The M-165X with the XBL² motor

Like the M-130, the M-165X has a curvilinear shaped treated paper cone, allowing a smooth extension into the higher frequency ranges.

This woofer has incredibly smooth midrange and very good low bass extension. -3db down point in a 1.2 cubic foot ported enclosure is 37.5Hz.

The XBL² Motor structure lowers low frequency distortion by keeping a linear BL even at high output levels. X-max is significantly increased as well.

It also uses a polymer frame featuring venting beneath the spider plus a vent pole piece.

This driver also works great as a mid-bass woofer in an open baffle design.

The diameter of the driver frame is 7.25" and mounting depth is 2.9375".
