The Alumapro difference
Alumapro has built aluminum-cone subwoofers in the USA since 1994. An aluminum alloy cone stays rigid under power where paper and poly cones flex, and it helps draw heat away from the voice coil, so bass stays tight and controlled when you turn it up. Every Alumapro sub is hand built in Huntley, Illinois.
