15NB451 loudspeaker combining good linearity and efficiency with high power handling capabilities, with use of 77 mm voice coil and double spider. It features aluminium die cast frame with integrated demodulating ring and vented neodymium magnet structure. The massive heatsink improve the cooling of the magnet structure, which reduce power compression. 15NB451 is suitable for application in a wide variety of enclosure types and particularly as LF driver in 2- or 3- way boxes.
