HN, the master of disguise, the versatile series with an attitude. Daily Driver, SQL & Competition, they all define the B2 HN subwoofers.Using only the finest materials such as non pressed paper carbon fiber blended cones, increases efficiency & stability when cone excursion is at the most.A newly designed Â«stretch foamÂ» surround with tall roll are now used in the entire HN subwoofer lineup. As a bonus, they all feature dual stitching.With an increased powerhandling of up to 50%, all the HNâ€™s now have quad flat tinsel leads (8 in total per subwoofer).Even the motor has grown, now itâ€™s a triple slug, 8.7â€³ wide and 530 Oz, extending both xmax and motor force. The larger xmax also made us redesign the suspension.Now up to 10â€³ black nomex spiders with progressive rolls ensures the linearity of the subwoofer. In order to handle the even higher power rating efficiently, the XD Pole (cross drilled) has an even larger AFS (Air Flow System) securing the 3â€³ voice coil is kept cooler when needed. 2016 will however spawn the HN18 v3, which increases the voice coil to 4â€³ 6 layer flat aluminum (instead of twin dual wire 3â€³).The HN is now a driver without compromise, taking on any competitor in both sound quality and SPL.This is for a Dual 1ohm subwoofer.
