The IQ W8 subwoofer is a masterpiece from Helix that you have to experience and hear for yourself! This subwoofer is designed for those who want the best sound quality without sacrificing performance.
The Helix subwoofer features the most robust chassis, the most powerful magnet, and a completely redesigned, ultra-lightweight yet durable 3-layer fiberglass-Mylar honeycomb cone that ensures the driver accurately reproduces every frequency.
The most revolutionary feature of the IQ W8 subwoofer is the ″Triggerable Mass System″ (TMS) introduced with this subwoofer series. This new innovation allows you to adjust the movable mass of the driver using the supplied weights. There are three weights included and they can be installed under the removable dust cup using the supplied bolt. Each weight adds 52 grams to the mass, so there is plenty of adjustment.
By adding weights, the FS, QES and QTS values of the mm element can be changed and this naturally also affects the recommended housing size / tuning frequency. The initial weight of the IQ W8 moving mass is 115g and by adding weights, you can reach a weight of up to 274g!
The IQ series basses are suitable for really compact enclosures (closed/reflex). The smallest recommended 8″ enclosure is an incredible 6L.
