The five pieces of this surround sound system are comprised of two distinct speaker designs. The front soundstage (left, right, and center), share the same basic configuration and rather unconventional crossover design. The tweeter plays quite low, so as to maximize off-axis performance while in the horizontal configuration. Meanwhile, the outermost pair of woofers are used only to fill in the lowest octaves of the speakers' playback. The outer and inner woofers are wired together in series, yielding a very easy impedance load. The rear surround speakers utilize a much more traditional MTM crossover design. They could use the same upper portion of the design that was used for the fronts, but I wanted to provide an alternate, more traditional design for those that might build and use these as standalone speakers. The crossover is third order acoustic, at approximately 2300 Hz.
