It features a 3-way bass-reflex design and 4 drivers: 1x 1-inch soft dual-diaphragm tweeter 1x 7-inch paper mid driver 1x 10-inch high-rigidity Aluminium alloy bass driver 1x 1-inch soft diaphragm tweeter at the back The Reference 18 cabinet is made of multi-layered wood for its excellent stability and strength and to effectively absorb and disperse resonances. It also features the oval cabinet design of the flagship Divini Illusion speakers with precision-calculated internal reinforcements to further mitigate the effects of vibrations and resonances.
The Reference 18 also features Divini's patented suspended design in its tweeter design.
