HUMAN K-101 Speaker Kit
$376.00 / pair

Building speakers based on classic designs:
EPI 120; Genesis 110
(back to kit/legacy projects)
See the gallery of projects below

The HUMAN K-101 (pronounced "Kay-ten-one") is a kit to build a ten-inch two-way speaker, similar to the EPI 120 (which had a few slightly different variations, all very similar, including the Time/Energy 120) or the Genesis Physics 110.

The crossover used by EPI is just a single ten microfarad capacitor (I'd recommend using a high quality film type capacitor) in series with the tweeter. The Genesis I used a 6.8 uF capacitor and a shunt coil of 0.63 mH, a "second order" network, intended to decrease the power "seen" by the tweeter below the roll off frequency. Since this comes with a penalty in the linearity of the phase response, I prefer to use the single capacitor design myself.

The K-101E is a special edition of this kit, intended for rebuilding a pair of EPI 120 speakers. The tweeter is built on a 5" diameter faceplate (the PRO 002 ME1), and the input terminal/crossover/wiring assembly is built on a board that is screwed inside the rectangular opening in the original cabinet (the ACC 004 A).

The K-101G is similarly a special version, intended for rebuilding the Genesis 110. The tweeter is built on a 4-7/8" square faceplate (the PRO 002 MG), and the input terminal/crossover/wiring assembly is built on a board that is screwed inside the rectangular opening in the original cabinet (the ACC 004 A).

Details:

Interior dimensions in inches, volume in cubic feet:

Genesis 1102612.591.7
EPI 12023.513.5112.0

My calculations based on measurements of the PRO 031 woofer show that a sealed box of about 1.2 cubic feet can be used very satisfactorily. The larger cabinets used in the above models would underdamp the low end a bit, but not radically so.

Stock bracing: None. I recommend adding at least one brace front to rear at the point between the woofer and tweeter cutouts.

Driver position: Offset from center of cabinet face, tweeter a different distance from the top than the sides, drivers as close together as practical.

The HUMAN 101 Kit includes:

2 PRO 031 woofers
2 PRO 002 M2 tweeters
2 Terminal cups with gold plated 5-way binding posts
2 Complete wiring harness/crossovers
Screws to install all parts
Pegs and sockets for grill mounting
Basic instruction sheet (and telephone/email support)

You provide:

The cabinet
The grill, if desired
Internal damping material (e.g. fiberglass, polyester, etc.) -->
