Talk: 8 Things I Wish I’d Known About Polyamory (Before I Tried and Frakked It Up)

This belonged to my wife's grandmother. We found it stashed in the attic of her parents' home. My daughter for scale. The paper cutouts were for a design I eventually abandoned - a more complicated 2.1 sound system with MTM layout and a subwoofer in the center. The kind folks on Parts Express TechTalk forum talked me out of such craziness.
As part of MAC’s popular Tech Talk series, four leaders of Atlanta’s hottest startups discussed how their companies help generate leads and new sales by using the newest technology. Jeff Hilimire of Dragon Army moderated the startup panel including Jon Birdsong, Rivalry, Kyle Porter, SalesLoft, Eric Spett, Terminus and Adam Steinberg, Baserate.

I had never designed or built a crossover before. Chris Roemer on the TechTalk forum basically did all the calculations and walked me through what I needed to do.
In his words:
"So we put a "Zobel" across the 8" terminals (an 8ohm resistor and a 10uF cap - an "npe" is fine here) which pulls its impedance at 20kHz down from 160ohms to 8ohms. That lets you get by w/a relatively small (1st order) coil. Use a 0.60mH #20.
The tweeter needs to go 2nd order (a big reason why is that it does NOT have "ferrofluid" and hits 27ohms at Fs). You need a 3uF series cap and then a 0.40mH "shunt" coil (to gnd). Between that filter and the tweeter we need an "L-pad": SR = 4ohms, PR = 12ohms.
This crosses around 3.5kHz. Shouldn't sound too bad. Looks like the worst "artifact" is about a +3dB "hump" around 800-1000 cycles which is inherent in the 8"FR's response."
