Building 2.1 Sound Bar & Subwoofer with Bluetooth | PART 2 of 3 - by SoundBlab

[@TheDarkRaider126]

Nice to see fellow South Africans with skills like this

[@SoundBlab]

Thanks man!

[@Toid]

It is refreshing to see someone making a build like this by designing their own crossover and using a regulated power supply. Way to do it right! Looks great!

[@johncoops6897]

The regulated power supply is certainly NOT the correct way to do it. And there was a lot of effort to "make" the crossovers, however it's so far unknown if there was actually any scientific basis for that design.

[@SoundBlab]

123Toid Thanks, the power supply works well, but there are better options. This is an easy of the shelf solution though, and for the application sufficient. The crossovers was modeled and built after doing the box sims, measuring and modeling them in Xsim.

[@endall39]

You do very nice work and I agree with most everything. I did make a few observations, some of which may be be wrong due to video not capturing the item. Here they are: (1) you need to get some nut drivers, (2) I would solder all the speaker leads instead of the crimp terminals, (3) I would use spade terminals for the power supply connections, (4) I would not rely on hot glue for mounting the power supply. Heat can reactivity the glue and you don't want that thing bouncing around in there. Brackets and screws are best, but gel CA glue is better than hot glue. (5) Didn't appear you used foam gasket on sub speakers. I like to use threaded inserts on powerful speakers, especially with only four attachment points. That way you can torque them down more and use thread locker. Just my two, or five cents.

[@whyMDO]

Exactly. Agree with every point.

[@Bucefal76]

Yes, hot glue may not be best, it may loose contact with years.

[@SoundBlab]

[@jerichotm2122]

If I enjoyed it? No... I have never seen such dedication and passion in my whole life! This is the most elaborate project I've ever seen since I've subscribed to your channel! Every piece were in there places... you are A MACHINE! I wish I have more time to start my humble project too... Congratulations! Though, I did not understand why you've put two sub-woofers in the same enclosure in that position...? I didn't read the description thoroughly, but it looks like a stereo sub-woofer...

[@SoundBlab]

Thanks man! The two subs, well two are better than one right! They actually run mono and connected in parallel. Various reasons, they essentially help cancel out opposite enclosure resonance and also since they are small subs, give larger radiating area combined. Two also raise the sensitivity to match better with the soundbar output.

Can you please make one Wifi / Bluetooth sound bar with 6 inch woofers and 1.5 inch doom tweeters. Compatible with USB . Compatible audio formats MP3, Wav, Flac, AAC . Player could be a 2 DIN car stereo. Would like to have with VU meters for display.

[@BrianB2579]

.....We South Africans don't worry about sound tests because once your over 30 yrs your hearing is buggered and you are pleased any way to hear good stereo..... (Lucky you did not have power cuts while making this presentation....hehehehe)

[@RossLongos]

i hope one day i could build my own speaker. :D subscribed already. :D i want to learn more. :D

[@SoundBlab]

Thanks for the sub!

[@calieburger3113]

I've got so many questions on where you get all your materials like the wood and cushion foam and the white sound dampening stuff !!!

[@SoundBlab]

I get most of my parts from eBay, Amazon, Madisound Speaker Store of Parts Express. The other items like wood or polyfil I get from local suppliers.

[@stivson7313]

This is great project, im impressed and want to built it. I will be pleased if You can help me to explain what did You make in 8:55 and do a part list of it

That was the crossover for the woofers ans tweeter. Unfortunately I dont have that info anymore.

[@jasonwilson2867]

nice post.

[@nukularpictures]

So my typical question once again :D do you have the frequency response messured? :) And how did you come up with the crossover? Did you simulate it (since its visaton id guess boxsim) or did you test and messure it?

[@SoundBlab]

Everything was measured and modeled as for a proper speaker design. I used REW to measure the FQ response and then modeled it in Xsim. I use WinISD to simulate the boxes.

[@Festyxr4]

That subwoofer 😍😍

[@SoundBlab]

Cool!

[@telefon72]

Great work mate, keep it up!

Amplificador e Fonte no mesmo gabinete do alto falante, não ocasiona ondas estacionárias?

[@TheSketchy95]

sweet build!! I am looking at making the same thing but Id like to make the sub wireless (like many big brands, only a power cord to the sub) Would i put a transmitter on the sub channel and a reciever in the sub? is it that simple? (i have looked everywhere to find someone wo has done a DIY for this setup but I haven't been able to find one), thanks

[@SoundBlab]

Thanks! I dont have much experience with wireless subs, so not sure how you can solve it. Perhaps someone else in the comments has a solution?

[@JoshuasRecordings]

The subwoofers look nice (tang band), but what is with the drivers you put in the actual sound bar. They look like drivers from a cheap boombox. Overall very nice job.

[@jonathanbelzley2877]

Joshua's Recordings Visaton makes very nice drivers

[@SoundBlab]

Thanks. The sound bar drivers are Visaton FRS8-4's.

[@JoshuasRecordings]

Oh, okay. A lot of people on here use crap drivers, I didn't realize they were actually decent drivers as they looks like they are cheap.

[@EasyFold007]

Awesome...Mooi man mooi ;).... What do you think of the TPA3116? Have you used it a lot or in other projects? Keep it up... geniet die naweek..

[@SoundBlab]

Dankie! I have used this particular amp many times and I am very impressed with it. It is one of the better TPA3116 bluetooth amps I have come about.

[@EasyFold007]

Thx, going to give it a try...I used one of the "all in" Wondom/Sure Electronics amplifiers (not 2.1 only 2ch) but I was very disappointed. Although it is fully packed with add-ons the amplifier didn't perform very well. Maybe for some people it will be enough but the audio quality for what I was building (small project) didn't work well. Dear Lord you in RSA must pay through your neck to get things from PartsExpress, their shipping outside of the States are crazy?

[@EirArnadottir]

Wow well done

[@meoraiman8706]

Can you share what electronics part that u use to combine speaker on soundbar? The diagram?

[@prathvirazz6960]

Please tell me which type motherboard and supply used

[@alexandrelanhoso5538]

It's a nice build, I see you paid atention to some minor details, crimping the terminals is a good and fast way to go, specially since you're not dealing with high power. But, from a technician ponit od view, you made some mistakes. I'd not put any electronics inside acoustic boxes, cause the speakers will cause a significant amount of vibration, this can break solder joints and components terminals, specially the power supply, that you dont have acces to the components. To patch this up, a good way would be to secure the components with silicone glue, that would dampen the vibrations and prevent them from falling appart. Another mistake is to use hot glue, it's actually hard to ensure good adesion of hot glue, most times requiring you to pre heat the base materials. Some would say that this would also cause a cooling problem, but I don't think it's a thing to worry, we're talking about maybe 100 W, and switched electronics, so eficiency should be greater that 80%, thus, little heating.

[@SoundBlab]

Thanks. Oh, I am sure I made many mistakes! It's often a result of not always having enough time to spend on the finer details or not always having the right part or tool at hand. Or I make the wrong design decision in the beginning and then it's too late to turn back and you make the best of it and hopefully learn from it.

[@alexandrelanhoso5538]

@@SoundBlab It's nice to see someone actually replying to a coment on such an old video XD. Sorry for bothering when you may already have aknowledged and adressed these mistakes. I too usually make some mistakes, but I find it extremely helpful to from time to time, look back onto past projects and think about ways to improve, and its really helpfull when you have a third opinion. 1+ sub on your channel, I see you take audio with the proper respect, use good quality materials and pay atention to details as fine as to use proper grill fastners. Keep up with it, you do it good.

[@adign027]

are those two subwoofer drivers connected in series?

[@eliezersureck2712]

2 + 2 ohms = 4 ohms in series

[@ravenmooore]

What was your crossover configuration? :) Can you help me out? I built my first Bluetooth speaker with a plywood enclosure, and it somehow sounds 'hollow', is it because I don't have filling? Or it's wrong material? Or box volume is too small? Any recommendations sir? :)

[@tobias5811]

Paolo Pabalinas you have to use polyfill to make the speaker Sound better

[@ravenmooore]

Tobias Sandkuhl thank you What if I can’t find polyfill? Can I use polyurethane soft foam? Or you know another alternative?

[@tobias5811]

Sure you can use any foam made of plastics like polyester. I dont recommend other fillings because they can ruin the voice coils

[@ravenmooore]

Thank you once again! Can I ask a few more things? My portable speaker has two, 2 inch Passive Radiators. Should I still put some foam? Will it make my passive radiator 'weaker'? Or it's really recommended to? I also have two tweeters, should it be isolated from the full-range drivers? Like it should have a partition?

[@tobias5811]

Paolo Pabalinas Foam is for passive radiators not as important as for ported boxes, but in my opinion foam is always better. You dont have to put the tweeters in an extra box, the tweeters have a plastic cap at their hole backside that is inside the box so the pressure from the fullrange drivers dont do anything to them. I hope i this will be useful for your build;D!

[@jimmy-197]

How do u calculate crossover value or in which site

[@SoundBlab]

I measure the drivers first and the model the XO in software called XSim.

[@user-tj1el9uo1m]

Hey sir I will buld the same setup like you and therefor i watch videos on KZbin but what it is that with thing you put en inside the tweeter box en whey you do that ?

[@SoundBlab]

I assume you are referring to the crossover board that I assembled. These are electronic components in a specific configuration that was determined via measurement of the drivers and software to cross over the full range drivers and the tweeter at an optimal frequency.

[@user-tj1el9uo1m]

SoundBlab i mean that thing on 12:21 sorry my english is not good 😃

[@SoundBlab]

Ak Ok. That is a polyfill material used to dampen the enclosure and/or prevent standing sound waves from building up inside the enclosure. It is typically found inside a cushion. You can also use felt or open cell foam that is used for couch seats etc.
