DALI, a shorter form of Danish Audiophile Loudspeaker Industries, is a relatively young company, established in 1983, but they built their name in the very demanding Hi-Fi reproduction field. Epicon 8 is the pinnacle of their Epicon series.

A bit of technical data: for Epicon 8 loudspeakers recommended amplifier power is 50 - 500 W, crossover frequency is 550/3,100/15,000 Hz, and they are bi-amping bass reflex loudspeakers with bass reflex tuning frequency of 28 Hz. However, all those numbes can't tell the whole story which is much deeper and better-sounding. The Epicon 8 delivers dramatically rich and detailed sound that captures the feelings in your favorite musics pieces and your senses. Meant to be on the floor, they are also a great design statement of the highest class.
In the Epicon 8, two 8" woofers are complemented by a 6 1/2" mid-range driver to peel away the layers of a recording and delicately separate vocals and instruments. The Linear Drive Magnet System of the woofers is complemented byd company's hybrid ribbon/soft dome tweeter module. That all translates into the largest, most room-filling sound of the Epicon family. Effectively this is a "3 + 1/2"-way" construction. Each side of the Epicon 8 is constructed from 6 individual layers of MDF, all glued together.
In the Epicon 8 these are anchored to a 63 mm multi-layer MDF backbone of the cabinet. With a thickness of 33 mm the duallayer front baffle ensures that energy from the drivers is radiated as acoustic energy, and not as vibrations in the cabinet. The curved shape of the front baffle is also a contributing factor in ensuring a stable acoustic platform. Internally the cabinet for the Epicon 8 is divided in two identical sized chambers for the woofers and one extra chamber for the midrange.
The woofer chambers are allowing tuning of the cabinet to be done identically yet completely independently for each of the two woofers. The midrange chamber allows the driver to reproduce the critical frequencies without any interference from the rest of the system. Furthermore standing waves, thanks to an organic form, are practically eliminated as there are no parallel surfaces reflecting sound waves
Thus you will find two bass ports on the back of the cabinet located as nearby the woofers as possible. Both ports are convex tapered in both ends to minimize port turbulence. At the very bottom of the cabinet, however, you will see that the hardwired crossover is mounted in its own enclosure as well, free from the dynamic variation of cabinet pressure inside the bass reflex enclosures. ■
