Back into car audio heavey after a 25 year hiatus. Sooooooooooo much has changed, beyond awesome I found your channel! Appreciation from Willcox AZ!
The coil and soft parts you sent me with the 6 gonzo jr motors worked out great for my 15s. Fs 26, vas 2.4ft³. Had them going in a 6th order but figured out that they would play better in a 4th so changed the box and damn. Made a huge difference. These subs are getting down. Have 6 of them on 3 4500 watt amps in a b pillar 4th order wall. I just need bigger amps bc they can definitely handle more. Also 192ah of headway for power. Thanks for helping with this awesome equipment man.
Wow that's a super small VAS for a 15.
This answers all the questions i ever had, you teach a lot, all the little hints overtime, have a great day! Keep it up, some lessons are learned rough!
This is one of the most informative videos I've seen you do in a while. I appreciate the details about how the electro-mechanical effects effect the T/S parameters and real life performances.
Oh yeah. It fits
Great video
Glad you enjoyed it
How come there's not aluminum around the outside of the coil so it can't turn to spegetti mess getting hot before the magnet wire glue is set and help it cool. Heard of a gauss meter to test magnet strength. Seems like fiberglass cloth works with gorilla glue instead of the rezon for cone making. Think the imax low frequency drivers enclosure are tuned 24 htz seen something about the resonant frequency of space sound is played in.
If I can’t find a coil the same wind height, what effects will using a coil with a longer/shorter wind height have?
It depends on how much longer or shorter the coil is. Share the situation here so we can check it out
I have this love hate thing going on with your channel. This video content was awesome.. great delivery of information.. your knowledge experience is enough to keep people interested. You don't gotta bash on every body and be so negative to have great content. Your a teacher naturally.
I guess all you want to eat for breakfast is birthday cake and have a good time. That's not real life. That's not who I am.
Your such a smart guy . It's obvious. I just was thinking there's more to be learned when a person has that humble confidence . But no matter I'm not taking a shot at you. You did me nothing. I enjoy your content mostly I am subscribed . Thanks
@@joshuameyer7342 The better question is, "Why are you looking a gift horse in the mouth?"
So would you say aluminum coils have more cons than pros and do you prefer copper coils over aluminum ones? Just recently purchased an ampere audio Rev 3.0 V4 15 inch to run in a 3.5 cubed ported box on a bc6k at 1 ohm. I wanted to try these subs out because there’s not a lot of info and videos on these subs so I was very curious about them.
No it just is sometimes difficult to find really soft spiders with leads for aluminum coils. When you're designing a woofer though and you can have any parts you want you do all that research ahead of time so it works out for you if you're an OEM. If you're someone like me you have to deal with what's available in the market and that's not a lot considering that this industry is not aftermarket friendly. People think I don't like Lord of bass but George has given me a huge index to access that I could not afford on my own
13:04👏👏❤️😂😂😂..."it rubs the lotion on itself".......
Glad you caught that.
I have a sundown x12 v2 and am wondering about adding mass to play lower. Also have have always wanted carbon fiber dust cap just cus it looks cool. would that be worth it to do or just a waste of time?
I think it would be a fun project. Do you have a way to get the TSPs?
@@RobotUnderground I dont have a way to do tsps. Would need that and would I have to do a full recone or just pop the dust cap off somehow?
@@freque1257 You can cut the cap off and then put an inner cap into place. You can do it a couple of ways. Epoxy the inner cap into place. DO NOT trim the former down as stupid Jacob has the leads go all the way to the top of the former. If you need an inner cap and some epoxy, I can help. Text me direct with your name and shipping address, 6023126504
So at the end the reference to the wolfram sub. Is there any benefit to sound reproduction by limiting travel on a massive motor and suspension combo like that?
Only to extract a tiny bit more value from the customer and into your pocket if you are Wolfram/Collin
What modeling software are you using? WinISD?
I don't use modeling software anymore I have an instinct for it now I used to study blah box back in the day and just plugged it in and saw what happens when you have certain characteristics and qualities that you see in the numbers
Killed my confidence lmao i thought the evl18 i rebuilt sounded better lol..i thought it was cause the cone is deeper now lol...very informative busted my bubble😂
Just want everyone to know stuff.
@@RobotUnderground I know was just playing around lol...I did not know and now I do so I'm glad I watched the video thank u
@@RobotUndergroundhope u will have time to answer a quick question...If I repaired a coil with a small gauge of wire will that make the subwoofer cut off due to small gauge of wire not being big enough to allow current to pass through?? Like restriction that can make amp cut off due to the power not being able to push into the subwoofer?? Bare with me I'm just a dumb ass building my own subwoofers lol 😂
@@johnoates3326 Sometimes the amp will detect a problem and shut it off. Just do a recone if you can.
@@RobotUnderground ok thank u time to start saving lol...had to learn the hard way...But hey lesson learned for now once again thank u
Oh crap, nice video. Some of the terms are foreign to me, but I’m figuring it out. Im more interested in home audio, music sq subs. I’ve been trying to figure out, is it better to run a 12inch vs 15inch. Also a lighter 15, or a 12 with a massive magnet.
For home, just look for value and low Fs. You can text me direct and we can review some options for you. Let me know your name and shipping address as well. 6023126504
How about some 6.5" Subs (4 of them) like what I am trying to accomplish
@@1Patient Small subs are a waste of time and money.
Do you have a store front for your Rebuilds?
Nope. I just work in a warehouse at home. I do have visitors sometimes on the weekends. Just text me direct for an appointment. 6023126504

What about gluing two coils together?
I'll research it.
Copper is so much better at staying cooler and dissipating heat then aluminum I think it will always be best. Just pay for proper spiders etc
Have you played with EMS drivers?
EMF? No.
I wonder how the SR. Woofer looks like...😊

16:28 I work for my money, unfortunately, actually, I'm proud that I don't fit into the other demographics, and if I have anything, it's because I worked for it and earned it.
need to get rid of magnets and use 2 coils against themselves
👍👍👀👀👍👍
Use Flux when soldering!
There's flux in the core of that particular solder.
1.) what is the application?
2.) how much space is available for enclosure?
3.) how many watts is your amp?
4.) what load impedance is your amp designed to run at?
These are some good questions to determine what woofers to get.
More cone area = easier to make bass. *look up cone diameter vs area of woofer chart online
I think i would get along with you. Dont agree with everything but seemingly most. Im outcast in car audio scene. Telling people that companies with cookie cutter amps dont engineer their amps. Pointing out the snake oil sales tactics of companies like dd sundown ect hurts butts.
Beware. They hate when you point out their mistakes.
@@RobotUnderground 100%
Had a few massed produced skar amps and fucking fried a woofer was clipping it very bad I like the quality stuff and it’s pricey but you won’t regret it and it last
i wonder what silver wire would do... single layer wire
Well, you could get lots of windings in there
@@RobotUnderground right, but i was thinking because you might be limited from silver's weight vs copper but wondering what the higher electrical conductivity would do... but i also dont know how silver's magnetic properties are
@@narmale Well if it was worth it, someone would have already done it right?
@@RobotUnderground well... oem wouldn't do it... far to costly
and i cant search google for the last 10 years since they have gone to hell
also edison didnt invent the iphone now did he? :P
Some of those funky 8s like Skar the box the factory suggests are pretty big tuned to like 50...worthless
But you can feel the mid-bass peel your face off
@@RobotUnderground lol..
