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:
https://forum.audiogon.com/discussions/polarity-mystery-can-you-help-me-solve-it?highlight=sound%2Bi...

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.

The few times I have experimented with reversed polarity I noticed a change in bass but I could not hear anything different in the mids and highs, at least in my room.  You might want to disconnect the subs when doing the polarity tests.  Trust your ears and leave it whichever way sounds best to you.
If you are using a tube preamp, many of them reverse polarity at the output and compensation must be made by doing exactly what you did..  All 3 of my various Audible Illusions Modulus series preamps and my Rogue Audio RP-5 are inverted at the output and I had to reverse both speaker cables.
Taken one step further, especially with vinyl, the album itself may be out of phase. 
jc - easy enough to take the subs out of the picture via their on/off switch and evaluate polarity changes on the Forests only.

stereo5 - Yes indeed. I am using a tube preamp (Opera Consonance Ref. 50) as part of the current configuration. Is polarity reversing something you can ascertain from specs? Would be interesting to confirm or refute that idea for the Ref. 50. However, since the subs are getting signal from the Forest speaker posts (not from pre-amp outs) any change in polarity at the Forests should "carry over" to the subs too - I would think.

Regardless, since putting the Forests back in service and using the subs with them for the first time, I’d been slightly dissatisfied with the sound (compared to from these subs w/Prelude Plus floor standers). Not a forebrain-type recognition of a problem - more a sort of nagging impression after a listening session that things just weren’t as clear or focused as they might be. Since reversing polarity that little bit of (lower mid-range?) "muzziness" is completely gone. Listened to a variety of music today and things sound nice and coherent across the frequency spectrum.

Thanks for the input folks. Again, my main purpose in starting this thread was to give some visibility to yet another "tweaking" option that’s easy, free and low risk (assuming you turn off power before switching speaker leads) but has the potential to provide some real improvement to a system’s sound.
