audible diff between 1 ohm or 2 ohm?

Is there a audible difference between wiring a subwoofer 1 ohm or 2 ohm? I looked it up and they said that there is no diff. that the human ear can pick up but I wanted to ask the pros, so what say you guyz?

im not a pro... but from what i know it depends on the wattage difference. but ive also heard that there is not really a big difference, not enough to be able to tell atleast.

In theory, 3dB louder on the SAME amp, but in practice, less than 3dB difference, and that's if the amp even truly doubles power from 2 to 1 ohm. Usually they can't.

Acoustically, ZERO difference.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Don't you mean audibly?

audibly and acoustically I think is different.

Like clipping...it isn't audible until around 10% I think.

Acoustically just pertains to the actual sound.

Audibly is where "you" can hear it.

Correct?

That was what I was saying.. While it sounds the same (audible), were it miced/metered there would be differences between the two (acoustic). Right?

What kind of a woofer do you have that is capable of these 2 impedances? A dual 2 Ohm that will be paralleled to achieve 1 Ohm. And for the 2 Ohm load you would have to use only one coil of the woofer.

The 2 choices for a 2 ohm dual voice coil woofer would be 1 ohm or 4 ohms.
If you are asking about the difference of wiring an amp 1 ohm vs. 2 ohms, as stated above the amp will theoretically double it's power which would give you a 3 Db increase. This is what it takes for the human ear to notice a difference. But in order to go from 2 ohms to 1 ohm you would need different speakers. Then the efficiency of all speakers in the equation will come into play. So we really can't answer your question. If the question would be about 1 ohm vs. 4 ohms then it would be easier to answer. If the amp is 1 ohm stable then yes there would be an audible difference. A very noticeable one. The 1 ohm vs. 2 ohm, too many things would have to change to accomplish the load change. different speakers or using one coil of a dual voice coil speaker which will change the efficiency of said speaker.

Huh... never thought about it like that... From the science side - as in the study of sound and theories applied, "acoustically" is correct, I think. From the environment side - as in what you hear, "audibly" is correct.

I'll have to look further into this.

Maybe what I meant to say was this:
Acoustically, 3dB difference. Audibly, less than that.

o yeah, what I would have meant was 1 ohms vs 2 ohms
