"But the upgraded H290C waveguide benefits from an upgraded crossover that has different values in a couple locations. Its impedance curve is different, necessitating the removal of capacitor C1 and installation of 16Ω resistor Rs. Check the schematic and board layout to identify and locate these components."

I slept through, as I have been doing since high school Very Happy

, the technical details of the H290C and installed them without changes to the boards. Even before the crossover change I could hear an expanded soundstage in general and clearer exposition of the minor themes of a musical score. When I woke up and corresponded with Wayne I added the Rs resistor that softened the mids. Further discussion revealed that I also had to snip C1.

Once done, and liberally covered with rope caulk, the H290C are better-sounding than the Eminence: tonally more neutral with a clearer presentation of nuances like Violas under Cellos and brushes on Cymbals

Speaking of Violas:

What's the definition of a minor second?
Two violists playing in unison.

What's the definiton of "perfect pitch?"
Throwing a viola into a dumpster without hitting the rim.

Why do violists stand for long periods outside people's houses?
They can't find the key and they don't know when to come in.
