Powering my OS’es and sub, I’ve got a super cheap, eBay sourced, TPA3116 2.1 channel 2x50Watt amplifier board. It’s cool looking, has more than enough power, requires just a bit of soldering to get up and running, and again, super cheap. It’s also the board that comes in many “finished” cheap amps. The one problem with this amp is that… Read more »
I was perusing the Overnight Sensation page, and noticed one of the builds that Carmody shared. It was a 5.1 where the rear speakers made use of the smaller B3N driver. These, like their brothers, are really cool looking and super cheap. I love my OS’es and I kept looking at these drivers wondering if they would sound good on… Read more »

Awesome loudspeaker animated infographic.
From the12volt.com: Crossover Calculator Crossover Definitions and Illustrations Most crossover tutorials omit information about the simplest possible crossovers: A capacitor in series with the speaker (High Pass Filter) A coil (inductor) in series with the speaker (Low Pass Filter) The first of these seems to be widely used as a quick and dirty way to protect small full range speakers… Read more »
This blog is the ongoing story of a couple of know-nothings trying to get together a few boomboxes and jamcases. Cheap chinese class-D amps. Bluetooth receivers. Cheap closeouts from Parts Express. And figuring out a bit about why it never quite seems to work as we hope. We could just write to each other in Facebook. But then again, if… Read more »
