This design is inspired by Marshall speakers and it delivers great music and sound quality.
I had an old bluetooth speaker lying which was made an year back but, I was not liking the front grill/speaker holding piece which exposed the speakers and the design was not very appealing.
I stripped it completely and since I missed the old blog post on how I made them, lets take you through the complete steps involved and how we have made this .
Materials Required The inventory or BOM(Bill of Materials) required to build such a speaker at home is as under
a. Wood/MDF/Ply to make the outer casing or body of the speaker. I chose planks of
Deodar wood already lying in my garage to build a box that would be sufficient to hold
the amplifier PCB and two 4 inch drivers.
b. Amplifier PCB I chose a SANWU make TDA8932 BT PCB available on Amazon.in
and it delivers amazing output from 10 volt to 36 volts DC.
c. Power Supply The most prudent choice would have been a Li ion battery pack
either 12/15 V managed by a BMS(Battery Management System) , but since I intend to
use it indoors, I chose a 12 V DC SMPS (2A) to run the amp.
d. Drivers I bought a pair of JBL A-140 4 inch drivers from Amazon for this build,
based on the reviews and the output power deliverable by them. (22W RMS per
speaker).
e. Jute Grill I made a frame and bought half a metre golden jute cloth from a sofa
maker for the purpose of making the speaker grill, stapled it in the correct way from \
inside and stuck the same with a pressure stapler.
f. Miscellaneous Basic tools like screw drivers, soldering machine, connector wires,
jumpers, heat shrink sleeves, pliers , angle grinder, golden inlay (for designing grill), wire
cutters, nose pliers and some DC jacks.
PS: I am obsessed with the design and the photos. Sharing some final build pictures. Press the heart if you like it !!
