Our dual APR10 passive radiator kit offers the ultimate in deep bass performance from our SDX10 subwoofers. The well-braced enclosure and passive radiators with 5 washers (225 g added mass) tune the SDX10 to 23 Hz. With an 80 Hz low pass filter you will have an f3 of approximately 22 Hz. With the included panels, you have the ability to make a separately enclosed area for a plate amplifier of your choice. Amplifier cutouts can be made with a simple jig saw.
The enclosure is made of 1" thick sides, top, back, and bottom. The front for the subwoofer cutout will be 1.5" thick when assembled. All bracing is 1/2" thick and interlocking. This makes for an extremely dead and heavy enclosure. 18.5" x 18.5" x 18.5" external dimensions.
The kit comes with the following:
1 x SDX10 Subwoofer
2 x APR10 Passive Radiators
1 x 2.2 ft^3 Flat Pack Enclosure (2.0 ft^3 with optional internal amplifier chamber)
