Markaudio Alpair 12PW Wide Range (Woofer version of Alpair 12P)

High Efficiency Paper Cone Wide Band - Generation 1 Audio Driver

Link to pdf file specification sheet download

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. 

Alpair 12PW + Alpair 7P Plans

Suggested box Alignment:

45 liters (1.6 cubic feet) with 10% polyester fiberfill.  Use a 3" diameter vent by 7" long for a 3dB down point of 38Hz.  I'm sure there will be other box suggestions online too, try searching for Alpair-12PW at to see what other people are doing with this driver.  There are also some discussion on pairing it with some full range drivers like the Alpair 7P.

Great wideband mid bass
Quite an unique midbass driver, being based on a full range unit means it's fairly easy for beginners to design simple crossovers and achieve decent results. The cone profile is very shallow, meaning you cd get away with crossing a little higher than normal for a 7"

Other positive aspects are decent bass, good transients, sensitivity and very clear mids.
Currently using with a viawave ribbon tweet, still voicing the crossover. It's a great combination imo

One thing to watch when designing the x/o is a slight frequency bump around 3khz.
