The use of copper tubing allows to drain interferences and this is why we used the third long leadout. It's connected only to the casing, having no contact with the signal transmitted by the resistor. The third leadout should be joined to the ground or "-" speaker input.

Here a pic of my x-over lets start there.


So the 2 short wires connect same as the resistor now, the long wire goes to?

The 2 short wires on the Path audio are your leads, just like on any other resistor.  The longer, more flexible wire is a shield drain.  You can connect it if you want to, but you don't have to.  Supposedly it's a little more quiet, if you connect it.  I connected mine to the negative wiring in the crossover.

Thanks, I'll give that a try.

Mike, I see you have Jupiters bypassed with the Miflix caps.  I've been thinking about bypassing my Jupiter caps too.  How do they sound?  Was it a noticeable improvement over running the Jupiters without a bypass?

I had Sonicap Platinums as bypass caps before. The Miflix were a definite  improvement, more detail and more dynamic. I think you'll like the difference.

As you know with these speaker every change can be heard.

I found some pure silver speaker wire in my storage closet and decided to use them for the subs on my Super 7s.  Ordered some new speakOn connectors that had gold plating instead of the steel connectors I had before. 

Got everything in and assembled today.  Hooked it up and.... wow, the lower mids are MUCH clearer and way better integrated with the mid panels. 

It was a bit surprising how much affect it had on the mids, but then again considering how high the subs play up to, it actually makes sense. 

Anyway, lesson learned - the cabling on the subs matters.  If you have generic wire on your subs, try out something better, you might be surprised!

Are your silver cables solid core or stranded?  Also, what guage and insulation type?  Just curious. 

I was considering wiring mine with 3’ runs of Kimber 12TC.  Well, I was when I was working.  Have to find a job before I can do anything new to my rig.

Burning in some of the new copper caps being offered at GR Research here.
Started with the  high pas  filter, have them bypasses with  Miflex  coppers as well.
Getting close to 100 hrs, letting them  play continuously.
Could hear the potential right  out of the gate, more dtail  and depth  but   they were "crsipy" , not overly   enjoyable.


Seem to be improving  quite  a bit now... need some more hours

Solid Core.  16ga I think.  Based on listening tests, I've not lost and volume or extension going from 12ga generic copper to 16ga pure silver.  I'll pull out my FFT analyzer and run some test tones through the system this afternoon to confirm.

I had that style copper cap in the midrange and tweeter position for a long time, and recently bypassed both of them with small Miflex caps.  As great as the big pure copper caps were, using the Miflex to bypass them DEFINITELY improved clarity and focus, particularly in the lower mids.

Built a new crossover. More detail is the immediate result. Have to get some hours on it now.

Jupiter capacitors, Miflex bypass capacitors and Jantzen inductors.

I could never find those large gauge Jantzen wax foils in stock anywhere.  I ended up going with some Mundorfs.

Today I have received the Miflex KPCU-01 0.022uF that I want to use to replace the styroflex that I added in my small coaxials. And Mills 5 watt resistors.

The current bypass was an improvement, I hope that these expensive Miflex are another. If not, I will also say so.

Parts express will special order any value you need.

I ordered from hificollective in the UK. 4 week wait for the 1mh and 3mh. Ordered in July and finally got around to putting it together last week. Too cold now to do a second coat of paint. Then I need to screw down the drivers tighter.
