Fane Colossus 15XB Naked Speaker
SUB BASS DRIVER
The Colossus 15XB 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 800 Watts (A.E.S.) continuous and can cope with peaks in excess of 3200 Watts. This is due to advanced thermal management in the form of a vented die-cast chassis and motor system using an internal heatsink coupled to a large vaned heatsink mounted on the rear of the unit. These measures effectively remove heat from the voice coil resulting in extremely low-power compression. The Colossus 15XB is designed for use in 70 to 150 Litre ported enclosures.
- 1600 W Program Power.
- 99 dB Sensitivity (1W/1m).
- Versatile replacement driver for most bass reflex applications. Providing deep, warm and well controlled bass.
- Vented chassis and motor design provides efficient thermal management and extremely low power compression.
- Dual ‘spaced’ suspension system and advanced materials offers ultra-linearity, mechanical stability and superior acoustic performance at high levels of excursion.
- Heavily ribbed, fibre loaded, UK manufactured straight sided cone for increased strength, durability and performance.
- Designed for optimum use in 70-150 Litre ported enclosure designs.
- 4-inch Inside/ outside windings copper voice coil.
