HUMAN K-81G Speaker Upgrade Kit
$363.00 / pair

This is a complete kit to rebuild any of the Genesis Physics eight inch two way systems - the I, 1+, 1, 10, and 11.

Genesis I
Genesis 1+
Genesis 1
Genesis 10
Genesis 11
PRO 005 woofer
PRO 002 MG tweeter
ACC 004 A crossover

This upgrade will turn your aging classics into the best possible version of what they can be.

The woofers feature sealed cones (as used in later models) and butyl rubber surrounds (only seen on two of their top-of-the-line models). They also incorporate some internal improvements to further increase linearity,

The tweeter uses my aluminum concave dome for lower distortion and more extended high frequency response.

The backplate/crossover assembly features audiophile-grade components and 16 AWG oxygen-free wire. The new rear connections are gold-plated five-way binding posts.

The HUMAN K-81G includes:

The Genesis I, 1+, 1, and 10 all use the ACC 004 B second-order crossover assembly which is mounted on the terminal board and screwed in (fairly easily) from the inside of the cabinet.

The Genesis 11 requires that you tell me what terminal arrangement is installed in your cabinet so I can match it. Most of them use a round cup that fits a 3" hole, with the crossover parts mounted on it.

The crossover I use in the HUMAN 81 and 81+ is just a single ten microfarad capacitor in series with the tweeter (as shown in the image above). I can build your kit this way if you prefer.
