It's summertime, the weather is nice, and with the recent
craze in portable audio devices, what better time to build a
DIY portable speaker system? But since we're talking DIY
here, there's no need to conform to industry expectations;
forget the ultra-miniature, micro-sized speakers and boomboxes
that don't play very loud and feel like they cost about
three dollars to build. I want a speaker that is portable
and that plays loud enough and long enough to be used
outdoors at a family reunion, ball practice, or the pool.
I will warn readers in advance-due to the amplification
and electronics aspects of this project; it is somewhat more
involved to construct than it may look. Not that the wiring of
the amplifier and battery system is overly complicated, but
it does add some complexity. Also, the extra sub-enclosure
for the battery and amplifier, as well as the input and output
dish construction does require a bit of attention to detail.
