M165NQ/16 Woofer
The M165NQ/16 is the 16 ohm version that is designed to be used in paralleled pairs. These are one of a kind drivers designed specifically to be used as mid-bass drivers in open baffle applications. No other drivers are currently available that have been designed just for this application.
These new woofers have a push pull motor design that uses a Neodymium magnet on the pole piece and a ceramic magnet on the top plate. They have Copper shorting rings and an Aluminum phase plug. The phase plug, back plate, and top plate are all Copper anodized. The voice coil is a large 44mm. The cones are paper, and play smoothly into the upper ranges with no break up or ringing. And they use our popular non-resonant polymer frames. There is no better frame.
The diameter of the driver frame is 7.25" and mounting depth is 2.9375".
