For anyone interested in dipole subs such as the Gradient, there is one now available that is really special. It is an open baffle/dipole subwoofer that was developed in collaboration between Danny Richie of GR Research and Brian Ding of Rythmik Audio. It features two 12" woofers mounted in an open baffle H-frame, powered by the Rythmik Audio Servo-Feedback amplifier system. Those components are offered as a kit, with the plans for the H-frame posted on the GR Research website. Danny has a woodworker in Canada CNC-machining the frame out of 1-1/2" thick MDF! You can paint or veneer the MDF (or have it done for you), then install the components in the frame. The resulting performance is exactly the kind of bass that dipole speaker owners (ESL, Magnetic-Planar, Ribbon) desire---no boom, no bloat, just lean, clean, low bass. Read all about it on the GR research website, and look for the kit on the Rythmik Audio site.
