My Awesome Little Boombox





Introduction: My Awesome Little Boombox

DIY Soundhack Contest

DIY Soundhack Contest

Hey everyone

Due to my recent success in building my first Boombox ( you can view it in my page ) , i got some extra spare time , so i decided that the best way for me to utilize it is by building something !

i saw those two crappy cheap speakers that i got on eBay for 35$ ,so i  decided to do something with them , instead letting them fill with dust


Step 1: Shopping List

1 .80x80 cm Plexiglas 
2. Screws and nuts  - about 70 pieces from each
3.Battery 12V 7 amp
4. set of speakers - invest at least 50 $ if you want to get a decent sound
5. Amplifier - got the Lepai T2020+ AMP- excellent amplifier
6. Wires for the speakers
7. soldering iron and soldering wire
8. different angles and angles - different sizes
9. Time , patience , and little self confidence .
10. Clamps
11. Hot Glue
12. Drill + set of drills 
13. Coffee !!

this whole project took me something like 16 hours ( working time ! ) - two days in total


Step 2: Sawing the Plexiglas

Carefully saw the Plexiglas .

I broke at least 3 pieces during the sawing till i got the hang of it .

the most important thing to do is use a sawing blade that is meant for metal - it has small Saw-tooth.

Step 3: Start Cutting the Angles According to the Size of Your Boombox

Step 4: Start Attaching All the Angles , Side by Side to the Plexiglas

Step 5: Start Screwing the Bolts With the Nuts - Phase 1

this first phase is just for the adjusting of the pieces together.

this is the Tedious part , it takes a lot of time ! to match each angle to the Plexiglas , it takes a lot of time drilling the holes in the correct places .

 overall after building my first Boombox i took my time with this one , drilled each and every hole in the correct place and made sure not to brake the Plexiglas or drill in the wrong place - it happened a few times.

Step 6: Add Hinges for the Upper Case

Step 7: Attaching Everything Together Phase 2

place all the bolts and nuts and all the pieces of the project till it completed.

 make sure that  it works , and sound OK, and make sure that it is built OK .

 then , disassemble everything  so you can tear off the Plexiglas protection cover  - Nylon 

Step 8: A Few Extra Views -

Step 9: Create a Switch for LED Light

took one little switch , connected ( soldered ) it to two wires and one small LED stripe.

 look even better !

after connecting the wires , i putted Shrinks ( to protect the wires )

then i heated them with a heat blower to " shrink " them

andddddd connected it to the Plexiglas 

Step 10: Create Two External / Internal Bolts for Charging

after hours of using the Boombox , i will need to charge it via an external charger ( 7$ on eBay )

Instead of removing the battery each and every time , i drilled two holes on the side of the Plexiglas , inserted two bolts and closed them.

 Then , i connected the internal wires of the battery directly to the bolts , and from those bolts to the Lepai amp.

Left bolt  -positive 
Right bolt  -negative 


Step 11: Gluing Wallpaper on Bottom Angles

i glued some wallpaper on the bottom Angles , it`s much better looking then the plain steel 

Step 12: Final Assembly

Slowly start to assemble everything back together , make sure not to scratch the Plexiglas.

Step 13: Final Assembly - Final!

Step 14: Seal With RTV the Sides of the Boombox

we need to seal off any  small opening the Plexiglas  , in order to create a sealed space - for the Reflex port  to operate properly 

Step 15: " Beta " Video

hope you enjoyed!

Here is some small video ! - the sound is awesome! 

Comments are welcomed  :)

Step 16: One More Cool Video !

    Great build! I am thinking about doing an airplay speaker system and I would like to use Plexiglas (it is cool to see the actual parts!). If you don't mind me asking, how well does this material handle vibrations -especially without insulation - and, out of curiosity, did you find that your reflex port works as well as a bass reflex tube? Thanks!

    That`s sound awesome!

    maybe i will build one my self

    what parts do you need exactly for this Airplay Boombox?

    well about the vibrations, if you will look at my first boombox on my main page , it`s much bigger, and the main issue is that it has a real round Reflex port on the front,
    more over it has an inner partition that isolates the front speaker and gives it a more acoustic build.

    one both the boomboxes the reflex port works perfectly fine ! if you will get your hand close to that port while the music is banging you will feel the " wind " of the woofers

    actually that quite amazing

    Plexiglas i a very cool material, recommended!


    Very nice "ible". I have to agree with SuperTech on the leds. This project just begs for flashing lights. And personally, I could see some really awesome Steampunk potential.
    Great Job.

    appreciate it

    I just ordered 2 of those lepai amps. Ready to have for the rainy day. I will use coffee too. Thanks for the inspiration.

    glad to hear !

    Build something and upload it here so we can enjoy it also ;)

    This is very nice, well written and nice and informative. I will be sure to try this soon, although i think ill make two speakers and use it as a mini Hi-Fi :) thanks


    hope to see you work soon ;)
