful!
