Out-Of-Phase Speakers

[highfigh]

.....HighFigh, I apologize for not seeing this one earlier....I would really appreciate your doing that measurement....will be glad to send you a sawbuck for your efforts....

Patience, Grasshopper.

8ohms is 8ohms weather in phase or out.

+1

Most subs have this function built into it... So you can measure that, But I'm sure it will be the same...

.....Joe, thanks for the response, but I believe you're talking about a phase-control adjustment on the sub....I'm talking about what is "considered" to be improper reversed wiring at the speaker terminals on the back of the speaker enclosure.....

Well then I'm confused. There is only two ways to connect it.

If you think about it, there really isnt any wrong way to wire a speaker. As long as you keep it constant throughout your installation everything will work fine. The only question would be, would you rather have your speaker pulling or pushing, because that is the only difference between the two when you reverse polarity. And if you have ported speakers, as it will be pulling air in instead to pushing air out. The speaker surround has movement in both directions...

For one this is the only Alternating Current that will have polarity.

I bet you couldn't strike that pose with the old knee.




Don't certain manufactures intentionally wire one of the drivers out of phase to achieve a certain sound signature. (I seem to remember reading this somewhere. The auto calibration on some receivers read the speaker as being wired out of phase when it is actually correctly wired.) I wonder if your speakers are this way.

.....STRONGBADF, I just got my Daughter a used pair of Vandersteen 2CI'S, really good speakers, great low-end....the 8 inch woofer on the front, and the 10 inch "active" radiator on the back, share the same air-space, with the 10 inch element wired out-of-phase, would have to be....their claim is the 10 inch is "mechanically coupled" to the 8 inch woofer....whether the 10 inch woofer on the back is powered or not, I'm not sure....I would have to remove the all-encompassing grill cloth to check, so I won't....here's shot of what's inside the Vandersteen 2CI's.....

.....Joe, I assure you, the sound-quality is "markedly" different when you cross-wire at the speaker terminals of a full-range speaker....feel free to cross-wire any of your full-range speakers to experience what I'm talking about, it doesn't hurt them at all....crap, I had 4 full-range speakers cross-wired for about six months kicking them with Crown K2's.....

.....if some of you Guys have speakers that are noticeably bottom-heavy even with the bass tone control at flat, you need to try cross-wiring them....you'll probably want to keep them that way.....

I was not disagreeing with you. I agree 100%. I've done it many times...

When I was a kid I hooked up a 60Watts bulb, just to see what it will do... amazing! lol

.....Joe, I'm curious, what effect did reversing the current-flow through the light bulb bring?.....

Silky smooth, chocolate like lighting bathed the middle of the room while an edgy white light illuminated the corners in a very pleasing contrast.

I'm really looking forward to the 'makes sense' answer. Stuff has to make sense to me.

Pulsating light... More bass, more pulse... But that works either way, in phase or out..

.....ya' better just give half of one, Alex .....

.....don't hold your breath, it doesn't make any sense to me, either....I guess we'll just have to wait on HighFigh to enlighten us.....

.....isn't that what he said?.....

 

[Alex2507]

.....isn't that what he said?.....

" ... the back half."

That's the punch line to an old joke. I'm just guessing that you might know it.

.....Alex, I was jokingly implying you were floating around tree-top levels from some kind of pill....so I said just give me half of one....tell me about the back half joke .....

.....EDIT....on second thought .....

I have a pair of KEF IQ8DS speakers - two matching concentric drivers on either side of an angled enclosure, wired out of phase with each other, and yet each speaker is rated at 8 ohms.

So, ‘splain that one

.....CraigV, do the two matching concentric drivers share the same air-space?....if so, one of them HAS to be out-of-phase from the other....if they don't share the same air-space, I'd be hard-pressed to come up with an answer.....

I’m not sure. The cabinet is not very large, yet the speaker is rated to go down to 65hz. If there is a physical wall between the two drivers, the inside of the enclosure would be pretty small.
