Experimenting with reversing polarity to speakers

Using a single pair of Clear Day double shotguns terminated with bananas feeding Totem Forest speakers. Am using Audioquest’s diagonal connection recommendation for bi-wireable speakers (see page 4 at link below;

"Using Full Range Cables On BiWire Capable Speakers"). Jumpers are also Clear Day wire.


Came across some comments on the web about experimenting with reversing the polarity of speaker cables at BOTH speakers...i.e., connecting red to negative and black to positive. Am NOT talking one speaker out of phase w/respect to the other. Both speakers are in phase with one another.

Having made the change, I did think stage depth immediately increased and imaging focus was improved. The improvement was on the order of installing better cabling, I’d say. I am NOT asking for explanations for the effect. I started the thread merely to suggest an "experiment" to those that might not have considered it before.
Cheap fun.

This topic has been discussed previously on A’gon and EXTENSIVELY in the 2010 thread below:

I readily admit it could be placebo (i.e., my imagination). Another well-regarded explanation relates to countering the effects of "out of phase recordings" (See Clark Johnson’s, The Wood Effect discussed at length on the Steve Hoffman forum and elsewhere). BUT the effect does seem to me to persist across multiple recordings (listening to various ripped CDs played off hard drive through Aries Mini>>Gungnir DAC>>Preamp>>Amp).

I’m inclined to think it’s related to some kind of room interaction and distance to listening point. More listening is needed to decide how consistent the benefit is. Of course, whatever the reason for it, the proof of it being a real improvement will be switching back to "proper" polarity after a few days and hearing a degradation in sound quality.

Best regards.

To expound on Geoff's good point, another fact making absolute polarity moot is that the signal on each track of a recording made on a multi-track recorder may or may not be in the same polarity as any other. That’s one reason many recordings bear no semblance whatsoever to live music. Listen to Dwight Twilley's first solo album, or Tom Petty & The Heartbreakers first. They were both recorded at Shelter Studio in Hollywood, by two of the most incompetent engineers ever let loose in a studio---Max and Noah, whoever they are (were). Severe phasing problems on both albums---the sound actually "swirls" around.
I agree with Stereo 5. I use Cary SLP 98 P, and Cary suggests reversing polarity at speaker terminal. 
Is reversing polarity at tube amplifier output terminals identical in effect to reversing polarity at the speaker input terminals?
Yup. If you think about it, it has to be---both ways does the same thing, and neither the amp nor speaker cares.
Just make sure you turn the amplifier off when experimenting with the speaker wires. It makes a bad day if/when they touch each other by accident.
