Following the successful incorporation of carbon fibre cone technology in the Carbon Pro Series, ProAc have been researching other materials for possible inclusion in their high end loudspeakers. The results of this research have come to fruition in the shape of the new K series which utilises cones manufactured from the material, Kevlar.Kevlar benefits from having similar properties to carbon fibre, being light and at the same time rigid. The ProAc 6 1/2" drivers utilised in the K6 feature Kevlar cones made by the same special method as our carbon fibre coned drive units; the cone is painstakingly produced from a mould by hand, a labour intensive process taking many hours to complete.
Although Kevlar has proven to be an excellent cone material sonically, the Kevlar ProAc bass drivers require a different porting mechanism in order to realise their full potential. The bass is loaded by an almost invisible vent to produce a wonderfully weighty but exceptionally fast bass response. These drivers are seamlessly crossed over to a 2" dome midrange, the horn of which is manufactured from billet aluminium and for the high frequencies, ProAc's proven ribbon tweeter has been chosen.
