NEODYMIUM SERIES COLOSSUS 15B-700N COLOSSUS 15B-700N FREQUENCY RESPONSE DATA* +120 +110 +100 +90 dBr The Colossus 15B-700N is intended for use in high-power two-way ported enclosures and as a high-output bass driver in multi way systems. It features a 4 inch voice coil immersed in a symmetric magnetic field yielding increased linearity and lower distortion at high excursion levels. The cone membrane, manufactured from polycellulose, is much stronger and more durable than conventional paper pulp alternatives. This allows the driver to combine high-sensitivity with the structural integrity required to produce undistorted low frequencies at high output levels. The driver handles 700 Watts (A.E.S) continuous and can cope with peaks in excess of 2400 Watts. This is due to advanced thermal management in the form of vented die-cast chassis and increased motor system venting. These measures effectively remove heat from the voice coil, resulting in extremely low-power compression. The Colossus 15B-700N exhibits an average sensitivity of 100 dB and can deliver bass down to 40 Hz (-6 dB) in a 125 litre ported enclosure. +80 +70 +60 +50 20 50 100 200 1k 500 2k 5k 10k 20k Hz * Half space response measured in a 975 litre sealed box IMPEDANCE THIELE SMALL PARAMETERS Nominal Chassis Diameter Impedance Power Handling Peak Power (6dB Crest Factor) Usable Frequency Range -6dB Sensitivity (1 w - 1 m) Moving Mass inc.
