There comes a time when you just want to build the whole thing. I recently read about a DIYer who built a three way enclosures with Vifa Drivers. For space saving it would be the perfect enclosures to build the amplifier in it. Since Adam McCall got beautiful results I decided not to reinvent the wheel and build from his plans.
But why just one amplifier ?
