3.6R crossover mods




Well it has taken me 15 years but I finally got around to swapping out the internal crossover bits with some upgrades. I already have an XM44 active crossover for the bass to mid/tweets, and no, I didn't want to go active 3-way. I have enough money in speaker cables :)

Sonic craft Sonicaps, including the platinum bypass ($$$), Solen inductors, and Neotech teflon coated OCC 20 gauge for the tweeter re-wire and 16ga for the binding post terminals. I direct soldered to the tweeter steel tabs and to the Cardas binding posts using Cardas silver solder. Nice to have the 5 cent clips gone.

For the wires at the panels I clamped the wires and one inductor under the existing rectangular tabs making sure they made contact with the ends of the wires, and then decided to melt some solder on top, so yes it looks pretty globby.(waiting for Davey to critique me ;) Not sure what else I could have done here (?) Also wondered if connecting the inductor end in the clamp is "normal".

I planned to do one side and listen to the differences, then do the other, but one of my Nord Hypex amps had other ideas. It worked fine when I turned it off, but one channel decided to stop working upon powering it back on. Looks like it's the C38 cap in one of the SMPS1200A700, which is bulging. I love the sound coming from the these Hypex NC500 units but they sure aren't reliable.

So I did listen for a while, just using one of the amps powering the mids/tweets, and I do hear differences but it sounds like #$@$ without the bass panels, so decided to just do the other speaker. Break in and serious listening will have to wait to get the amp fixed, or wait for a different VTV I just ordered; whichever comes first.

Looking for constructive feedback on my first crossover work ;)
