why no 2ohm speakers?

....but I am pretty sure you mentioned Single Voice Coil?....**** the singles...but nothing is different with a 4-ohm DVC and a 2-ohm DVC besides wiring capabilities and amp compatibilities. At least that is my experience....but I am sure I will be bad-mouthed in 1....2....3....4.....

I think the basic point was that you have to look at the sensitivity of the driver when selecting one. You can't just look to see if t is 4 ohms, 8 ohms, or 2 ohms.

Comparing the sensitivity is always a GREAT rule of thumb... //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Not to bust balls, but I believe it's traditional to count DOWN to an event.

edit- Actually of ******* course this was to bust balls.

But you have to make sure that you compare apples to apples when you do compare sensitivities. Most sensitivity specs are 2.83V*1m which is 1 watt for an 8 ohm driver but 2 and 4 watts for 4 and 2 ohm drivers respectively. With that a 4 ohm driver that is 2dB more sensitive than an 8 ohm driver will acutually be less sensitive watt for watt than the 8 ohm driver.

Very true...

I guess that I always try to match my sensitivities.

Except when running active. Then it really doesn't matter that much because you have a gain knob... //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

So whats the difference in a set of 4 ohm or 2 ohm components if they have the same sensitivity.

Could be a number of factors.

When looking at sensitivities of component sets you have to be VERY wary of how the sensitivity is measured.

First is, and I've seen this a lot is the manufacturer uses the most sensitive driver, the tweeter to measure the sensitivity of the set. So, you have a set that's rated 93db @ 1w/1m. Well, they're probably using the tweeter. Not at all accurate.

Another is, when you take two drivers of the same diameter, and same impedance, but one is 3 db more sensitive, it's a good bet that it will not have the low end thump of the driver that's 3 db less. Hoffman's Law VERY, VERY simply stated. Give me a break guys. Go to partsexpress and take a look at the sensitivities of an 8", 8 ohm home audio driver, and an 8", 8 ohm pro audio driver. You'll notice the pro-audio driver is much more sensitive in most cases. That pro-audio driver will not have the same low end attack though.

There are a ton of other other variables as well. Unfortunately, we exist in a market where truth is subjective, and manufacturers can play with numbers.

i think this whole thing with the indepence if baiscaly the same if you have the same model wether itll be 2ohm 4 or 8 its have the same effect no matter if you give them all the same power but you got to also look at alot of home audio and PA systems most of them are 8 ohm range and its all on how the speaker is made for. look at how loud a regualr pa speaker can get compared to another driver that takes 4-5 times more power. its all bout design and what works best with the application wether it be home car or else where and the type of power available i think

i know i know didnt make much sence but im lost right now
