The All-Dayton category could in theory have someone showing up with a giant WMTMW with 8's and 10's and whatnot, which would be an odd comparison to a 2-way bookshelf design. I know it's about sound quality... but I tend to think people listen to music with their eyes more than their ears sometimes.
          I just figured out that I have a family reunion that weekend. I'd ditch them for MWAF but this part of the family only gets together every 5 years-ish. Kinda disappointed...

            The Defiants - InDIYana 2019 Bare Minimum Competition - Final Writeup

            So what's next from here? I will be doing some vertical off-axis measurements to accompany the horizontal off-axis measurements that I detail in the report. I will also be doing some A-B testing with an additional 1.5ohm resistor after the 20uF capacitor in the LF circuit to control the woofer knee. I tend to like relaxed midranges, and the current 5 part XO measures much more flat than relaxed. I don't find the current XO objectionable at all with 5 parts... I just think it might be that much better with a 6th component. Time will tell.

            Otherwise, these bad boys will be going to Midwest Audio Fest in July! I hope to see you guys there!

            Thank you so much for following along with my build and learning with me. The interactions are what make the build logs all worth it.

            Wow. Cool 36 page pdf write up. Good looking horizontal polars, CSD and toneburst plots. Very detailed. Must have taken a long time to put this all together! Good job!

            So, looks like we are all getting ready for a re-match in Springboro! I will be in the <$200 category as well.
