The Ruinations are completed and I want to thank the following people for their assistance during the project.
Wolf - for his help with the PCD sims we'd bounced around and a starting point for the 2.5 way crossover to tweak from.
DLR - for hosting DIYNE and providing feedback on adding BBC dip while they were there.
Mzisserson -for providing feedback at DIYNE that was incorporated and verification of the final crossover.
Prior to DIYNE the tuning on the Ruinations was changed from 48 Hz to 35Hz due to my measurements making me think the 48 hz was causing a bit of a boom at ~50 - 60 Hz.
At DIYNE the speakers were fair but the tweeters sounded very sibilant while playing girl from north country fair and wabash cannonball. I thought there could be a problem in the tweeter pass prior to the DIY since I liked the Lambic's tweeter better.
After the DIY I purchased a bluegrass CD with Wabash Cannonball on it to diagnose tweeter fixes against. The ultimate fix ended up being changing the 15 uF cap to an 8.2 uF cap. This change moved the tweeter's targeted pass ~500 Hz higher when modeled in PCD.
The cap change fix got a few weeks of listening around the house before taking them to Mzisserson's house for a listening session that confirmed it was time to stop tweaking them and call the speakers done.
"The resolution/accuracy of the lower midrange down (800 or so and below) is quite amazing. From there up, it is a solid performer, perhaps a bit rolled off on top. This causes them to sound slightly dark, which is not a bad thing at all. We rocked out quite a bit and they had *****, body, and you could listen to them all day. Vocals were right on and the imaging was well placed in the room - Mzisserson"
