BR on the serial rag devotees Birch Raw. In other words, everything that you see that makes it look different than a typical Klipschorn was done after it left the factory.
Your sub has an active and a passive woofer. They’re two completely different woofers.
Also, I don’t think your sub is quite old enough to be in the Klipsch museum which is the topic of the forum section you posted this in. 😉
Got my bike’s fork back from service. Unfortunately it’s been too rainy to ride but I can tell the travel and rebound is much smoother than before I sent it in.
It sure is a weird looking bike but I love it and can’t wait to ride it again!
It might have been replaced. My X Heresys have the soldered lug K-55V. It’s possible that it had that and was replaced due to the rarity and cost to replace the original one.
Looks like an F in the serial number, just look in numerous stickied threads in the forum to find what that correlates to as far as manufacturing year.
I also see what looks like C-WR-15.
