Overview

Adire Audio 12KH501D2 12" Subwoofer

Adire Audio 12KH501D2 12" Subwoofer

A great solution to ground-pounding bass without breaking the bank


The new KH501 series subwoofers have deep rooted design history allowing you to experience every subtle nuance of the bottom octaves along your sonic journey. With top shelf materials, design and engineering, Adire has made world class bass-on-a-budget possible. 

The KH501 features a FEA optimized, triple stacked Y35 ferrite motor structure which provides superior Bl force to get its 2.5" round copper wire voice coil swinging for the lowest octaves, while still allowing it to have ultra-transient response and maintain a warm, tonal balance. 


The spider landing is mechanically bolted to the steel frame which allows for the ultimate durability and longevity of the driver, while the progressive roll of the spider helps to maintain linearity in all kinds of install applications at the highest excursion levels. The heavy-duty tinsel leads are stitched into the spider to negate lead-slapping. 

The rigid kraft pulp fiber cone and multi-layer foam/rubber surround ensure long lasting dependability in the harshest environments, while the lightweight glossy carbon fiber dust cap adds immense stiffness to the cone while adding very little mass.

The Adire KH501 series subwoofers are designed to handle abuse and are built to last, all while providing crystal clear low end that shakes the neighborhood, regardless of your musical tastes.  With integrated rubber gaskets, oversized spring loaded terminals and over-engineering throughout, these are the last stop in a budget minded installation that will still make heads turn.
