Housing the Be21 subwoofers is the specially produced, Utopia slope box. Although the Utopia box is similar looking to the Gen5 twin 8 enclosure, it is in fact very different and takes about double the time to produce. The enclosure is built from a 5/8″ MDF skeleton for structural rigidity and sound quality. An internal skeleton design allows for greater internal volume to be achieved while maintaining strength and reducing weight. In this design, the subwoofers are not recessed into the box, but instead raised rings are added to build and contour the enclosure around the subwoofers. Each section of the skeleton is rounded off and there are no sharp corners anywhere on the inside of the box. The outside of the box is meticulously hand sanded to result in a beautiful shape. The Utopia box is 5lb lighter than the Gen5 twin box, is stronger, and has more internal volume with less air turbulence. The enclosure is finished with gold hardware, gold terminals, and a 1/4″ layer of high density foam with upholstery that is nearly identical to the factory GTR interior. A rear centre console cover and rear deck cover is included to carry the OEM stitching from the front arm rest, through the rear console, and onto the subwoofer enclosure.

Please see the comparative sound chart below. Note that the phrasing is very generalized and the performance and sound quality are excellent for all options. There are however slight differences between the final sound of each system as a result of the different technologies that each subwoofer manufacture uses such as their cones, venting, magnets, etc.
