    why no 2ohm speakers?

    why is it that so few manufacturers make svc2ohm components? so many a/b amps are 2 ohm stable, why are almost all comp speakers svc 4?

    yes not to mention 2 ohm speakers would save people a lot of money in the long run.

    Re: why no 2ohm speakers?

    Apparently you are unaware of that when you take sensitivity/efficiency into account... they'res really little to no difference in using 4ohm and less power versus 2ohm and more power...

    cause its easier to get the proper ammount of power @ 2 ohms than 4. for instance you got speakers that need 200 watts. the same brand amp that puts out 200 watts @ 4 ohms will cost more than the one that puts out the 200 watts @ 2 ohms. same concept with running subwoofers at 1 ohm and such, because any amp that does good power at 4 ohms costs an arm and a leg. just my .02

    make sense? dont know if i explained that very well

    i didnt ignore it, i just dont understand it.

    edit: ohhh now i get it. i thought you were talkin about something else. i THINK you misunderstood what he was trying to get at...or maybe i did. to me i believe your saying there is not difference between a 2 ohm and 4 ohm speaker if they both have the same wattage...correct?

    what im saying is that you can get amps that put out good power at two ohms for cheaper than you can get amps that put out the same power at 4 ohms...which is why im arguing that i think 2 ohm speakers would save people money

    Re: why no 2ohm speakers?

    No, you must misunderstand.

    A 4 ohm driver given 100 watts will have about the same output as a 2 ohm driver given 200 watts. This is assuming everything else is equal. This relates to sensitivity, not power handling.

    Re: why no 2ohm speakers?

    lower impedance hurts thermal power handling as well...

    they would have to make the unit beefier to handle the increased in current. about 40% more, roughly...

    dont have time to read the thread right now. but will later.

    im not understanding though. so what your saying is that by nature a 2 ohm driver is less sensitive than a 4 ohm driver and therefore the outputs will be relativly similar?

    Re: why no 2ohm speakers?

    ng is right. the lower the impedance, the less efficient the speaker is. its due to the length of the wire in the voice coil. more length of wire to the voice coil will result to the speaker being more efficient. thats why when i was running a pair of Peerless SLS 8" (8 ohm speakers), getting about 150 x 2 @ 4 ohms so getting 75 watts, they absolutely pounded. Output was unreal. so for me, i will not hesitate to run an 8 ohm speaker in my car due to the speaker being much more efficient. you guys should all read that article though.
