    Markaudio Alpair-12PW 8” Paper Woofer

     

    The Alpair 12PW is a audiophile grade paper and glass strand reinforced coned bass-mid driver. Along with its full-range sister drivers, 6P,10P and 12P, the Alpair 12PW is designed for the serious music listener. The 12PW’s relatively flat response is designed to deliver a neutral sound. The mid-high range gradually falls away above 10kHz.

     

    The development of this driver follows its full-range sister unit, the Alpair 12P. Both drivers are Semi-Free-To-Air designs, relying solely on their rear suspensions for mechanical operation. The Alpair 12PW has a reinforced rear suspension and a new coil to enable handling of typical audiophile low frequency loads (not constant low frequency loads).

     

    The 12PW has a long mechanical throw, limited by its arrestor to 8.5mm (1 way). This driver is a low-mass design, its power-train has a moving mass of 11.7 grams yet delivers a Vas of 45 litres with a total Q of 0.39, making it ideal for larger scale purist box designs.

     

    An all-new computer controlled bonding process deployed on this driver, delivering ultra tight tolerances in critical parts of the 12PW’s power-train assembly.

     

    The 12PW is primarily designed to be partnered with the Alpair 7P yet will also be a excellent partner for many tweeters. The marriage between 7P and 12PW promises much in the way of deep rich bass and fine mid-high range detail.
