The Decware Wicked One is a compound horn-loaded dual bandpass design where each half of the box shares the same horn flare. This makes possible bass that would normal require a box almost twice as big.

It's fast, and deep. And can be made into a coffee table for your home or a seriously dangerous box for the car.

HOW TO BUILD ONE YOURSELF

SKILL LEVEL: This is an easy box to build provided you have a good table saw and can make accurate cuts.

TOOLS NEEDED: Besides a table saw (with sharp blade) you will need clamps, carpenter's wood glue, a sander (belt sanders work well) and a drill.

WOOD NEEDED: The box can be built from 2 sheets of 48 x 96 inch plywood, MDF or high density particle board.

SCREWS are typically only used to fasten the removable top (lid) so that the woofer can be accessed. If you properly build the box with wood glue and clamps, nails are not needed as the glue becomes stronger then the wood itself. If you have an air nailer, you can use 2 inch finish nails to hold the panels together in place of clamps while the glue dries.

FINISHES: The most common way to finish this cabinet is to paint it. There are tons of finishes available that can make the box look like anything from rock, to marble. Also you can use real wood veneer for a completely professional look in the house.

JOINERY: The quality of your cuts determines the joinery or fit of each panel. Quality joinery is a major part of the distortion free performance of this box. If you're into box carpet and liquid nails to hide your joinery, and demand the best performance consider purchasing one already built by Decware. We use CNC machines and build the cabinets more perfectly then is possible to do by hand.

WIRING: Since this box can be pointing in any direction other then face down, no official back or front have been defined. We recommend soldering a pair of stranded 16 AWG copper wires to the woofer terminals and run the wire out through the port opening. Make it long enough to connect directly to your amp. If you decide to hide the wire, you can drill a small hole through one of the sides of the box and seal the wire with caulk where it passes through the hole. Terminal cups leak air and are not recommended.
WOOFERS

The "Wicked One" is one of those rare boxes that works across a wide range of drivers. The biggest difference being how low the box will play. The ideal woofers are those designed for box sizes between 1 and 4 cubic feet with an fs around 30Hz +/- 10Hz.

While you can use 4 woofers, it won't make the box much louder, just lowers distortion at max output. Most people use 2 woofers in the Wicked One.

You can find out what other people are using in our support forum for the Wicked One!
The chart above shows the SPL response potential for a pair of 10" Rockford Fosgate woofers (RF108's) in an ideal 4th order enclosure of 10.01 cubic feet. The response is indicated by the blue line in the chart.
Using the same woofers, the response was measured after installation into this dual band pass horn. The results of that are indicated by the red line in the chart.

The yellow area represents a serious gain in efficiency between the two enclosures. The dual band pass enclosure is also smaller in size by 1 cubic foot.

This illustration is very conservative. By watching the impedance vs. frequency response of a ported box it is easy to understand why a properly sized and ported enclosure will offer increased power handling at the frequency of that port...

But, the way this horn loaded design works is similar to having several ports working at several frequencies. We call it "a rubber throat" because the "port" if you will, or better spoken- "the mouth" of the horn changes in size and length depending on the frequencies it reproduces. I know this is hard to follow if you're not up on horn loaded enclosures so just remember the following:

A port resonates at a given frequency determined by the length and diameter of the port, while a horn resonates at a HI frequency and a LO frequency and EVERY frequency between the two. For this reason the woofer is dampened at every frequency between LO and HI. That's why it has such phenomenal accuracy, gain, and bandwidth.
Note: This box design and the unique plans create plot points that you can then adjust to different depths. For example; the box is 36 wide, and 13.5 inches high, but the depth can be adjusted anywhere between 24 and 36 inches. That's one of the magic features of this box, so you can fit it into your application. Remember, cramming a box into a space barely larger will only choke it off and tank performance. Better to make it smaller and let it breath.
