The 15CX1000 is a 15" – 1.4" coaxial transducer designed for use in compact reflex enclosures and stage monitors as small as 50 lt with a nominal dispersion of 70 degrees.
The low profile, carbon fiber reinforced, smooth curvilinear LF cone provides smooth response within its intended frequency range and exceptional strength, with maximum reliability under high mechanical stress.
The state-of-the-art 100 mm (4 in) LF voice coil employs our Interleaved Sandwich Voice coil (ISV) technology, in which a high strength fiberglas former carries windings on both the outer and inner surfaces. This results in a balanced coil with a uniform distribution of mass and motive energy and an extremely linear motor assembly.
A copper-shorting ring on the LF section plates has been adopted to reduce inductance and improve transient response. Hence, the intermodulation distortion figure has been heavily improved.
The neodymium 1.4" exit compression driver adopted is our ND1480 model, which has been given further thermal power handling capacity by adding high temperature ferrofluid in the gap. This has improved the thermal exchange properties even more.
The HF driver diaphragm assembly, using a high strength, high temperature treated Nomex voice coil former joined directly to the titanium diaphragm on its upper bend edge, assures extended frequency energy transfer. This improves linearity and shows unparallelled reliability when compared with a usual straight former joint.
The HF motor structure utilizes a precisely machined coherent phase plug with 3 circumferential slots. A copper ring on the pole piece reduces the inductance figure of frequencies above 10 kHz, improving phase and impedance linearisation.
A specific design has been chosen by Eighteen Sound engineers in order to maximize the cone’s profile coupling.
Due to the widespread use of high power audio systems at outdoor events, the ability to perform in adverse weather conditions is an additional key feature of the 15CX1000. This has been achieved using exclusive cone and magnet plate treatment processes which increase resistance against corrosion and make the cone water repellent.
