The 10W400 is a low frequency driver designed to satisfy the need for a 10" ferrite loudspeaker combining excellent linearity with good sensitivity and power handling characteristics. The transducer is primarily recommended for compact bass reflex systems in enclosures as small as 25 lt.
The paper curvilinear cone is carried by a dampened linen, double half-roll front suspension to control vibration modes. The 8 mm Xmax ensures good travel control and linear excursion. The 50 mm diameter state-of-the-art, copper wire voice coil employs same technology fitted to our top-of-the-range models, that is our Interleaved Sandwich Voice coil (ISV) technology. A high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly which, in conjunction with the highly advanced design of the magnetic structure, provides a high force factor or BL.
Another feature of our products, retained in the 10W400 are the fine air channels between the chassis back plate and the top plate of the magnet, which draw heated air out from the voice coil gap and dissipate the energy through the chassis casting.
The top and back plates of the magnet assembly have been designed to optimise flux density and BL factor in the air gap using our in-house FEA CAD facility.
