You got all these 2 and 4 channel amps with 2ohm ratings......why no 2ohm speakers?

I realize many cars come with 2ohm speakers from the factory. So why isn't the aftermarket doing the same?

Sound quality, more ohms doesn't exactly mean better sq but don't really see any high end 2 ohm speakers jus sayin. But yeah u have two ohm ratings if you want to run more than 1 speaker per channel and sacrifice sq. For more watts

There are several that do, Harman (JBL,Infinity), Polk MM ,powerbass, the dcr on a lot are around 2.7ohm if you hook a dmm to them

there are alot that do it especially kicker/stillwater old schools, but in all honesty the lower the ohm rating usually the sh1ttier the sound...

It's a marketing angle for some companies to use a nominal impedance of less than 4 ohms. To the average nondiscriminating ear it doesn't really matter. If everyone was doing it there would be no reason to advertise it.

I never understood this. If you look at subwoofers, lower ohm rating meant lower QTS and QES, which means better cone control and sound quality.

The QES of a driver is about is about the least important thing I can think of when it comes to SQ, unless we are talking about matching the QTS of the driver and using the system to compensate, that is important. However to say a high Q driver inherently sounds worse than a low Q driver is incorrect.

Also why changing just the impedance of a driver will have an effect on the speakers QES, BL still dominates the issue. If you want a speaker with a low Q, use a strong motor, making the driver .25ohm isn't nearly as effective and very impractical for many reasons. Shoot the lowest Q drivers you'll likely find are mostly pro audio speakers which are almost all 8 or 16ohm.

anyone know how a stock hu can Handel these 2ohm speakers?

most all of the specs, as far as thd, thd+n, damping factor, head room, channel separation and so on are usually taken at 4 ohms.
Now if you have an amp(just an example) that is 500 w rms @ 4 ohms with .08%thd+n and has 1.5db of head room and a damping factor or ...200..well now load that amp at 2
ohms. For the most part, the thd will have a "big" jump, the head room will nearly be cut in half...if not more and you can loose up to half of your damping factor as well.
Plus the efficiency of the amp will go down a good bit as well. (not all amps will have the same effects as bad as others will...class a/b amps seem to do well vs others but still lose out some into lower loads..)

That is a good question. I have not seen or herd any real complaints so far.
I would think with "rise" they should do fine...

THD goes up but overall remains very low.
Damping factor is not even worth looking at, it is a useless incomplete spec when looking at amplifiers
Head room.... power doubles so you get an extra 3DB of head room compared to 4ohm (assuming power doubles).

I have a set of polk mm 6/9's that are two ohm, and they actually sound pretty decent on the factory installed boston acoustic amps.

In answer to the title question.... because the market hasn't demanded it.

If there were sufficient demand for 2Ω mid/high speakers, they would be in ready supply.

My jbls read 3.7 ohms so I'm guessing that's how. They were no where near the 2 ohm rating. Makes me kinda hate jbl. Head units shouldn't be able to handle a real 2 ohm load.

Did you short your leads to see what the meter read before you measured the speakers?

JBL and Infinity use "True 4 Ohm" marketing terminology with a 2 ohm speaker because they say your factory speaker wires will add roughly 2 ohms. It all changes with music playing anyway.

Correct me if Im wrong.
I always thought less ohms = more bass (punch) over the sound quality(clarity)
and more ohms = less bass (punch) and more sound quality (clarity)

I didn't short the leads, and I refuse to believe their marketing terminology. I bought the amp for the 2 ohm power and the jbls are only drawing a 4 ohm load from the amp. I could have got some regular 4 ohm speakers. I haven't seen 2 ohms added while playing music.

yeah my stillwaters sounded good too, but finding some 2 ohm 6x9's to match is hassle....
