The local company Cube Audio is known for full-range speakers way outside of the mainstream and its founders – Grzegorz Rulka and Marek Kostrzyński – have been very effective in popularizing these niche exotic designs in recent years. So much so in fact that their rooms at various shows are usually packed. It’s no mystery why that happens, however. There visitors witness for themselves how passé the usual widebander stereotypes actually are, Cube Audio products stomp on them hard by making surprisingly gutsy wholesome sound from modestly styled and sized enclosures. More importantly, just one unassisted driver per box so successful in pulling this off turns widebander naysayers into a devout converts as easily as it gains friends among the non-audiophile audience not familiar with its orthodox kind. Although very purist by design, Cube Audio speakers are admirably easygoing, quite casual even. That makes them very special.
