Wow ... I just started watching your videos and I LITERALLY had no idea before but now I am just blown away ... love watching , thanks for your channel !!
Awsome video! I love when people fully explain the math of what their doing, it will deffinitly be going in my notebook of formula's so i can use it in the future!
yo can i get a copy of that notebook?
I’m putting this in my saved so I can refer back 👍 I used to just pop some out of old circuit boards! But now I can actually use better specific ones 👍 thanks 🙏 I’m learning a lot during covid break out! 👍👍👍
Hey friend, thanks for advising people to protect their car audio tweeters in order to limit the low frequency bands. My home lab experience suggest that when you are soldering a capacitor, (4:29) the heat of the hot soldering iron tip under five (5) seconds will not damage the capacitor. But for soldering any other sensitive electronic components (such as diodes and other 'semiconductors') then one might needs a heat sink (and that does not need formal tools but can improvised by using almost any plyiers, such as the needle-nose ones, and rubber bands holding onto the handles.)
Your videos have been unbelievable. So much information and knowledge it's very helpful! Really appreciate it. Been installing systems for 10 years and still learn a ton from your videos.
i appreciate your honestly and humble nature not afraid to say you arent the best. i try to always do the same. theres always something new to learn! never cut your brain short! 👍
dude same here. i feel like even just the extra confidence that i get from his videos makes my builds/installs noticeably faster
Been following you and watching all your vids for years brother. Keep up the great work!!!
i cant tell you how much knowledge and even better how much confidence you have given me from watching your videos
Once again, very informative and very nice explanation of what your doing and doing a very clean job! Thanks again 👍
Thanks for making all these very informative videos. You have saved me so much time and resources by explaining it so very well. Keep up the great work.
Agreed
I really could’ve used this a month ago before I blew one of these same tweeters. I’ll add these caps so it doesn’t happen again. Thank you for posting this.
I love that you did this video based off the very tweeters i have. Theres 4 of them going in, ran via dsp, but focals not cheap ill add the capacitor thanks!
A well thought out on protecting the tweeter excellent tutorial and demo
Some things never change. We did the same thing to protect the HF compression drivers in PA systems in the '70s. You only get 6 dB/octave but that's all you need for the purpose. You can also find a voltage that they blow at (usually more than the rated voltage, so that's trial and error) so it's like a fuse.
One case where "putting a cap in it" is actually a good thing! -Gangsta D
True, don't be a big dummy.
He forgot to say that the cap must absolutely be a bipolar one, and that the voltage of 100V is recommended.
Big D in da house..Lol
@@InXLsisDeo 5:51
How about a dddddddddddddddd lol
Thanks I never thought about that makes since and now i have even more research too do.
Awesome video, been waiting for this!
It was really efficient! Thanks for the video!!
fantastic! I've been waiting for this.
You are the best car audio installer teacher on the planet! full stop.
I appreciate that, thank you
Finally, I found a great video about this stuff. Thanks!
I love this guy. He creates some amazing art.
Another superb vid from da man. Really appreciate your insights and advice; thank you.
Very good tutorial.. Thank you Mark
Very cool and easy to understand!
Thanks and cheers.
love this channel number one on pro audio tnx Mark!
Finally, someone who explains these things in simple things and not drown everyone with math. Subcribed!!
Audio Control has been around for ever. They make great sounding components.
excellent tutorial, thank you very much! keep it up!
highly appreciated info bro 👈
thanks 😀
Glad you enjoyed thanks.
thank you very much for your tutorial!
It also nice to put some tapered heat shrink over the ends of the heat shrink you put over the crossover capacitor protection.
Job well done. Thank you sir..
loco, gracias por compartir tu conocimiento, saludos desde Lima - Perú !
I like your videos greetings from mexico
Thanks the Boolean algebra book needs dusting off but I got the idea of what you were on about gonna check out my circuits now 🙏 thanks
This is a great idea!
Gotta keep watching them vids. I keep learning every time. Keep up the good work.
Nice Video.Thank you
Excellent excellent video !
Audio control is rock solid and they have great customer service unlike many other companies. Your lucky to be sponsored by such a great company
I have a Audio Control LC 4.800 amp with a pair of Audison 6/9 APX on the rear
channels & 4 Audison AP1 tweeters .
two connected in
parallel for each front channels 150 RMS on the tweeters with the AMP giving 200 RMS Would you add the crossovers that are included with the tweets? Your input will be appreciated. Thanks
@@boondoggesp7836 active crossover is better than inactive. Protection is necessary. Give audio control a call to find out which model would be best for your setup and experience their great customer service for yourself
Thanks I was leaning in that direction But some say without protection ✌
Awesome, thanks for the info! I ordered some Kicker speakers and I noticed they came with two sets of harnesses. One with capacitors and one without, I was curious as to why
Excellent thank you
Excellent!! Thanks
Make sure it says "NP" on the label for non-polarized, meaning it has no polarity. Those capacitors are specifically designed to work with the variable AC signal that is speaker audio. If you see ( + ) or ( -- ), the capacitor will eventually fail as it's a polarized capacitor made for DC only.
Thanks brother
Damn I needed you when I was actually into car audio, lol.
Great vids!
Loved the math tutorials...
👍😎👍
THAT MATH TUTORIAL BROUGHT BACK BAD MEMORIES🤦🏻♂️🤦🏻♂️🤦🏻♂️
La información contenida en tus vídeos ¡Vale oro!
Thank you🙏
I love your videos and have learned so much! I have a question hopefully you can advise me on. I've got a set of Infinity Kappa 1.4" edge driven soft dome tweeters that I want to replace my factory tweeters with (21 Ford Super Duty with the factory B&O audio). I believe the factory Ford tweeters have a bass blocker so I'm assuming the B&O tweeter circuit is full range. The Kappa tweeter is part of a component set (90CSX) and the crossover specification on the component set is 5kHz. I don't want to use the Kappa crossovers as they are large round (hockey pucks) that won't fit in my dash near the a-pillars tweeters. The Kappa tweeters are 2.5 ohm and based on a 5 kHz low frequency cut off, I could use a simple non-polarity 12uF capacitor which would be 5305 kHz cut off. My primary question is according to your video I should try and set the crossover point between the resonant frequency (Fs) and the published crossover point of 5kHz. I have been unable to find the resonant frequency specifications for my tweeter. Should I just target 5kHz or should I go lower? Is there a typical Fs for a similar size tweeter I could use? I feel that 5 kHz would be safe but I don't want to lose lower frequencies if the tweeter can handle it.
Well done a good video. I tried to get to the formula which capacitor fits my tweeters, and can't find one. I'd love your help on which one fits the Cerwin-Vega XLS-6C and Cerwin-Vega XLS 28?
Thank you.
Love this Channel
I have questions for you... I love your info and your channel and all the videos you post. I am considering installing an audio control epicenter plus on my 2012 Escalade ESV LUXURY and want to do it with a wiring harness instead of finding, cutting and soldering wires into the harness. Is there a harness that has this interface? I just want the plug and play ability to allow my BOSE system to work with an easy plug and go. I am adding 3-15" Eclipse subs, a Goliath 4k amp with a yellow top, second battery. Please help. And keep up the awesome work.
I just did this on my tweeters, very helpful!
Great video.so would you still need to put a capacitor on a supertweeter if your using a 3way crossover before going into the amp? Was planning on using a 3 way crossover to connect a supertweeter and a 8" midrange and then connecting it to a lc4.800 bridged to get more power to the midrange(400rms)@4ohm.also how do I make sure the tweeter doesn't get no more than 100rms or less.would the capacitor n crossover,dsp take care of that?
and using dm-810 DSP to adjust.
Amazing video. One question, Since I have an empty slot for tweeter at my car pillar, I want to add a tweeter and I already bought one. I saw that my tweeter already has a polarized capacitor attached to its terminal. So, do I still need to use a crossover for my tweeter? For additional info, my car speaker system is 2pcs "2 way coaxial speaker" and 2pcs "mid base speaker". Appreciate if you could help.
Cool...thanks for sharing.
You bet
Good info
Thanks for the video I was looking for what does tweeter do it the car and answer that and more
great video
Thank you
Love the tip to leave a tab in case you need to remove, the tesa tape equivalent I use is very hard to find the seam.
Clean assembly.
Mark, great video- quick question- I just purchased the lc 6.1200,& am using a audison bit ten d dsp. I have switched my mids,& tweeters directly to the lc6.1200-( active) as you know, I can not turn off the crossovers built into the amp. I have the dsp for tweeters at my crossover point,& for added protection, I have the front channel of the lc 6.1200 also set to that same high frequency. In doing this, in case the dsp stopped working, isn’t my lc6.1200 crossover point acting as a “fail safe” protection for my tweeters, vs. adding the capacitor? Thank you in advance for answering this question:)
great video as always!!! my morel ccwr254 came with a pair of capacitors which has not the label BP on it, should I be aware of the polarity?? thx
What about the phase delay introduced?
For example if we have at 4500 Hz a 2nd order low-pass and a 2nd order high-pass filters, the former for the Woofer and the latter for the tweeter we obtain a flat freq response, but with this capacitor we add a new pole in the transfer function of the overall tweeter High pass filter.
And what do you think about having that kit Focal KX2 120W 2 Ohm in each door powered by audiocontrol d-61200 which has 200W per 2 Ohm Channel?
Thank you Mark
I love your Channel.
P.S. I have used MATLAB to tune the band pass filters of the dsp and crossover together with and without capacitor and in the second case It Is a bit difficult ti obtain an Ideal flat freq response.
With your experience What do you think?
4:30 Finally someone that knows how to Solder!!!
Just gonna SAVE this for further reference
How do you save on You tube mate?
I would put the helping hand for soldering on the other side of the solder. Between the joint and Capacitor to act as a heat sink. Extra protection for the component.
"Just do the math because it's really not that complex" *me still counting with my finger & toes after the explanation*
Yeah ... where is the cheat sheet table link?
2009 Chevy Avalanche. Just installed Pioneer amp and 4 Pioneer 6 1/2" door speaks. Adjusted amp gain within specs and sounds AMAZING! But.....after cranking for 2 days during my 1 hour commute the factory tweets became raspy. I now have Pioneer TS-A300 tweets ready to install. They will fit stock location but I'll have to hot glue them in the A pillar factory speak cover. They came with HPFs filters. Comparing the stock ones to the Pioneers, the magnet on the stock is much larger. I figure it's a cheap material compared to the Ps. Gonna hook up the Ps tomorrow & see if they sound better. Wish me luck.
So I used jumper wires to attach the Pioneer tweeter in place of the left tweet and it initially sounded better then the factory tweet at 90% volume. I then played a high pass frequency tone on youtube from my phone. About 45 seconds into the tone the tweet started smoking then it stopped all output. I removed it & put the factory tweet back in. The Pioneers are rated 100 watts continuous. My amp puts out 60 watts max per channel. I used my Fluke meter to compare the now bad tweet with the one I had not used yet. The tweets and the high pass filter they came with both tested the same, 6.6 ohms for each tweet & 6.9 micro farad for each HPF. I put the bad tweet back in and it played the test tone for about 20 seconds till it started smoking. I am going to return the Pioneer tweets. Anybody got a recommendation for a great tweet?
So do I run this directly to the front component? Do I just set the crossover for the component at the dsp and let it ride? Does the high frequency roll off of the mid bass?
Hey Mark! What if your not going active on your tweeters and have a crossover? Can I use a capacitor to get rid of turn on pop?
thanks
Q.:
1. why 3.5 Ohm? Impedans is 4 Ohm in manual...
2. why 15mF ? Inside crossovers build in capacitors 2500-3500...
Thanks)
P.S.: Good job! 15 years working as installer but You projects is perfect. Deuch quality in The USA)
For a more exact value, in the grand scheme of things 3.5 vs 4 doesn't really matter as this cap IS NOT the crossover, but just to protect if something goes wrong. The caps in the ACTUAL crossovers are combined with several other electrical components and much more complex. Again the cap on the tweeter IS NOT ACTUALLY BEING USED, until things go wrong.
Love the video and got me thinking I could do this. Except alpine doesn't list any info like this for their tweeters. Called alpine and was told it isn't listed because it isn't necessary. So I'm sol?
Thumbs UP Bro.... Sharing is caring
What if someone has a 2way or 3way speaker? I'm working with some JL C2 350x 2 ways and dont want to blow them up. JL doesn't list these specs. Are there caps built into these? Any advice would be greatly appreciated. Awesome videos btw. Best on the tube!!!!!
Also a side note, while this is a great practice for customer systems -- A capacitor needs to be a decade lower then its crossover point to offer zero phase shift. this is only applicable with competition grade SQ cars but it is very important for perfect acoustic phase coherency. When using a 4000hz crossover slope with a 24db LR, 4000hz will be 6db down from 8000, and 2000 will be 18db down from 4000- If you used this capacitor then you would be causing a phase shift from 3000 down and on to the critical range where the tweeter hands off to the mid range. In a competition grade car it is important to make sure there are no turn on pops to begin with and one would only have a inline cap in the event of a DSP failure. But this could be likened to having a reliable daily driving car that may not have peak performance but lasts forever and having a race car that is less reliable daily but has much more impressive output in exchange.
Aren’t phase shift issues addressed during the RTA and time alignment configurations while tuning a system?
they have SQ competitions?? how does that work???
I have a question for you, I purchased a set of Infinity Reference 3032cfx and inside the packaging were 2 bipolar 270uf 50wv capacitors but i also noticed each speaker had a small capacitor that is 4.7uf 50u on them , so i use the other included capacitors as well? If this basically both high and low protection ? Thank you
I’m using Alpine type R tweeters, would you still recommend doing this? Thanks!!
Nice video, very useful.
One little question:
From where comes the 0.159 in the counter?
Many thanks for the help.
its 1/(2*pi)=0.159
You Do A Great Job Boss... (Shoud'a Been A Teacher..) Subscribed..
This video reminds me why I failed algebra!!
Me too! Lol
I was good at it, but it has been 20 years, I don't remember any of it.
Algebra was easy. Calculus, on the other hand, was a b*tch.
FWIW, 100V @ 4 ohms is 2500W. As to a poly cap versus an electrolytic, the poly cap won't dry out over time and shift in value like the electrolytic. You could end up with the cap lowering in value to the point that it drops below the desired frequency. Granted, this takes some time but some of us run the same gear for years.
I wouldn't put this much work in something that's not a forever car.
I'll have to check and see if the OEM speakers on my Mustang has this electrolytic in series with the tweeter. If not, where do I get specs on the OEM tweeters in order to calculate capacitor values?
(5:08) I think "AccuBASS" harkens back to AudioControl's Phase Coupled Activator, from back in the late 80s to mid90s(?). I have two of their old PCAs for home use and I will always have a soft spot for them. I prefer dbx's 120x-ds for bass restoration, though. It's more granular as for as the range of frequencies it uses for the restoration circuit. But we're talking 6 knobs on a dbx compared to just 1 or 2 for an AC unit, so it's a no brainer as far as which is more simple to operate. Anyway, I've rambled enough. Nice video! :)
Do you have a video on how to run speakers active? Specifically tweeters? Matching rms power of the tweeter to the output of the amp? I can't seem to find a decent video on this. And I don't want to run too much power. I'm using a d6.1200 and I want to run my front stage active
Hello. If i already use original filter for mid+tweet i still need to install this resistor? For more better quality and keep more save my speakers?
0,159/3000x3,5=0,0001855. Where do you get 0,0001514 from? Maybe I am counting wrong?
Sure ..sounds good to know
After seeing that math. "ok, we'll just keep replacing them tweeters"
me too!Hahaha
Lol yep
Screenshot the part where he is using the chart on laptop as reference. No math needed.
That shit is like basic 5th grade algebra. You don't even have to rearrange the equation!
yep! simple as
@caraudiofabrication You mention this is a failsafe capacitor - If I want to add a tweeter to a system that does not currently have tweeters (by tapping into the wire going to the midrange speaker) and therefore currently no crossovers what would you recommend instead of doing this?
Mark, any idea what would cause a turn on ‘pop’ after placing a protect capacitor inline to my tweeters? I followed your video, which is excellent!!! If I remove it, no turn on pop- I am using a dsp, but want added protection. Thank you for taking the time to read and respond👍🏼👍🏼👍🏼
I would guess that you placed the capacitor on the incorrect lead of the tweeter. The capacitor should be on the positive side *if* the negative terminal of the amp (and the tweeter) is grounded. The capacitor will charge with the voltage that causes the turn on pop. If the capacitor is on the negative side. The tweeter will float up to the turn on voltage, and in the process of going from 0 V to V_turnonpop will make the noise. With the cap on the other side, the tweeter never changes voltage, and the diaphragm never moves. However, the turn on pop will not damage the tweeter regardless of where the capacitor is relative to the tweeter. The noise in this case is the momentary charging of the capacitor (which takes 1/F in time, less than 1 msec). Without the capacitor, there is a DC voltage on the tweeter (at all times) and thus a DC current which sifts the diaphragm at all times, which damages it, especially when music is played on top of this DC voltage.
So do I need a capacitor and a crossover or is s capacitor the crossover? I'm asking because I got some decent component speakers from jbl and they came with one of those square looking crossover that has inputs from the amp or head unit and has outputs going out to tweeters and mids. So do I just use that or do I also add a capacitors?
is this protect capacitor applicable to/with passive crossover? does the value will add up to existing capacitor on the crossover, lets say for example crossover(built in) is 10uF, then I add another 15uF, will it sum up to 25uF?
You should review the 165FX Expert Series focal component set.
2 questions:
1- Infinity Ref 3032cfx come with capacitors, I assume they would be the correct ones to use, correct?
2- Is soldering necessary, or can it be twisted and wrapped?
