The General Cabinet Design The cabinet
design is a straight-forward 10 liter enclosure. I chose
to use a madisound woodstyle enclosure since it fit my
needs perfectly. The model is WS802 and I chose black oak
for it's finish. Speaker placement on the baffle is
optimized to minimize edge diffraction and it's resultant
ripple. Presented below is the front layout for the
sealed enclosure. If you wish to make it vented, simply
add a port below the woofer. For a QB3 alignment, the
port should be 1.5" diameter and 4.5" in
length. Here is the overall layout I started with. The only problem I discovered
is that the front grill frame is about 1" wide and
interferes with the woofers offset. I moved the woofer
1" from the edge to compensate for this effect. The
driver's center's and cut diameters are listed
below.
- Tweeter's Center X: 4" from inside edge
- Tweeter's Center Y: 4" from top edge
- Tweeter's Cut Diameter: 3.15" (80mm)
- Woofer's Center X: 5" from inside edge
- Woofer's Center Y: 9" from top edge
- Woofer's Cut Diameter: 5.75" (146mm)
The back input cup holes are precut by madisound for
their GB or CB models. I used no crossover circuit board,
and instead simply hot-glued the components to the inside
walls, spacing the inductors by a minimum of five inches.
