The Goodmans Dimension 8 loudspeaker has a somewhat unconventional design. The horizontal cross-section of the cabinet is a truncated triangle, on the rear face of which is mounted a passive radiator. The lower two units on each face are bass radiators; then comes the mid-range unit, and at the top a high-frequency dome radiator. Each of the units has interesting constructional features. The paralleled bass units use massive ceramic ring magnets mounted on a heavy pressed steel chassis. The diaphragm is heavily damped and the outer edge terminated in a Neoprene roll surround. The midrange unit is a new dynamic pressure unit with a plastic-fiber cone and roll surround, mounted in a rear-sealed plastic housing together with the high frequency unit. The high frequency dome radiator uses a doped fibre diaphragm mounted in a short acoustic coupling horn which also acts as the chassis of the unit. The eight units are mounted on external surfaces of the heavy blockboard cabinet which is finished in teak. To protect the units of the Goodmans Dimension 8, there are two snap-on panels covered with an acoustically transparent material.

The Goodmans Dimension 8's passive low bass resonator consists of a die-cast chassis carrying a thick, heavily doped fiber diaphragm with a large conventional centering device and plastic roll surround. This unit is not electrically connected to the input signal, but moves at low frequencies in phase with the parallel bass units and augments the output. Mounted on the floor of the cabinet is the crossover unit which uses four air-core inductors and four reversible electrolytic capacitors. The interior of the cabinet of Goodmans Dimenion 8 is filled with two plastic foam slabs which prevent internal sound reflections. Beneath the cabinet is a panel carrying a
