Ditto! It's a great feeling to research and build something, and then find out it is exactly what you'd hoped for!

Not to beat a dead horse here, But written a page on my own website that includes most of the essential data from this project. I know I posted a directory full of random pictures before, and I'll probably remove that now, because its all here in a much more readable format. Most of the graphics should expand to full screen size on click, but its still not all that mobile friendly. Enjoy...
A linear Speaker Array you can build

No... did not use a crossover, as these are full range speakers. I do, however, use a separate "bass box" floor speaker with just a woofer, to better cover everything from about 200hz down. It does employ a passive inductor, though I've forgotten the value at the moment. As to schematics, I am sorry I didn't draw one out, as I've experimented with several configurations, including..
- 5 parallel connected groups, with each group being 3 speakers in series (this yields a 2.4 ohm impedance, and the highest power output)
- 3 parallel connected groups, with each group being 5 speakers in series. (this yields a 6.7 ohm impedance, and is the lowest power option I've tried.
- 4 parallel connected groups, with the three lower groups being 4 speakers in series, and the upper most group being 3 speakers in series. This yields a 3.7 ohm impedance, and is my medium power option, which I'm currently using. This configuration offers a little extra output to the topmost 3 speakers, which are pointed in 3 different directions, and has the advantage of projecting a little more sound toward the part of the audience farthest from the assembly.
