Hi everyone! Thank you for checking one more project of mine. On this one I was reached out by Parts Express to see if I could assemble one of their DIY boombox speaker kits that they have. This kit has incredible value for what it provides. The kit includes:

• CNC Cut Plywood Enclosure
• TPS3116D2 Class D 2.1 Bluetooth 5.0 Amplifier Board
• Dayton Audio DCS165-4 6-1/2" Classic Subwoofer 4 Ohm
• Dayton Audio DS215-PR 8" Designer Series Passive Radiator
• Dayton Audio LBB-3 3 x 18650 Lithium Battery Charger Board/Module 12V
• 2 x Dayton Audio ND25TA-4 1" Titanium Dome Neodymium Tweeter
• 2 x Dayton Audio DSA90-8 3" Aluminum Cone Full-Range Driver 8 Ohm
• Wire, Hardware, and Other Components

Crossover Components:

• 2 x Dayton Audio DNR-8.0 8 Ohm 10W Precision Audio Grade Resistor
• 2 x Dayton Audio 1.00mH 20 AWG Air Core Inductor Crossover Coil
• 2 x Dayton Audio 0.10mH 20 AWG Air Core Inductor Crossover Coil
• 2 x Dayton Audio DMPC-1.5 1.5uF 250V Polypropylene Capacitor
• 4 x Dayton Audio DMPC-3.3 3.3uF 250V Polypropylene Capacitor

As you can see the kit includes many high-quality components for the speaker. The enclosure itself is made of precisely CNC cut 1/2 inch plywood.

I'll start the speaker assembly process by inserting the speaker terminals on the side panels of the enclosure, making sure the cables with crimp terminals will be inside the separate woofer enclosure. Using the wire stripper / crimp tool (in the tools list above) I cut and crimp two pieces of wire for the woofers. Make sure you use to of the larger terminals for the midrange speakers.

I then cut two pieces of MDF for the crossovers that would nicely fit on the bottom of the enclosure once assembled. Drilled the holes for the screws and marked the same locations accordingly on the bottom panel. I also drilled two holes next to the charging port hole for the power LEDs and I cut a small piece of plywood for the battery level LEDs.

Before assembling the enclosure I routed the inside of the amplifier panel - not necessary but makes it look neat and removes sharp edges.

For gluing the enclosure I used plain PVA wood glue and a brush to spread it along the edges. The pieces fit really nicely and don't require effort to assemble. A few clamps will ensure a good bond between the panels.

Once the enclosure has dried, I used an orbital sander to make it nice and smooth. After that I routed and sanded the outer edges of the enclosure.
I used a few screws as stands while spraying the enclosure. I started by wiping any dust with a tack cloth and spraying the front panel with matt clear coat. I then carefully flipped the enclosure and proceeded on other sides.

I then soldered the crossover components for which you can find the schematic in the kit purchase link. I made sure to use epoxy to glue the components on the board. Using the amazing TS-100 soldering iron I connected the wires to the crossover and placed them inside the enclosure.

Important step of the build is to seal any holes that the air inside the enclosure could leak through. I covered the LEDs with a bit of silicone to make sure of that. I also used double sided tape for sealing the amplifier plate and the battery LED panel.

Once all the components wire wired, I mounted the speaker drivers, charged the speaker using the provided power brick and gave the speaker a test.

I can honestly say that this 2.1 boombox sounds amazing. It is currently my go to speaker for everyday listening and small parties. The camera microphone that I use for testing does not do its justice but the speaker truly has some powerful bass and clear soundstage.

I hope you will give this speaker build a try and as always feel free to leave any comments or questions!

Thanks!
