The Colossus 18XB is intended for use as a high output sub-bass driver either singly or in multi-way systems. The unit features a 4 inch ‘sandwich’ inside and outside windings voice coil, immersed in a symmetric magnetic field, and centralized by using two suspensions in a dual arrangement to maintain ultra-linearity and stability at high excursions. The heavily ribbed straight-sided paper cone membrane is reinforced with high-strength composite fibres to resist deformation under extreme loads. The driver handles 1000 Watts (A.E.S.) continuous and can cope with peaks in excess of 4000 Watts. This is due to advanced thermal management in the form of a vented die-cast chassis and motor system using an internal heat sink coupled to a large vaned heat sink mounted on the rear of the unit. These measures effectively remove heat from the voice coil resulting in extremely low-power compression. The Colossus 18XB is designed for use in 100 to 250 Litre ported enclosures.
- Deep, warm, well controlled bass reproduction.
- High BL factor 25.9 T/m.
