Building a Retro Style Bluetooth Boombox Speaker - by SoundBlab

[@robyone7729]

I spent many days watching tutorials and in the end I can say with certainty that yours is one of the best! Thank you so much for sharing!

[@SoundBlab]

Thanks man!

[@captainjim1010]

WoW finally someone who knows the basics of speaker building...

[@SoundBlab]

Thanks

[@chadgrimes5119]

the most disappointing thing about watching speaker builds is when they end the vid without playing it. what a boring way to end.

where is the sound test???? you dufferrrrr.......💩💩😠😒😒

[@ABDULMANNANsam]

hiiii.... i am from india 🇮🇳 and learn sooo much from your videos ....

[@Darieee]

Awesome word, as always ! You know, you could also set up the equaliser of the Bluetooth Board ... It's probably more hassle than making the filter for the first time you try it, but, in the long run for setups where you only want to correct the sound (and not do crossovers) it would be quite a bit more elegant/efficient

[@AbhishekYadav-dg4gi]

You are awesome speaker builder and I love your channel

[@MarkErikEE]

Nice clean build! And I like the color.

[@SoundBlab]

Thanks!

[@TheHoodik]

I’m here 50% for the build and 50% for the accent! 😉 Lovely build as usual! Really inspiring!

[@paulvanzweel8287]

I immediately recognised your accent as SA. Well done! you have created a very nice channel. I will be following. Nice projects!

[@SoundBlab]

Thank you very much!

[@revelairfanman6171]

DIY builds rule. No company manufacturing retail style BT speakers is going to give you the quality and power offered by a high quality and well designed DIY build for the $$$s invested.

[@paulf6768]

Wow looks great and so professional like all your projects, can't wait to hear it!

[@SoundBlab]

Thanks Paul.

awesomeness ... thanks for telling that awesome "sanding sealer" i used it today and its amazing

[@timonarthur]

Great Video! I was literally going to build a speaker similar to this one but with passive radiators on the sides. I hope you do a sound test at any time in the future so i can kind of compare the two designs.

[@SoundBlab]

Thanks. Yes, I will do a sound test in the upcoming week.

[@NafisZzamanrgb]

Really nice. Its looks great.

[@SoundBlab]

Thank you Martin. I am very pleased that you are happy with the build plans and the speaker! Your support is appreciated and helps to keep my channel going!

[@mmarfe]

Nice! It´s a pitty I live in Brazil and it´s so hard to get a hand on this tipe of accessories and quality speakers ... I so wanted to build that kind of stuff.

[@borisfwZ]

Thx for showing up this build. Amazing finish! Respect and thx again.

[@SoundBlab]

Thanks

[@JeanmarcW]

Nice work as usual. Looks great. Another Paul Carmody's Sprite variation Certain that it will sound great.

[@SoundBlab]

Thanks! Yes, definitely similar to his design, however I used different enclosure volume, dimensions and crossover parts.

[@Omlet221]

The driver is rated for 80-15,000 hz so wouldn’t you want to do a crossover with a tweeter or maybe something like the nd65 which can do 80-20,000 hz?

[@SoundBlab]

I could and have before, but for this one I didn't.

[@markandersonsa]

As always. A great build. Great share

Amazing. I love the color and style.

[@SoundBlab]

Thank you

[@ktozjadlciastka]

I've never build any "adult" speakers and have a small questions to understand everything better... 1. Why have you glued reinforcements after you painted the enclosure? I think It would be easier to make all sticky parts in the first place. 2. How the paint layer quality looks like? Are there some artifacts due to spraying in dusty enviroment? I have always problems with it :/ 3. Wouldn't wood screws with plastic tubes hold amp/bat PCBs better? 4. Is it a standard practice to hot glue "speaker related passive components"? I see a lot of people doing this. 5. For how long the batteries last? 3xAA is not a lot for 2x15W amp...

[@SoundBlab]

1. A build sometimes evolves as you go along and that is something I realised I did not do only after painting. 2. The paint finish is smooth. I usually make sure my workshop is clean before I painting. 3. Yes, if I had them on hand at the time. 4. It is a convenient, easy and effective solution. 5. These are 3.7V 18650 rechargeable lithium batteries, not AA. The last very long when fully charged.

[@ktozjadlciastka]

Thanks!

[@dghouse7140]

Nice Bluetooth box! I love it! 🔊

[@nvdwalt]

Beautiful AGAIN!!!!!

[@SoundBlab]

Thanks Nico

[@converdb]

Hi, love the style of your builds. You sure have an eye for design. Could you please develop a little, for those of us lost in audio theory, what is the coil+capacitor filter you install and where to find it? It'd be great to have like a basic explanation or point us in the direction of one basic video that could do that. Thanks in advance mate!

[@SoundBlab]

Thanks man. I can def consider doing that in a future project.

[@sense083]

Can you school me on the point of a crossover on a two channel stereo build? As I understood it a crossover is used to differentiate signals for a high (tweeter) and low signal?

[@SoundBlab]

It is a circuit to flatten the frequency response and does not fulfil typical crossover function.

[@JustAnotherAsianGuy2]

you did a great job !

[@SoundBlab]

Thanks

[@MCsCreations]

Fantastic work, man!

[@SoundBlab]

Thanks

[@billbird9625]

Nice build and great channel! Can you provide more detail on the parts you used to mount the amplifier board - specifically the screws and stand-offs used? The parts listed don't seem to match what's in the video. Thanks.

[@SoundBlab]

Thanks. The stand-offs are what is typically used for mounting PCB boards. I got them from my local electronics supplier. You should be able to find them online from a similar supplier. They should also be able to pride you with the screws. The stand-offs come in different lengths. Try these at Amazon: amzn.to/2Dmzvx4 , amzn.to/2BiNNNK

[@georgleiter7836]

Awesome great Job i love it

[@SoundBlab]

Thanks

[@yarkog7]

great build, but every time I get close to the end, always no sound demo, whats up with that? :-) Please make sound demos at the end of each build, thanks

[@SoundBlab]

The sound test is the next video on the channel.

[@fabricefauconnier4617]

hello, I bought the plan and I realized the bluetooth speaker thanks to your excellent advice and your video. the result is good. I would like to know if it is possible to modify it to have a little more power, should I change only the amplifier, or have to change everything ...?

[@SoundBlab]

Thanks for the support! You could try this amp form Parts Express: bit.ly/2VDp02u . It is a bit more powerful, but be careful, it might be too much for the drivers if you go full volume. It should be a direct drop-in replacements for the specified amp in this build though.

[@nonfakecreativechannel5765]

Perfectly done

[@KugelXFanger]

Any reason you did not go with pasive radiators?? Just curious

[@SoundBlab]

These Dayton Audio drivers can go quite low for their size, and I wanted to try this out in a vented enclosure with ports.

[@mambobond]

Very cool. I have never built a speaker enclosure, but enjoy watching the build there of. Non speaker related question - your circle cutting bit in the drill press, where did you get it? I am also in SA and can't say I've seen it on the shelves anywhere. Cheers

[@SoundBlab]

I think I got mine from Builders Warehouse, but you can also get it online here: www.tools4wood.co.za/product/circle-hole-cutter-adjustable-30-200mm-tccc30200/ and this one www.tools4wood.co.za/product/circle-cutter-large/

[@Bekim8310]

Hi I have actually watched this video a couple of times and enjoyed and learned from it. I have made 2 Bluetooth speakers with MDF. I have a question if you don't mind me asking. Once you round off the edges how to do you get it so smooth that once its painted the porous edges don't show? Does the sanding sealer all by itself seal it all in? Thank you very much!

[@SoundBlab]

Thanks. The sanding sealer is best applied and sanded in between layers a couple of times. Not just one layer. Then I apply an undercoat of spray paint, then top coat onto that.

[@TheFlyingKiwiNZ]

Where do you get your logo stickers from? And please do a sound demo at the end, please!

[@SoundBlab]

They are resin dome badges. Do a Google search to find a supplier in your area. The sound demo is a separate video after this one!

[@TheFlyingKiwiNZ]

Where can i buy parts to buil correction filter at 10:39 ? Thanks for help

[@TheAngelmiguel4u]

Awesome video I just love watching this type of stuff and I would love to build something like this but I'm pretty sure there are a lot of subscriber or people that watch that's that don't have the tools to actually make them like myself it would be cool if someone would make it and just sell it as a kit so the person can just screw some screws in plug some stuff tie some wires together and get it up and running maybe you should consider that just making everything and then selling it as a kit so the person can just build it at home kind of like those guys that build model cars all they do is put everything together and then paint it being that when they buy it it brings everything that they need now that would be cool and like I said maybe you should consider that and sell it at a decent price I'm pretty sure a lot of people would love that

[@SoundBlab]

That is definitely an option some day, but right now I do not have the capacity to manage such an endevour.

[@TheAngelmiguel4u]

@@SoundBlab I mean if anything you can have a patreon account to help you fund it or open up a GoFundMe account and that can help start in some kind of way I mean you could just start off with maybe two or three of them and then go from there I'm pretty sure your followers or anyone that sees this video and you let them know that they can get this and they can make him themselves I'm pretty sure everybody will back you up and maybe you should make a video asking people if they're into that type of stuff and then go from there that would definitely give you an idea if people would want that

[@Priyakulkarni000]

For 4s bms ,if i use 18 volt charger it is possible or not plz tell me

[@SoundBlab]

I don't know. I do know that the 4s will require 16.8V, but not sure if the higher voltage will be a problem. Maybe someone else in the comments can reply if they have the anwser?

[@TheRealDoubleT]

How do you select the correction filter?

[@SoundBlab]

The driver was measured in the enclosure and then I used Xsim crossover software to model the filter.

It is a nail gun or brad nailer.

[@samsideenadigun8387]

if i may ask? why did u put the sand sealer before u sand it ? i thought the tha sand sealer comes after u sand it? thanks

[@SoundBlab]

I will do an initial sanding to smooth the surface, then apply the sanding sealer and sand again. I will sometimes do a second coat of sanding sealer as well before applying the final primer and top coat.

[@nicolael.cardei476]

Awesome stuff! I bought the plans, thank you for making it available to purchase. How long the battery last on a charge?

[@SoundBlab]

Thanks for the support! I honestly have not tested it yet. It will also depend on the batteries you use and their capacity.

[@stanmarshall8202]

what was the total cost of the build?

[@xNOFEARx58]

Good work thumbs up but thumbs down for no sound test

[@PhaQ2]

Excellent work. Only one mistake that I've seen in this build. The coils will experience "cross talk" being aligned and in such close proximity to each other. Simply put a couple more inches of distance between the two and that should fix it. Or invert the coil in reference to the opposing coil.

[@lestergranger1685]

Cross talk??? The drivers are about 12inch from each other!! Theres no point in even having separate chambers. He even hints at standing waves... how much bass does he think this thing will kick out?? Look, you lot are buying into the snake oil of hifi waaaay to much. Just build a loud mono box.. nobody with ever compliment the stereo separation but you will be complimented on the build and how loud the damn thing goes.

[@supersteef]

It looks very good! Is it inspired by Paul Carmody's Sprite boombox? 😉 Also, Where did you get the aluminum knob?

[@SoundBlab]

Thanks! It was not the intention, but definitely similar to his design, however I used different enclosure volume, dimensions and crossover parts.

[@shaunkaufmann6091]

hey boet, great build! was wondering if the amp was a bit under-powered for the speakers or does that not make a difference ? bit of a noob here.

[@SoundBlab]

This amp works well in this combination, but I have also wondered if the 30watt per channel amp from Dayton Audio will make a big difference. I think it might help a bit at higher volumes where the smaller amp seems to run out of oomph a bit. It is an easy switch to the larger amp though. They use the same connections and are the same size board. I can definitely recommend trying it.

[@shaunkaufmann6091]

SoundBlab thanks for the info!

[@mastroitek]

wow that is great! What about battery life? :)

[@SoundBlab]

Thanks! I have never really tested it for that, but it also depends on the capacity of the batteries you use. But its definitely more than a couple of hours that I have had them play continuously in the past.

[@gedaskilnusis4443]

Hi mate. Awesome work. Your all projects looks very nice. I'm also going to do my 3rd boombox. And have few questions for You. How long does it play without recharge on full volume? What do you use for charging? How much mAh do these batteries have? You running 12v or 24? My first built was very simple, just a stereo from car and batterie from motorcycle, but you probably imagine how much it wighted lol. Now I'll try to build it with creative 5.1 system, as it has everything what i need - speakers and amplifier. And you van buy it used musch cheaper than new speakers and d class amplifier. Ofcourse it won't have bluetooth. But you can mode ir to. With these batteries that you use the speaker is much lighter, but i need speaker that will play on full volume without recharge atleast 24 hours.

[@SoundBlab]

Thanks. I have not done test to see how long this speaker will run on a full charge, so I honestly have no idea. In this configuration I charge the unit with a 19V 4.74A laptop power supply. These batteries come in various mAh versions. The one I have is 2600 mAh each.

[@lonhetrick]

Really well done! Where did you get the speaker feet?

[@SoundBlab]

Thanks. There should be a link in the video description :)

[@lonhetrick]

Thank you! I also wonder why most people recess the drivers and chamfer the edge of the hole. Is it for sound or just because it’s easier than flush mounting?

[@SoundBlab]

It's for aesthetics and to avoid reflections. If you mount the driver from the front you will see the flange, which in this case is not pretty. But if you mount the driver from the back it looks better, however you need a chamfer to avoid nasty reflections from the edge of the hole that can influence the sound.

[@carlosdylanspain8852]

A very good video Comment a detail. Could I activate subtitles in Spanish? Thank you.

[@dyllgold]

[@surajp6393]

I wish I could buy your plan but I don't have a 3D printer, so its better to do it by self because it's of no use as you can customize the size and design or as it is.

[@fUP420babe]

is there a reason you use mdf instead of a nice birch ply? is it just cheaper?

[@SoundBlab]

When applying a spray finish to the final product, MDF gives me a better finish than wood with a grain.

[@SoundBlab]

And yes, it is also cheaper!

[@rnytixxer]

Wonderful!!!!!!

[@SoundBlab]

Thanks

[@fuzzybee5988]

Why did you build a crossover if there is no tweeter?

[@SoundBlab]

This would not be considered a crossover, but rather a correction circuit. It is a calculated number of components that helps to flatten out the overall frequency response.

[@fuzzybee5988]

SoundBlab yeah, I actually looked at it again and figured that out, thank you for confirming!

[@yaghiyahbrenner8902]

the sanding sealer what product is that ? by the way good work really good work.
