@jwcOK I was just wondering what op amp he went with I guess. It had 33079s and now? You seem to think it sounds better so I was just curious.

@jwc what was done to them?

Common Impedance Coupling. It is when power and signal ground currents share the same wire. Some of the power ground current develops a voltage that gets added to the signal input.

Calling @MetropolisLakeOutfitters Can you help this guy?

CIC

I'm too OCD or audio nervosa for that. My opinion @rplace you need a switch.

How's 'bout dis one? https://www.monoprice.com/product?p_id=7186

I just looked at the back of a R112SW. The power cord has no Ground? Is this true or is it an old picture and Klipsch has since modified? So how can this be a ground loop? Sounds more like CIC. Just get a good quality isolator and fughetaboutdit.

If you want the best quality isolator that money can buy it's simple: Go to Jensen Transformer and get an ISO MAX. No Affiliation, other than I know their stuff is good. http://www.jensen-transformers.com/product/sub-1rr/

This too has too many notes, uh huh.

This is sad news for us here on the Klipsch forum and other audio forums as well. RIP djk. 63, much too young.

Not in the area... bummer. Sounds like it would be fun. Saw Al back in the day with RTF. Awesome guitarist.

We were all treated to a demo of Klipsch's phones in Hope this year. First time I've had a pair on in I can't remember when. Nice but it's still not a LOUDspeaker. It is a different listening experience completely IMO.

Yes, yes you certainly did. Outstanding.

Actually a quote from one of my favorite movies:

First batch of new kits sold out but they don't ship until 7-31. Don't see how any Ebay offering could therefore be one of the new ones.

Too much LDS in the 60s

When running off batteries there is no 60 Hz, so no hum. The underlying problem MAY still be present but we can't hear DC

@EndoYour original post showed a parallel connection of two separate amp channels to one speaker. If these are standard amps with no provision made to be run in parallel it is a BAD idea. The proper way to run an 8 ohm load in your diagram is to run it off the 8 ohm output instead of the 4 ohm output. And of course off just one amp channel.

no. two 4 ohm capable amps tied in parallel does not equal a 8 ohm capable amp. The best outcome of this would be no damage, the worst could be one or two blown amps
