That still doesnt prove anything other then more power... in which case power does not always mean louder... and you should know that.

For that not to be the case the difference in reference efficency would have to be more than 3 Db and if we are still talking about 6.5" door speakers that would be pretty rare (but it is possible).

If that were the case anyway.. why would companies all design their speakers with 4ohm independences if the power is much more achievable through 2ohm speakers. According to Image Dynamics site, they list that the 2ohm version midbass need 150w, and the 4ohms need 75w...so explain that..

The OEM's design their speaker to work for the maximum # of consumers, unless they are going after a niche market (like ID and Soundstream). The VAST majority of consumers run their stock radio or an aftermarket radio, both of which can not handle a 2 ohm load on their little IC chip amps that they use. If a manufactuer creates a 2 ohm component set, they have eliminated ALL of those consumers right off the bat. Thats why 99% of the car audio speakers (mids and highs) are 4 ohm.

If thats the case, it takes more power to run a 2ohm speaker then a 4ohm.. making it the worse choice in most circumstances.

True, but most amps make more power at 2 ohms than 4 ohms, so you are getting more bang for your buck. Its the same reason that you match the impedance of your subs to the amp. If I run my Memphis Belle's sub section into a 4 ohm load I get around 250 watts of power, if I run it into a 2 ohm load it puts out appx 500 watts, and if i give it a 1 ohm load it puts out 1000 watts.

Anyways, I'm not trying to battle you about it. I kinda came off sounding like that, and obviously you know your stuff so I appologize for that.

No sweat, I'm just trying to help dispel a few of the audio BS myths that everyone has heard and help a fellow TN'r out. Its all good.
