The housing is machined from one piece of aluminium, anodised against corrosion, and made in Ireland. Three interchangeable cables cover 3.5 mm unbalanced, 2.5 mm balanced and 4.4 mm balanced.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003ch3\u003eA single 7mm TrueResponse driver\u003c\/h3\u003e\n\u003cp\u003eOne full-range dynamic driver covers the whole band, so there is no crossover and phase coherence comes from the structure itself.
