Markaudio Alpair-7P 5” Full Range Paper Woofer Matched Pair
The Alpair 7P is a audiophile-grade paper and glass strand re-enforced coned driver. Along with its sister drivers, 6P,10P and 12P, the Alpair 7P is designed for the serious music listener. The 7P’s relatively flat-wide response is designed to deliver a neutral sound. The high range life response is moved to begin its elevation above 17kHz.
Particular attention is paid to the stability of the light-thin cone with bonding reinforcement being deployed on the inner contour of its profile. The 7P’s moving mass is a lightweight 3 grams, yet it retains a long throw operation @ 4mm.
An all-new computer controlled assembly bonding process is deployed on this driver, delivering ultra tight tolerances in critical parts of the 7P’s power-train assembly.
The 7P can be used as a single-point source driver in purist Full-Range applications, or to partner with the Alpair 12PW, a bass-wide version of the Alpair 12P. 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
Running In: First 100 hours low volume background mixed music, no heavy bass. Gradually increase to normal operating levels from 100 hours onwards.
The 7P is a “light duty” driver. Max throw = 4mm (1 way) limited by Arrestor.
Keep the cone surface away from direct sunlight or any UV source.
