I placed the speaker on a stand to match the height of the left and right speakers, matched the listening distances, and matched the speaker output levels with the receiver's 1 khz setup tone. I set the center channel output to "small" on the receiver to send the bass signal (100hz and below) to the subwoofers. Then we watched sections of "Lord of the Rings" and "The Matrix" from DVDs.

The sound of the D2W center channel speaker is everything I hoped for: smooth, effortless, natural, full-range, and seamless with my left and right speakers. The D2W "disappears" as a separate source of sound. I did not need to use the L-pad to reduce the tweeter output level, so that item could be left out of the design, saving $6 and simplifying the wiring in the enclosure. And I met my budget goal anyway (see parts list).

I don't have any frequency response testing equipment; sorry to disappoint those looking for the all-important frequency response graphs. However, if any of you with such equipment live anywhere near Athens (southeast) Ohio, I'd love to test the speaker, post the graphs, and adjust the design as needed.
