Building speakers based on classic designs: HUMAN C3 If you're going to use a center channel speaker in a high powered Home Theater system, it should be a very good one, and complement the quality of your main speakers, as well. The HUMAN C3 is just such a speaker. Using two of my hand built woofers, a carefully selected midrange, and one aluminum concave dome tweeter, it has great power handling, frequency response, and clarity. The drivers are shielded to prevent video interference. I build the box to be able to act as a TV stand, wide and deep and strong, but you can make it any shape that works for your setup. The crossover used in the HUMAN C3 is designed to roll off each driver with a fourth-order slope, preserving phase at each transition. High quality film-type capacitors are used everywhere in the signal path, as are air-core choke coils. The coils are arranged at mutual ninety degree angles to each other to prevent inductive interference between the signals passing through them. The parts are mounted on two separate boards, one for the woofer crossover and one for the midrange and tweeter, with their own input wires to facilitate biwiring or biamping. Details: Interior dimensions in inches, volume in cubic feet:
Stock bracing: I like to use several vertical braces scattered irregularly about the cabinet, from top to bottom. Two of them go against the front panel between the midrange and tweeter and each of the woofers. This increases rigidity tremendously, reducing panel resonances and making the speaker an even better TV stand. Driver position: The midrange and tweeter are centered vertically and placed one above the other in the front panel, with the woofers centered vertically on each side of them, about an inch away. The HUMAN C3 Kit includes: 2 PRO 006 woofers - magnetically sheilded
You provide: The cabinet
